Abstract
In this study, a new phthalonitrile derivative namely 4-[(2,4-difluorophenyl)ethynyl]phthalonitrile (1) and its metal phthalocyanines (2 and 3) were synthesized. The resultant compounds were conjugated to silver nanoparticles and characterized using transmission electron microscopy (TEM) images. The biological properties of compounds (1-3), their nanoconjugates (4-6), and silver nanoparticles (7) were examined for the first time in this study. The antioxidant activities of biological candidates (1-7) were studied by applying the 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging assay. The highest antioxidant activity was obtained 97.47 % for 200 mg/L manganese phthalocyanine-silver nanoconjugates (6). The antimicrobial and antimicrobial photodynamic therapy (APDT) activities of biological candidates (1-7) were examined using a micro-dilution assay. The highest MIC value was obtained 8 mg/L for nanoconjugate 6 against E. hirae. The studied compounds and their silver nanoconjugates exhibited high APDT activities against all the studied microorganisms. The most effective APDT activities were obtained 4 mg/L for nanoconjugates (5 and 6) against L. pneumophila and E. hirae, respectively. All the studied biological candidates displayed high cell viability inhibition activities against E. coli cell growth. The biofilm inhibition activities of the tested biological candidates were also investigated against S. aureus and P. Aeruginosa. Biological candidates (1-6) can be considered efficient metal nanoparticle-based materials for multi-disciplinary biological applications.

Abstract
The equilibrium solution adsorption of perfluorinated metal phthalocyanines FXPcZn (x = 16, 64) on titania was investigated. This method was explored as an alternative to the frequently used vapor deposition technique for the preparation of solid-supported phthalocyanines for applications such as sensitizers, catalysts, and sensors. According to X-ray photoelectron spectroscopy (XPS), UV-vis, and water contact angles, the adsorption of phthalocyanines from acetone solution occurred readily at room temperature resulting in the formation of hydrophobic surfaces of the solid-supported phthalocyanines. The adsorption isotherms (298 K) were of the Langmuir-type with saturation plateau. The effective thickness of the adsorbed layers at the plateau regions was estimated at 0.17 nm (F16PcZn) and 0.47 nm (F64PcZn), which, assuming the face-down orientation of phthalocyanines, corresponded to ∼52 and ∼77% of the complete monolayers, respectively. In the case of F64PcZn, the state of the adsorbed molecules was similar to that of bulk F64PcZn, suggesting only weak adsorption interactions of dispersive type. In contrast, F16PcZn showed strong interactions with the surface of titania including the dissociation of C-F bonds, i.e., chemisorption. The difference in the adsorption interactions of F16PcZn vs F64PcZn was attributed to the presence of eight i-C3F7 groups decorating the perimeter of the F64PcZn molecule. These bulky substituents in the peripheral positions sterically protected the nonperipheral fluorine atoms, thereby preventing their substitution and any other specific interactions between the macrocycle and the surface OH groups.

Abstract
Dye-sensitized TiO2 has found many applications for dye-sensitized solar cells (DSSC), solar-to-chemical energy conversion, water/air purification systems, and (electro)chemical sensors. We report an electrochemical system for testing dye-sensitized materials that can be utilized in photoelectrochemical (PEC) sensors and energy conversion. Unlike related systems, the reported system does not require a direct electron transfer from semiconductors to electrodes. Rather, it relies on electron shuttling by redox mediators. A range of model photocatalytic materials were prepared using three different TiO2 materials (P25, P90, and PC500) and three sterically hindered phthalocyanines (Pcs) with electron-rich tert-butyl substituents (t-Bu4PcZn, t-Bu4PcAlCl, and t-Bu4PcH2). The materials were compared with previously developed TiO2 modified by electron-deficient, also sterically hindered fluorinated phthalocyanine F64PcZn, a singlet oxygen (1O2) producer, as well as its metal-free derivative, F64PcH2. The PEC activity depended on the redox mediator, as well as the type of TiO2 and Pc. By comparing the responses of one-electron shuttles, such as K4Fe(CN)4, and 1O2-reactive electron shuttles, such as phenol, it is possible to reveal the action mechanism of the supported photosensitizers, while the overall activity can be assessed using hydroquinone. t-Bu4PcAlCl showed significantly lower blank responses and higher specific responses toward chlorophenols compared to t-Bu4PcZn due to the electron-withdrawing effect of the Al3+ metal center. The combination of reactivity insights and the need for only microgram amounts of sensing materials renders the reported system advantageous for practical applications.

Abstract
Electron-withdrawing perfluoroalkyl peripheral groups grafted on phthalocyanine (Pc) macrocycles improve their single-site isolation, solubility, and resistance to self-oxidation, all beneficial features for catalytic applications. A high degree of fluorination also enhances the reducibility of Pcs and could alter their singlet oxygen (1O2) photoproduction. The ethanol/toluene 20:80 vol % solvent mixture was found to dissolve perfluorinated FnPcZn complexes, n = 16, 52, and 64, and minimize the aggregation of the sterically unencumbered F16PcZn. The 1O2 production ability of FnPcZn complexes was examined using 9,10-dimethylanthracene (DMA) and 2,2,6,6-tetramethylpiperidine (TEMP) in combination with UV-vis and electron paramagnetic resonance (EPR) spectroscopy, respectively. While the photoreduction of F52PcZn and F64PcZn in the presence of redox-active TEMP lowered 1O2 production, DMA was a suitable 1O2 trap for ranking the complexes. The solution reactivity was complemented by solid-state studies via the construction of photoelectrochemical sensors based on TiO2-supported FnPcZn, FnPcZn|TiO2. Phenol photo-oxidation by 1O2, followed by its electrochemical reduction, defines a redox cycle, the 1O2 production having been found to depend on the value of n and structural features of the supported complexes. Consistent with solution studies, F52PcZn was found to be the most efficient 1O2 generator. The insights on reactivity testing and structural-activity relationships obtained may be useful for designing efficient and robust sensors and for other 1O2-related applications of FnPcZn.

Abstract
This study presents the preparation of a novel tetra-substituted phthalonitrile (1), namely, 3,6-bis(hexyloxy)-4,5-bis(4-(trifluoromethoxy)phenoxy)phthalonitrile (1) and its metal-free (2)/metal {M = Zn (3), Cu (4), Co (5), Lu(CH3COO) (6), Lu (7)} phthalocyanines. A series of various spectroscopic methods (UV-vis, FT-IR, mass, and 1H NMR spectroscopy) were performed for the characterization of the newly synthesized compounds. The potential of compounds 2, 3, and 6 as photosensitizing materials for photodynamic and sonophotodynamic therapies was evaluated by photophysical, photochemical, and sonochemical methods. The highest singlet quantum yields were obtained for the zinc phthalocyanine derivative 3 by performing photochemical and sonochemical methods. In addition, several biological activities of the new compounds 1-7 were investigated. The newly synthesized phthalocyanines exhibited excellent DPPH scavenging activity and also DNA nuclease activity. The antimicrobial activity of the new compounds was evaluated by the disc diffusion assay. Effective microbial cell viability inhibition was observed with phthalocyanine macromolecules. The photodynamic antimicrobial therapy of the phthalocyanines showed 100% bacterial inhibition when compared to the control. They also exhibited significant biofilm inhibition activity against S. aureus and P. aeruginosa. These results indicate that new phthalocyanines are promising photodynamic antimicrobial therapies for the treatment of infectious diseases.

Abstract
As thiazoles and fluorinated groups are well known as active species of hybrid pharmaceutical agents, this study aimed to evaluate the synergic effect of these groups on the biological features of phthalocyanines for the first time in the hope of discovering efficient pharmaceutical agents. Therefore, a new phthalonitrile derivative namely 4-(2-(4-methylthiazol-5-yl)ethoxy)-5-(4-(trifluoromethoxy)phenoxy)phthalonitrile (1) and its metal-free (2)/metal phthalocyanines (3-5) were prepared and characterized using various spectroscopic techniques. Solubility of new phthalocyanines (2-5) was examined in a series of polar and nonpolar solvents. Additionally, sono/photochemical methods were applied to examine the photophysical and sono/photochemical properties of new zinc phthalocyanine to measure its potential as a probable material for sono/photodynamic therapies. The antioxidant activities of compounds (1-5) were evaluated using the DPPH scavenging activity method and the highest radical scavenging activity was obtained 92.13% (200 mg L-1 ) for manganese phthalocyanine. All the phthalocyanines demonstrated high DNA nuclease activity, as well. The antimicrobial activities of compounds (1-5) were investigated using disk diffusion and microdilution methods. The phthalocyanines exhibited effective microbial cell inhibition activity against Escherichia coli (E. coli). Antimicrobial photodynamic therapy activity was investigated against E. coli by LED irradiation. Compounds (2-5) acted as photosynthesizers. Also, they displayed significant biofilm inhibition activity against Staphylococcus aureus (S. aureus) and Pseudomonas aeruginosa (P. aeruginosa).

Abstract
Metal phthalocyanines bearing electron-withdrawing fluorine substituents were synthesized a long time ago, but interest in the study of their films has emerged in recent decades. This is due to the fact that, unlike unsubstituted phthalocyanines, films of some fluorinated phthalocyanines exhibit the properties of n-type semiconductors, which makes them promising candidates for application in ambipolar transistors. Apart from this, it was shown that the introduction of fluorine substituents led to an increase in the sensitivity of phthalocyanine films to reducing gases. This review analyzes the state of research over the last fifteen years in the field of applications of fluoro-substituted metal phthalocyanines as active layers of gas sensors, with a primary focus on chemiresistive ones. The active layers on the basis of phthalocyanines with fluorine and fluorine-containing substituents of optical and quartz crystal microbalance sensors are also considered. Attention is paid to the analysis of the effect of molecular structure (central metal, number and type of fluorine substituent etc.) on sensor properties of fluorinated phthalocyanine films.

Abstract
Perfluoro phthalonitrile substituted separately with perfluoroalkyl (EWG) and NH2, NHMe, and NMe2 (EDG) groups generate a series of aromatic C-H bonds-free nitriles that can now lose electrons, whose HOMO–LUMO gap is narrowed by EDG beyond the level induced by EWG, and whose dipole moments double. Molecular parameters vary linearly with Hammett’s free-energy constants, their electronic underpinning being uncovered by DFT calculations. The phthalonitriles’ assembling in solid-state structures is determined by forces that transition from van der Waals, in the case of EWG, to H-bonding and/or [Formula: see text]-stacking interactions in the case of EDG, as revealed by their single-crystal X-ray structures.

Abstract
A series of new peripherally or nonperipherally substituted phthalocyanines bearing 4-(trifluoromethoxy)thiophenyl groups was synthesized. In addition, a new metal-free phthalocyanine bearing 4-(trifluoromethoxy)phenoxy on the nonperipheral position was prepared. The resulting phthalocyanines were characterized using some spectroscopic techniques such as 1 H nuclear magnetic resonance, Fourier-transform infrared spectroscopy, and UV-Vis spectroscopy, together with elemental analysis. When the tyrosinase enzyme inhibition activities of the synthesized phthalocyanines were examined, molecules 2b and 3b showed an inhibitory activity against the enzyme with IC50 values of 176.2 ± 0.65 and 284.4 ± 1.03, respectively. The inhibition types of the molecules and standard inhibitor kojic acid were found as competitive for 2b, mixed for 1b and kojic acid, and uncompetitive for 3b. Antioxidant activities were also assessed by using 1,1-diphenyl-2-picrylhydrazyl (DPPH) and reducing power assays, and the molecules showed moderate antioxidant activities.

Abstract
The use of a photocatalyst (photosensitizer) which produces singlet oxygen instead of enzymes for oxidizing analytes creates opportunities for designing cost-efficient and sensitive photoelectrochemical sensors. We report that perfluoroisopropyl-substituted zinc phthalocyanine (F64PcZn) interacts specifically with a complex phenolic compound, the antibiotic rifampicin (RIF), but not with hydroquinone or another complex phenolic compound, the antibiotic doxycycline. The specificity is imparted by the selective preconcentration of RIF in the photocatalytic layer, as revealed by electrochemical and optical measurements, complemented by molecular modeling that confirms the important role of a hydrophobic cavity formed by the iso-perfluoropropyl groups of the photocatalyst. The preconcentration effect favorably enhances the RIF photoelectrochemical detection limit as well as sensitivity to nanomolar (ppb) concentrations, LOD = 7 nM (6 ppb) and 2.8 A·M-1·cm-2, respectively. The selectivity to RIF, retained in the photosensitizer layer, is further enhanced by the selective removal of all unretained phenols via simple washing of the electrodes with pure buffer. The utility of the sensor for analyzing municipal wastewater was demonstrated. This first demonstration of enhanced selectivity and sensitivity due to intrinsic interactions of a molecular photocatalyst (photosensitizer) with an analyte, without use of a biorecognition element, may allow the design of related, robust, simple, and viable sensors.

Abstract
This study presents the preparation of a new phthalonitrile derivative namely 3-(4-(trifluoromethoxy)thiophenoxy)phthalonitrile (1) and a series of its metallated phthalocyanines (M = Zn (II) (1a) and In(III) (1b)). In addition, the peripheral analog of the indium phthalocyanine chloride (2b) was newly synthesized. Characterization of the resulting compounds was carried out by utilizing various spectroscopic methods such as FT-IR, 1 H NMR and UV-Vis spectroscopy. The influence of concentration on aggregation properties of compound 1a was investigated at different concentrations of DMSO. The effect of solvent type on aggregation properties of compound 1a was studied, as well. According to the referred procedures, the macrocyclic molecules (2a, 3a-b and 4a-b) were prepared. The effect of some parameters including metal ion, the position of the substituent and the connected atom (oxo or thio) on photochemical and photophysical features of compounds (1a-b, 2a-b, 3a-b, and 4a-b) was studied for evaluation of their potential as a photosensitizer in PDT, comparatively. The highest singlet oxygen quantum yields (ΦΔ = 0.71 for 1a and 0.80 for 2b) were obtained for complexes 1a and 1b in DMSO. The photophysical and photochemical features of the studied macromolecules are therefore suitable for photodynamic therapy applications.

Abstract
Tetra-substituted zinc(II) and copper(II) phthalocyanines bearing peripheral alkoxy-monoterpene groups were prepared by conventional vs. non-conventional synthetic approaches (ultrasound and microwave irradiation). The synthesis of (1[Formula: see text]-(–)-myrtenol (a) and (1[Formula: see text],2[Formula: see text],5[Formula: see text]-([Formula: see text]-menthol (b) derived phthalonitrile precursors was performed through ipso-nitro aromatic substitution reactions, with optimal conditions being obtained using ultrasound irradiation, which allowed us to achieve full conversions in 4.5 h, with isolated yields up to 74%. The subsequent cyclotetramerization of monoterpene-based phthalonitriles was carried out using Zn(II) or Cu(II) salts as metal templates, and also using conventional and non-conventional heating methods. Microwave-assisted synthesis was shown to be the most efficient approach, providing complete conversions in 1 h, yielding the target monoterpene-based metallophthalocyanines in up to 70% isolated yields. Furthermore, photophysical and photochemical studies revealed that Zn(II) phthalocyanines possess fluorescence quantum yields in the range of [Formula: see text] 0.27–0.29, while Cu(II) phthalocyanines exhibited room temperature phosphorescence. In addition, the monoterpene-based Zn(II) phthalocyanines led to high singlet oxygen quantum yields ([Formula: see text] 0.55–0.69).

Abstract
The transport of both electrons and ions in organic mixed ionic and electronic conductors such as phthalocyanines, is essential to allow redox reactions of entire films and, hence, to impart electrochromism. Thin films of a new type, tetrakis-perfluoroisopropyl-perfluoro phthalocyanine, F40PcCu of different thicknesses were obtained via vapor deposition. The extent of the intermolecular coupling within the F40PcCu films established by van der Waals interactions was investigated by in situ optical spectroscopy during film growth. The transfer of electrons and diffusion of counter cations in these films, as well as their electrochromic performance were characterized by electrochemical and spectroelectrochemical measurements with an aqueous solution of KCl as electrolyte. A moderate degree of intermolecular interaction of the F40PcCu molecules in the solid state was observed, compared to non-fluoroalkylated perfluoro phthalocyanine, F16PcCu and octakis-perfluoroisopropyl-perfluorophthalocyanine, F64PcCu, which exhibit stronger and weaker coupling, respectively. The replacement of F by perfluoroisopropyl is, thereby, established as a valuable approach to tune this coupling of chromophores and, hence, the transport coefficients of electrons and ions in the solid films. Reversible changes of the films upon reduction and intercalation of K+ counter ions and re-oxidation and expulsion of the counter ions were confirmed by simultaneously measured optical absorption spectra. Thin films of F40PcCu showed a well-balanced, equally fast transport of electrons and ions. The films provided a fast and reversible switching process over at least 200 cycles indicating the stability of these materials.

Abstract
In this study, the synthesis and characterization of novel 4-chloro-5-((2,3-dihydrobenzo-1,4-benzodioxin-2-yl)methoxy)phthalonitrile (1) and its peripherally octa-substituted Zn(II) (Pc-Zn), In(III) (PcInCI) and Mg(II) (Pc-Mg) phthalocyanine (Pc) derivatives are reported for the first time. FT-IR, elemental analysis, UV-vis, NMR and MS techniques were used for characterization studies of the compounds. Aggregation properties of the compounds were evaluated in DMF, DMSO and THF solvents in different concentrations, and the compounds did not tend to aggregate in these solvents. In addition, photophysicochemical properties such as fluorescence, photodegradation and singlet oxygen quantum yield of the compounds were examined in DMSO, DMF and THF solvents to show the potential use of these novel compounds as photosensitizers for photodynamic therapy (PDT). The effects of zinc, indium and magnesium metals, octa substitutions in peripheral positions and different types of solvents on photophysicochemical properties were investigated. The singlet oxygen quantum yield values of compounds ranged from 0.27 to 0.77 in different solvents. As a result of the photophysicochemical properties, these compounds can be considered as potential candidates for PDT, applications.

Abstract
A unique organic/inorganic nanocomposite of non-aggregated lead sulphide (PbS) quantum dots (QDs) dispersed within a spun film of non-peripherally octakis(hexyl)-substituted metal-free phthalocyanine (C[Formula: see text]H[Formula: see text]Pc) has been prepared at room temperature by a simple and low-cost method. The frequency response of alternating current (AC) conduction in a 130 nm thick C[Formula: see text]H[Formula: see text]Pc /PbS film sandwiched between the indium-tin-oxide (ITO) and aluminum (Al) electrodes is found to obey the universal power-law. The cryogenic study of AC conduction reveals that the correlated barrier hopping (CBH) model closely fits to the experimental data at temperatures below 240 K. The parameters obtained by fitting the CBH model point out that the hopping process cannot take place directly between neighboring PbS QDs but involves the localized states within the matrix.

Abstract
In this work, 5-(trifluoromethyl)-2-thiopyridine substituted SiPc (1) and its quaternized derivative (2) were synthesized, and the effect of the linker sulfur atom on silicon phthalocyanines has been investigated for the first time in the literature. Both of the complexes have been characterized by standard spectroscopy methods. The complexes have good solubility in organic solvents and showed monomeric tendencies in all studied solvents. Only complex 2 had some aggregation in water because of solvent effects, as expected. In order to determine the therapeutic effect for cancer treatment, photophysicochemical properties were investigated in DMSO, DMF, toluene and water (for complex 2). The synthesized complexes were found to have about 3.5 times higher singlet oxygen quantum yields than the yields of unsubstituted SiPcCl2 ([Formula: see text] = 0.15 (in DMSO), 0.12 (in DMF), 0.10 (in toluene)) because of the effects of bulky axial groups.

Abstract
CoPc(COOH)[Formula: see text]-TiO[Formula: see text] nanocomposites to be used as efficient visible light photocatalysts were obtained by modifying TiO2 nanoparticles with cobalt(II) tetracarboxyphthalocyanine (CoPc(COOH)[Formula: see text]). The photocatalyst was then characterized by ultra-violet diffuse reflectance spectroscopy (UV-DRS), Fourier transform infrared spectroscopy (FT-IR) and X-ray diffraction (XRD). The UV-DRS spectra showed that the absorbance spectrum of the modified catalyst was shifted to the visible region. Different textile dye solutions of Reactive Red 180, Acid Red 88 and Direct Orange 46 were efficiently degraded under visible light. Color removal rates were established to be 30%, 53% and 47% after 180 min for RR180, AR88 and DO46 dyes, respectively. The optimum catalyst concentration was determined to be 1 g/L of CoPc(COOH)[Formula: see text]-TiO[Formula: see text]. Development of the CoPc(COOH)[Formula: see text]-TiO[Formula: see text] nanocomposite photocatalyst enabled the utilization of visible light irradiation for efficient photodegradation of organic textile dye solutions.

Abstract
Iron(III) phthalocyaninate decorated with crown ether substituents, [(15C5)4PcFe]Cl, efficiently catalyzed the insertion of carbene derived from ethyl diazoacetate to six amines functionalized with thiazole, thiazoline and thiadiazole heterocycles. The reactions were carried out under practical conditions using EDA:amine stoechiometric ratio with 0.05 mol% catalyst loading. Turnover numbers up to 3360 have been achieved. The aminoacid derivatives bearing heterocyclic moieties were obtained under catalytic conditions for the first time with 36–69% yields in the case of single N–H insertion products and up to 77% in the case of double N–H insertion products.

This study presents a novel phthalonitrile derivative (2) bearing (trifluoromethoxy)phenoxy groups in 4,5 positions. Cyclotetramerization of (2) in [Formula: see text],[Formula: see text]-dimethylaminoethanol (DMAE) gave a series of peripherally octa-substituted metallophthalocyanines (3-Zn, 3-Co and 3-Cu). The newly synthesized phthalocyanines have been characterized by a combination of various spectroscopic techniques. Effects of solvent nature on aggregation behavior of 3-Zn were studied using different solvents such as acetone, CHCl3 and dichloromethane (DCM). In addition, the aggregation behavior of the phthalocyanine complex 3-Zn was examined in DCM at different concentrations ranging from 4 × 10[Formula: see text]–14 × 10[Formula: see text] M. Antimicrobial activities of synthesized compounds were tested by using the thin layer chromotography (TLC)-direct bioautography and disk diffusion methods. In both assays, the molecules showed activity on the tested Gram (+) bacteria. Antioxidant activities of the molecules, on the other hand, were determined by using the 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging method and a reducing power assay. The highest activity was obtained with 3-ZnPc for both methods.
