Abstract
Switching of multiple physical properties by external stimuli in dynamic materials enables applications in, e.g., smart sensors, biomedical tools, as well as data-storage devices. Among stimuli-responsive materials, inorganic-organic molecular hybrids exhibiting thermal order-disorder phase transitions were tested as promising molecular switches of electrical characteristics, including dielectric constant. We aimed at broadening the multifunctional potential of such hybrid materials towards the switching of not only electrical but also other physical properties, e.g., light emission. We report two ionic salts based on luminescent tetracyanidonitridorhenate(V) anions bearing two different diamine ligands, 1,2-diaminoethane (1) and 1,3-diaminopropane (2), both crystallizing with polar N-methyl-dabconium cations. They exhibit an order-disorder phase transition related to the heating-induced turning-on of the rotation of polar cations. This leads to a unique synchronous switching of the dielectric constant as well as metal-complex-centered photoluminescence, as demonstrated by changes in, e.g., emission lifetime. The roles of organic cations, non-trivial Re(V) complexes, and their interaction in achieving the coupled thermal switching of electrical and optical properties are discussed utilizing experimental and theoretical approaches.

Abstract
![]()
Second coordination sphere interactions
of cyanido complexes with hydrogen-bonding solvents and Lewis acids
are known to influence their electronic structures, whereby the non-labile
attachment of B(C6F5)3 resulted in
several particularly interesting new compounds lately. Here, we investigate
the effects of borylation on the properties of two FeII cyanido complexes in a systematic manner by comparing five different
compounds and using a range of experimental techniques. Electrochemical
measurements indicate that borylation entails a stabilization of the
FeII-based t2g-like orbitals by up to 1.65 eV,
and this finding was confirmed by Mössbauer spectroscopy. This
change in the electronic structure has a profound impact on the UV–vis
absorption properties of the borylated complexes compared to the non-borylated
ones, shifting their metal-to-ligand charge transfer (MLCT) absorption
bands over a wide range. Ultrafast UV–vis transient absorption
spectroscopy provides insight into how borylation affects the excited-state
dynamics. The lowest metal-centered (MC) excited states become shorter-lived
in the borylated complexes compared to their cyanido analogues by
a factor of ∼10, possibly due to changes in outer-sphere reorganization
energies associated with their decay to the electronic ground state
as a result of B(C6F5)3 attachment
at the cyanido N lone pair. Borylation
in the second coordination sphere of two well-known
FeII cyanido complexes leads to isocyanoborato complexes.
The effects of borylation on their electronic structure and photophysical
properties are thoroughly investigated with a range of experimental
techniques.

Abstract
We report colour/luminescence colour changes of M[Ru(bpy)(CN)4] crystal (M2+ = Ca2+, Sr2+, and Ba2+; bpy = 2,2'-bipyridine). The X-ray crystallographic study revealed that the crystals are constructed from linear-chains of {[Ru(bpy)(CN)4][Ca(H2O)5]}n, {[Ru(bpy)(CN)4][Sr(H2O)6]}n, and {[Ru(bpy)(CN)4]2[Ba(H2O)5]2(μ-H2O)2}n, respectively. Ru(II) complex linear chains and the hydrophilic channels composed of M2+ ion and water along them enable reversible water sorption/desorption without collapse of crystals responsible for the colour change. The emission spectra of Ca2+ and Sr2+ salts are remarkably shifted to the red side when the temperature was increased from 296 to 500 K, while Ba2+ salt shows a slight shift in the emission spectrum during the heating. The change in the interaction of M2+ ion to the equatorial CN ligand depending on the number of hydrated water molecules effectively contributes to the luminescence colour change for Ca2+ and Sr2+ salts. FT-IR spectra after heating at 473 K show the high-frequency shifts in the CN stretching mode for Sr2+ salt, while no remarkable peak shifts are observed for Ca2+ and Ba2+ salts. Thermogravimetry results indicate that heating over 470 K leads to the desorption of 5H2O from all salts, resulting in {[Ru(bpy)(CN)4][Ca]}n, {[Ru(bpy)(CN)4][Sr(H2O)]}n, and {[Ru(bpy)(CN)4]2[Ba]2(μ-H2O)2}n for linear chains. The change in the hydration structure for M2+ ions regulates the shift of CN stretching modes.

Abstract
A new class of luminescent bis(bipyridyl) Ru(ii) pyridyl acyclic carbene complexes with environmentally-sensitive dimerization equilibrium have been developed. Owing to the involvement of the orbitals of the diaminocarbene ligand in the emissive excited state, the phosphorescence properties of these complexes are strongly affected by H-bonding interactions with various H-bonding donor/acceptor molecules. With the remarkable differences in the emission properties of the monomer, dimer, and H-bonded amine adducts together with the change of the dimerization equilibrium, these complexes can be used as luminescent gas sensors for humidity, ammonia, and amine vapors. With the responses to amines and humidity and the corresponding change in the luminescence properties, a proof-of-principle for binary optical data storage with a reversible concealment process has been described.

Abstract
Complexes with the formula [M(diimine)(CN-BR3)4]2-, where diimine = bipyridine (bpy), phenanthroline (phen), 3,5-trifluoromethylbipyridine (flpy), R = Ph, C6F5, and M = FeII, RuII, were synthesized and characterized by X-ray crystal structure analysis, UV-visible spectroscopy, IR spectroscopy, and voltammetry. Three highly soluble complexes, [FeII(bpy)(CN-B(C6F5)3)4]2-, [RuII(bpy)(CN-B(C6F5)3)4]2-, and [RuII(flpy)(CN-B(C6F5)3)4]2-, exhibit electrochemically reversible redox reactions, with large potential differences between the bpy0/- or flpy0/- and MIII/II couples of 3.27, 3.52, and 3.19 V, respectively. CASSCF+NEVPT2 calculations accurately reproduce the effects of borane coordination on the electronic structures and spectra of cyanometallates.

Abstract
We describe an Ir(III)-based small-molecule, multimodal probe for use in both light and electron microscopy. The direct correlation of data between light- and electron-microscopy-based imaging to investigate cellular processes at the ultrastructure level is a current challenge, requiring both dyes that must be brightly emissive for luminescence imaging and scatter electrons to give contrast for electron microscopy, at a single working concentration suitable for both methods. Here we describe the use of Ir(III) complexes as probes that provide excellent image contrast and quality for both luminescence and electron microscopy imaging, at the same working concentration. Significant contrast enhancement of cellular mitochondria was observed in transmission electron microscopy imaging, with and without the use of typical contrast agents. The specificity for cellular mitochondria was also confirmed with MitoTracker using confocal and 3D-structured illumination microscopy. These phosphorescent dyes are part of a very exclusive group of transition-metal complexes that enable imaging beyond the diffraction limit. Triplet excited-state phosphorescence was also utilized to probe the O2 concentration at the mitochondria in vitro, using lifetime mapping techniques.

Abstract
To improve the emission and excited-state properties of luminescent cyanometalates, new classes of highly solvatochromic luminescent cyanoruthenium(II) and cyanoruthenate(II) complexes of the general formulae [Ru(PR3)2(CN)2(NN)] and K[Ru(PR3)(CN)3(NN)], respectively, were developed. These complexes could be readily synthesized through the ligand-substitution reaction of K2[Ru(CN)4(PR3)2] with a diimine ligand. The geometrical isomerism of these complexes was characterized by using various spectroscopic techniques. Their photophysical properties, solvatochromism, and electrochemistry have also been investigated. Our detailed study showed that many of these complexes exhibited extremely environmentally sensitive emissions and significantly improved emission quantum efficiencies and lifetimes compared with the well-studied tetracyanoruthenate systems.

Abstract
Reaction of α-pyridoin and N-phenyl-o-phenylenediamine affords 2-(2-(phenylamino)phenylimino)-1,2-di(pyridin-2-yl)ethanol (L) which undergoes cyclization to a chiral diimine, 2-methoxy-1-phenyl-2,3-di(pyridin-2-yl)-1,2-dihydroquinoxaline, L(OMe) (conjugated 14πe system) in the presence of zinc(II), cadmium(II) and mercury(II) ions affording [Zn(L(OMe))Cl2] (1), [Cd2(L(OMe))2Cl4] (2) and [Hg2(L(OMe))2Cl4] (3) complexes. Ligand L and complexes 1-3 are substantiated by elemental analyses, mass, IR, (1)H NMR and UV-vis spectra including the single-crystal X-ray structures of 1 and 3. The possibility of the atropisomerism of L is restricted in cyclic L(OMe). L and complexes 1-3 are fluorescent in fluid solutions at 298 K (CH2Cl2: 1, λ(ex) = 470 nm, λ(em) = 627 nm, Φ = 0.014, τ(avg) = 2.5 ns; 2, λ(ex) = 430 nm, λ(em) = 599 nm, Φ = 0.08, τ(avg) = 7.6 ns; 3, λ(ex) = 415 nm, λ(em) = 600 nm, Φ = 0.021, τ(avg) = 2.8 ns). Time-resolved emission spectra (TRES) established that the two-component lifetimes of 1-3 are due to the existence of two conformers. Density functional theory (DFT) and time dependent (TD) DFT calculations authenticated that 1-3 complexes are fluorescent due to intra-ligand charge transfer (ILCT) to the π(diimines)* orbital.

Abstract
Three complexes [ Ru ( CN )4( HAT )]2-( HAT = hexaazatriphenylene ;[ Ru 1]2-), [{ Ru ( CN )4}2 (μ2- HAT )]4-([ Ru 2]4-) and [{ Ru ( CN )4}3(μ3- HAT )]6-([ Ru 3]6-) for supramolecular assemblies are investigated by quantum-chemical calculations. Due to symmetry of complexes, the energy level differences are 2.014 eV and 2.019 eV for [ Ru 2]4- and [ Ru 3]6- complex, which are about 0.4 eV larger than that for [ Ru 1]2- complex. The absorption maximum for [ Ru 1]2- complex in water is at 375.8 nm. Coordination of the second and third Ru(II) center to produce [ Ru 2]4- and [ Ru 3]6- result in a red-shift of this strongest absorption to 453.4 nm and 468.1 nm, respectively. Absorption maximum of three complexes belong to MLCT transitions, which are revealed by frontier molecular orbital theory and charge difference density method.

Abstract
Ruthenium(II) hydrazone Schiff base complexes of the type [RuCl(CO)(B)(L)] (were B=PPh(3), AsPh(3) or Py; L=hydrazone Schiff base ligands) were synthesized from the reactions of hydrazone Schiff base ligand (obtained from isonicotinoylhydrazide and different hydroxy aldehydes) with [RuHCl(CO)(EPh(3))(2)(B)] (where E=P or As; B=PPh(3), AsPh(3) or Py) in 1:1 molar ratio. All the new complexes have been characterized by analytical and spectral (FT-IR, electronic, (1)H, (13)C and (31)P NMR) data. They have been tentatively assigned an octahedral structure. The synthesized complexes have exhibited catalytic activity for oxidation of benzyl alcohol to benzaldehyde and cyclohexanol to cyclohexanone in the presence of N-methyl morpholine N-oxide (NMO) as co-oxidant. They were also found to catalyze the transfer hydrogenation of aliphatic and aromatic ketones to alcohols in KOH/Isopropanol.

Abstract
The initial interest in dendrimer chemistry was the synthesis of such aesthetically pleasant macromolecules. Nowadays, the field is moving to applications in various multidisciplinary areas, such as medicine, biology, chemistry, physics, and engineering, i.e. at the interface of many disciplines. This short review describes some promising applications of photoactive and electroactive dendrimers as artificial enzymes, molecular batteries, sensors with signal amplification, photoswitchable hosts, systems for energy up-conversion, and light-harvesting antennas. The reported examples clearly show that these applications take advantage of the unique aspects of dendrimer structure: (i) three-dimensional array; (ii) generation-dependent size; (iii) presence of selected functional units in predetermined sites; and (iv) endo- and exo-receptor capabilities.
