Complexes of the type (R-bpy)2RuCl2 (R: H, Me, tert-but) were synthesised by microwave-activated reactions of [Ru(cod)Cl 2]n with substituted 2,2?-bipyridines in dimethylformamide in high yields and high purity. Microwave-assisted or thermal reaction of the (R-bpy)2RuCl2 solutions with substituted bibenzimidazoles, 1,10 phenanthroline or bipyrimidine in dmf/water mixtures resulted in the formation of mixed ligand complexes of the type [(R-bpy) 2Ru(L-L)]Cl2. Complexes of the type (R-bpy) 2RuCl2 (R: H, Me, tert-but) were synthesised by microwave-activated reactions of [Ru(cod)Cl2]n with substituted 2,2?-bipyridines in dimethylformamide as the solvent. The complexes were isolated in high yields and high purity from the reaction mixture. Microwave-assisted or thermal reaction of the (R-bpy) 2RuCl2 solutions with substituted bibenzimidazoles, 1,10 phenanthroline or bipyrimidine in dmf/water mixtures resulted in the formation of mixed ligand complexes of the type [(R-bpy)2Ru(L-L)]Cl 2. The complexes were characterised by NMR spectroscopy and MS. Furthermore, their photochemical and electrochemical properties were investigated and the solid state structure of (4-tert-butyl-bpy) 2RuCl2 (3), [(4-tert-butyl-bpy) 2Ru(tetramethylbibenzimidazole)](PF6)2 (4), and [(4-tert-butyl-bpy)2Ru(bipyrimidine] (PF6)2 (5) was determined by X-ray diffraction analysis of single crystals.

The rate constants for photoinduced electron transfer, as well as thermal charge recombination, were measured in a series of <(4,4'-R2-2,2'-bipyridine)2RuII(4'-(CH3)-2,2'-bipyridine-4-(CONHR'))> (R’ = (CH2)x(MV2+) systems, in which a tris(bipyridyl)ruthenium(II) chromophore was covalently linked to a 4,4′-bipyridinium (MV2+) electron acceptor.The nature of R(R = H, CH3, COO-, COOH, CONHCH(CH3)2) and the number (x = 2,3) of intervening methylene units were varied to tune the chromophore’s electronic properties, including the ?* orbital energies of the 4,4′-R2-2,2′-bipyridine ligands and donor-acceptor separation distance, respectively.For a given donor-acceptor distance, x, and similar driving force, the rate constants for forward electron transfer were nearly 60 (x=3) to 400 (x=2) times smaller in complexes in which the two 4,4′-R2-2,2′-bipyridine ligands were R-substituted with electron-withdrawing functional groups (R = CONHCH(CH3)2).Charge recombination from the reduced viologen acceptor to the oxidized metal center occurs in the Marcus inverted region, with the rate constants (kb) decreasing with increasing magnitude of driving force.The kinetics of the bimolecular oxidative quenching of the electronically excited state of these mixed ligand tris(bipyridyl)ruthenium(II) complexes (R’ = CH(CH3)2) by methyl viologen was also characterized in homogeneous aqueous solution, and the escape efficiencies were measured for separation of the redox products from the solvent cage.

An NAD/NADH-functionalized ligand, benzo[b]pyrido[3,2-f][1,7]-phenanthroline (bpp), was newly synthesized. A Ru compound containing the bpp ligand, [Ru(bpp)(bpy)2]2+, underwent 2e- and 2H+ reduction, generating the NADH form of the compound, [Ru(bppHH)(bpy)2]2+, in response to visible light irradiation in CH3CN/TEA/H2O (8/1/1). The UV-vis and fluorescent spectra of both [Ru(bpp)(bpy)2]2+ and [Ru(bppHH)(bpy)2]2+ resembled the spectra of [Ru(bpy)3]2+. Both complexes exhibited strong emission, with quantum yields of 0.086 and 0.031, respectively; values that are much higher than those obtained from the NAD/NADH-functionalized complexes [Ru(pbn)(bpy)2]2+ and [Ru(pbnHH)(bpy)2]2+ (pbn = (2-(2-pyridyl)benzo[b]-1.5-naphthyridine, pbnHH = hydrogenated form of pbn). The reduction potential of the bpp ligand in [Ru(bpp)(bpy)2]2+ (-1.28 V vs SCE) is much more negative than that of the pbn ligand in [Ru(pbn)(bpy)2]2+ (-0.74 V), although the oxidation potentials of bppHH and pbnHH are essentially equal (0.95 V). These results indicate that the electrochemical oxidation of the dihydropyridine moiety in the NADH-type ligand was independent of the pi system, including the Ru polypyridyl framework. [Ru(bppHH)(bpy)2]2+ allowed the photoreduction of oxygen, generating H2O2 in 92% yield based on [Ru(bppHH)(bpy)2]2+. H2O2 production took place via singlet oxygen generated by the energy transfer from excited [Ru(bppHH)(bpy)2]2+ to triplet oxygen.

Four unsymmetric dinuclear ruthenium and osmium complexes, Os(bpy) 3-viologen-Ru(bpy)3 (1; bpy = 2,2?-bipyridyl), Ru(bpy)3-viologen-Ru(bpy)(dcbpy)2 (2; dcbpy = 4,4?-dicarboxyl-2,2-bipyridyl), Os(bpy)3-viologen-Ru(bpy) (dcbpy)2 (3) and rotaxane 1CB[7] (CB[7] = cucurbit[7]uril), were successfully synthesized. The NMR, electrochemistry and photochemistry studies of these complexes were performed in non-aqueous solutions. The results show that the CB[7] host mainly locates at the butyl linker part of the osmium side in an acetonitrile solution. This binding lowers the oxidation potential of osmium whereas the oxidation potential of ruthenium does not change. The oxidation potential of ruthenium in complexes 2 and 3 is higher due to the electron withdrawing property of carboxylic anchor groups. Analysis with UV-vis spectra shows the viologen radical formation and reversed process of these complexes in non-aqueous solutions.

The water gas shift (WGS) reaction catalyzed by bis(2,2?-bipyridine)carbonylruthenium(II) complexes under mild conditions (70-150C; 3-20 kg/cm2 of CO) has been investigated. Turnover numbers for the H2 formation of about 500 in 20 h have been obtained in an aqueous KOH solution containing [Ru-(bpy)2(CO)Cl](PF6) (bpy = 2,2?-bipyridine) as a catalyst precursor. The solvolysis of [Ru(bpy)2(CO)Cl]+ in an aqueous solution affords [Ru(bpy)2(CO)(H2O)]2+, which exists as an equilibrium mixture with [Ru(bpy)2(CO)(OH)]+ in a weak alkaline solution. Coordinated H2O of [Ru(bpy)2(CO)(H2O)]2+ is readily substituted by CO to produce [Ru(bpy)2(CO)2]2+, which undergoes a nucleophilic attack of OH- to afford [Ru(bpy)2(CO)C(O)OH]+. This hydroxycarbonyl complex not only exists as an equilibrium mixture with [Ru(bpy)2(CO)2]2+ and [Ru(bpy)2(CO)(COO-)]+ in alkaline media but also undergoes a decarboxylation reaction at elevated temperatures to give CO2 and [Ru(bpy)2(CO)H]+, which further reacts with H3O+ to evolve H2 and regenerate [Ru(bpy)2(CO)(H2O)]2+. All these species involved in the cycle of the WGS reaction catalyzed by [Ru(bpy)2(CO)Cl]+ have been isolated or characterized by spectrophotometry.

Two new ruthenium(II) complexes of formula [Ru(bpy)2-(L 1)][PF6] and [Ru(bpy)2(L2)][PF 6]2 are reported. HL1 is a (nitrophenyl) ethenyl-substituted phenylpyridine ligand, and L2 is the bipyridine analogue of HL1. The X-ray crystal structure of [Ru(bpy) 2(L1)][PF6] has been solved, and the compound is found to crystallize in the monoclinic C2/c space group. The electronic spectrum of the cyclometalated derivative [Ru(bpy)2(L 1)][PF6] exhibits a low-lying transition that is red-shifted from 454 to 546 nm relative to that of the parent bipyridine-based complex, which reveals an important charge-transfer character. To support this assumption, the nonlinear optical properties were investigated by the hyper-Rayleigh scattering technique and indicate a molecular static hyperpolarizability (beta0) equal to 230 × 10-30 cm5 esu-1.

The cis-[Ru(bpy)2(4-bzpy)(NO)](PF6)3 complex was prepared (4-bzpy = 4-benzoylpyridine), and characterized by UV-visible, infrared and nuclear magnetic resonance (NMR) spectroscopies and electrochemical techniques. The reaction with cysteine was preliminarily investigated, aiming to shed light on the potential biological mechanism for NO or HNO release mediated by thiols. Furthermore, photochemical behavior of cis-[Ru(bpy)2(4-bzpy)(NO)](PF6)3 was studied, where it was observed NO release upon ultraviolet, blue and green light irradiations. This latter long wavelength showed still good efficiency, which has not been reported for this type of complex. This feature is very important for a potential application in phototherapy. Additionally, vasorelaxant activity was investigated in rat-isolated aorta. This compound exhibited a greater maximum efficacy than sodium nitroprusside (SNP) as a blood vessel relaxant. Nevertheless, the EC50 for SNP (13.3 nmol L-1) was 52-fold smaller than the EC50 for cis-[Ru(bpy)2(4-bzpy)NO](PF6)3 (690 nmol L-1). Altogether, these results suggest this complex is a promising NO donor agent deserving further biological studies.
