Abstract
Organic phototheranostic nanomedicines with an optimized near-infrared (NIR) biological transparent window (700-900 nm) are highly desirable for the diagnosis and treatment of deep-seated tumors in clinic. As excellent organic photosensitizers for photodynamic therapy (PDT) with outstanding photo- and thermo-stability, phthalocyanines (Pcs) have been used as the building blocks of single-component nanomedicines. However, to the best of our knowledge, all the Pc-based single-component self-assemblies reported to date are of an H-aggregate nature. This results in the simultaneous self-quenching of fluorescence emission and photodynamic activity as well as greatly reduced tissue penetration due to blue-shifted absorption. In the present work, intramolecular hydrogen bonding was formed between the two long and flexible axial NH2-terminated diethylene glycol ligands of the amphiphilic SiPc molecule (SiPc-NH2) in solution, leading to the employment of a cis-conformation of this molecule according to the 1H-NMR spectroscopy result, which as a building block then further self-assembled into monodisperse nanospheres (SiPcNano) with a J-aggregation nature on the basis of electronic absorption spectroscopic results. As a result, SiPcNano exhibited significantly enhanced red-shifted absorption in the NIR range of 750-850 nm and fluorescence emission. This in combination with the increased photodynamic effect for SiPcNano triggered by the protonation of amine groups due to the acidic nature of tumors endowed effective synergistic NIR photodynamic and photothermal effects in different cancer cells and thus effective inhibition of tumor growth in A549 tumor-bearing mice on the basis of a series of in vitro and in vivo evaluations. The present result provides a new approach for constructing novel single-component NIR organic nanomedicines for multifunctional cancer therapy.

Abstract
Axially di-(alpha,alpha-diphenyl-4-pyridylmethoxy) silicon(IV) phthalocyanine (3) and its quaternized derivative (3Q) were synthesized and tested as photosensitizers against tumor and bacterial cells. These new phthalocyanines were characterized by elemental analysis, and different spectroscopic methods such as FT-IR, UV-Vis, MALDI-TOF and 1H NMR. The photophysical properties such as absorption and fluorescence, and the photochemical properties such as singlet oxygen generation of both phthalocyanines were investigated in solutions. The obtained values were compared to the values obtained with unsubstituted silicon(IV) phthalocyanine dichloride (SiPcCl2). The addition of two di-(alpha,alpha-diphenyl-4-pyridylmethanol) groups as axial ligands showed an improvement of the photophysical and photochemical properties and an increasement of the singlet oxygen quantum yield (ΦΔ) from 0.15 to 0.33 was determined. The photodynamic efficacy of synthesized photosensitizers (3 and 3Q) were evaluated with promising photocytotoxicity (17% cell survival for 3 and 28% for 3Q) against the cervical cancer cell line (HeLa). The photodynamic inactivation of pathogenic bacterial strains Streptococcus mutans, Staphylococcus aureus, and Pseudomonas aeruginosa suggested a high susceptibility with quaternized derivative (3Q). The both Gram-positive bacterial strains were fully photoinactivated with 11μM 3Q and mild light dose 50J.cm-2. In case of P. aeruginosa the effect was negligible for concentrations up to 22μM 3Q and light dose 100J.cm-2. The results suggested that the novel axially substituted silicon(IV) phthalocyanines have promising characteristic as photosensitizer towards tumor cells. The quaternized derivative 3Q has high potential for photoinactivation of pathogenic bacterial species.

Abstract
An unsymmetrical phthalocyanine based one- and two-photon fluorescence imaging probe that substituted with 4-tert-butylphenoxy and RDGyK moieties was developed and characterized by UV-vis and high-resolution MALDI-TOF/MS. The conjugate is non-aggregated in [Formula: see text],[Formula: see text]-dimethylformamide, with relatively weak fluorescence emission ([Formula: see text] 0.023) and high singlet oxygen quantum yield ([Formula: see text] 0.55). Conjugation of the cyclic peptide sequence c(RGDyK) can enhance the cellular uptake towards the DU145 and PC3 cells. While the fluorescence is greatly enhanced in mitochondria, the conjugate is non-cytotoxicity either in dark or upon exposure to red-light with dose up to 12 J.cm[Formula: see text]. The results suggest that this conjugate is a promising multifunctional imaging probe for mitochondria and cancer.
