In (5)(PF6)2-(7)(PF6) 2, the nucleobase 9MeG binds to ruthenium through N7. Based on 1H NMR spectroscopy, a strong shielding effect between the aromatic ring system of the quinoxaline or benzo[g]quinoxaline moiety of the ligands pqx and pbqx and the H8 of 9MeG was observed. The complexes (1)-(4) are highly cytotoxic as chloride salts, against various cancer cell lines, with their IC50 values observed at less than 1 muMu.

This paper describes effective photocurrent generation based on a polymer Langmuir-Blodgett (LB) monolayer containing ruthenium complex on a silver electrode excited by surface plasmon resonance (SPR). It was found that photocurrent generation is greatly enhanced at an incident angle where the electromagnetic field was most enhanced by SPR. At this angle, the photocurrent is enhanced by a factor of 23.6 compared with that at the critical angle for total internal reflection. The incident monochromatic photon-to-current conversion efficiency was 9.53*10-3 percent, higher than that of the corresponding polymer LB monolayer film on a transparent indium tin oxide electrode with conventional direct transmitted light (2.87*10-3 percent). Furthermore, it was demonstrated that precoating with poly(N-decylacrylamide) homopolymer ensures adequate separation of the Ru (bpy)3(2+) and silver surface, thereby suppressing the quenching of photoexcited Ru(bpy)3(2+) by the silver. Controlling the distance between the Ru(bpy)3(2+) layer and the silver using the Langmuir-Blodgett technique leads to effective photoexcitation of Ru(bpy)3(2+) by SPR and suppression of quenching by the silver surface, resulting in efficient photocurrent generation.

The reaction of various pyridine-2-carboxaldimine ligands with the [(eta6-arene)Ru(mu-Cl)Cl]2 dimer followed by a metathesis reaction with ammonium hexaflourophosphate, yielded the ruthenium(II) arene complex salts [(eta6-arene)RuCl(C5H4[Formula presented]6; where (arene = C6H6 (1), p-cymene (2), Ar = 3, 5-dimethyl phenyl (a), 2,3-dimethyl phenyl (b), 2,5-dimethyl phenyl (c), 3,4-dimethyl phenyl (d)). The compounds were characterized by elemental analysis, FT- IR, UV?vis and 1H and 13C NMR. Single crystal X-ray structures for compounds 1a, 1d and 2e were also determined and showed that the ruthenium(II) centre has a pseudo-octahedral geometry and the molecule adopted a three legged piano stool geometry in which the arene ring occupies the apex and the nitrogen atoms of the N,N?-bidentate ligand and the chloride atom the base of the stool. The Ru(II) complex salts were active for the catalytic transfer hydrogenation of ketones into alcohols in the presence of NaOH using 2-propanol as the hydrogen source at 82 C. The complexes were suitable for a wide range of aliphatic, cyclic and aromatic ketones giving good turn over numbers.

The complexes TpRu[P(OCH2)2(OCCH3] (PPh3)Cl (2) [Tp = hydridotris(pyrazolyl)borate; P(OCH 2)2(OCCH3) (1) = (4-methyl-2,6,7-trioxa-1- phosphabicyclo[2,2,1]heptane] and TpRu(L)(PPh3)Cl [L = P(OCH 2)3CEt (3), PMe3 (4) or P(OMe)3 (5)], (eta6-C6H6)Ru(L)Cl2 [L = PPh3 (6), P(OMe)3 (7), PMe3 (8), P(OCH 2)3CEt (9), CO (10) or P(OCH2) 2(OCCH3) (11)] and (eta6-p-cymene)Ru(L) Cl2 [L = P(OCH2)3CEt (12), P(OCH 2)2(OCCH3)P(OCH2) 2(OCCH3) (13), P(OMe)3 (14) or PPh3 (15)] have been synthesized, isolated, and characterized by NMR spectroscopy, cyclic voltammetry, mass spectrometry, and, for some complexes, single crystal X-ray diffraction. Data from cyclic voltammetry and solid-state structures have been used to compare the properties of (1) with other phosphorus-based ligands as well as carbon monoxide. Data from the solid-state structures of Ru(II) complexes show that P(OCH2)2(OCCH3) has a cone angle of 104. Cyclic voltammetry data reveal that the Ru(II) complexes bearing P(OCH2)2(OCCH3) have more positive Ru(III/II) redox potentials than analogous complexes with the other phosphorus ligands; however, the Ru(III/II) potential for (eta6-C 6H6)Ru[P(OCH2)2(OCCH 3)]Cl2 is more negative compared to the Ru(III/II) potential for the CO complex (eta6-C6H 6)Ru(CO)Cl2. For the Ru(II) complexes studied herein, these data are consistent with the overall donor ability of 1 being less than other common phosphines (e.g., PMe3 or PPh3) or phosphites [e.g., P(OCH2)3CEt or P(OMe)3] but greater than carbon monoxide.

Porphyrins are used as photosensitizing agents in photodynamic therapy (PDT) for several pathologies. Here we demonstrate the DNA photocleavage and cytotoxicity properties of a free-base meso-tetra-ruthenated porphyrin (H2RuTPyP) in purified DNA samples and in a melanoma cell line, respectively. Cytotoxicity of H2RuTPyP was investigated by the tetrazolium dye (MTT) colorimetric assay and its genotoxic potential by direct plasmid DNA photocleavage after incubation with specific DNA repair enzymes. H2RuTPyP porphyrin efficiently induced DNA damage at the lower concentration of 5.0 muM, whereas it induced complete DNA degradation at 15 muM. The addition of different scavengers for reactive oxygen species (ROS) during the visible light exposures did not decrease the DNA damage formation, suggesting a hydrolytic mechanism for the induction of DNA breaks. Also, H2RuTPyP exhibited a much higher cytotoxicity in melanoma cells in comparison to a keratinocyte cell line. The detection of intracellular reactive oxygen species (ROS) produced by H2RuTPyP through the DCF-DA assay also suggests that ROS have a minor role in the induction of cytotoxicity. Therefore, H2RuTPyP seems to be a very effective photosensitizer, representing a promising alternative for the development of new skin cancer treatments using PDT process.

New Ruthenium complexes I, II and III were synthesized using 5-chlorothiophene-2-carboxylic acid (5TPC), as ligand and the complexes were characterized by elemental analysis, FT-IR, 1H, 13C NMR, and mass spectroscopic techniques. Photophysical and electrochemical studies were carried out and the structures of the synthesized complex were optimized using density functional theory (DFT). The molecular geometry, the highest occupied molecular orbital (HOMO), the lowest unoccupied molecular orbital (LUMO) energies and Mulliken atomic charges of the molecules are determined at the B3LYP method and standard 6-311++G (d,p) basis set starting from optimized geometry. They possess excellent stabilities and their thermal decomposition temperatures are 185 C, 180 C and 200 C respectively, indicating that the metal complexes are suitable for the fabrication processes of optoelectronic devices.

The bis(oxazoline) ligand, 2,2-bis[4(R)-phenyl-1,3-oxazolon-2-yl]propane (bpop), was introduced to the eta6-benzeneruthenium(II) moiety on treatment with [Ru(eta6-C6H6)Cl2]2 to give [Ru(eta6-C6H6) (bpop)Cl]+. Aquo and amine complexes [Ru(eta6-C6H6) (bpop) (L)]2+ (L=H2O (1), NH2R; R=H (2), Me (3), and n-Bu (4)) were prepared by treating the chloride complex with AgBF4 in the presence of L. X-ray structure determinations of 1 and 3 were carried out. Both complexes possessed a three-leg piano stool structure with the N or O donors located at the three corners of a pseudo octahedron. The aquo complex 1 exhibited a dynamic NMR feature in which two magnetically non-equivalent oxazoline parts observed at lower temperatures were interchanged with each other at higher temperatures. This observation was ascribed to the formation of a C2-symmetric 16-electron intermediate via Ru-OH2 cleavage, which is slower in acetone than in dichloromethane owing to more effective solvation by acetone around hydrogens of the coordinated water molecule. The two diastereotopic N-hydrogens of 4 underwent deuterium exchange with CD3OD with greatly different rates from each other owing to different energy of NH…O(D)(CD3) interaction. Carboxylate and sulfonate ions (A-) formed second sphere complexes with 4 by means of NH…A- hydrogen bonding, as evidenced by continuous shift of NH2 resonances with increasing amounts of the anions added.

Ru(ii) complexes of TsDPEN containing two alkyl groups on the non-tosylated nitrogen atom are poor catalysts for asymmetric transfer hydrogenation of ketones and imines; this observation provides direct evidence for the importance of the N-H interaction in the transition state for ketone reduction.

Application of 15746-57-3, An article , which mentions 15746-57-3, molecular formula is C20H16Cl2N4Ru. The compound – Cis-Dichlorobis(2,2′-bipyridine)ruthenium(II) played an important role in people’s production and life.

Electronic and photophysical characterization is presented for a series of bis-heteroleptic [Ru(bpy)2(R-CAQN)]+ complexes where CAQN is a bidentate N-(carboxyaryl)amidoquinolate ligand and the aryl substituent R = p-tolyl, p-fluorobenzene, p-trifluoromethylbenzene, 3,5-bis(trifluoromethyl)benzene, or 4-methoxy-2,3,5,6-tetrafluorobenzene. Characterized by a strong noninnocent Ru(dpi)-CAQN(pi) bonding interaction, density functional theory (DFT) analysis is used to estimate the contribution of both atomic Ru(dpi) and ligand CAQN(pi) manifolds to the frontier molecular orbitals of these complexes. UV-vis absorption and emission studies are presented where the noninnocent Ru(dpi)-CAQN(pi) bonding scheme plays a major role in defining complex electronic and photophysical properties. Oxidation potentials are tuned over a range of 0.92 V with respect to the [Ru(bpy)3]2+ reference system, hereafter referred to as 12+, by varying the degree of R-CAQN fluorination while maintaining consistently strong and panchromatic visible absorption properties. Electron paramagnetic resonance (EPR) spectroscopy is employed to experimentally map delocalization of the unpaired electron/electron-hole within the delocalized Ru(dpi)-CAQN(pi) singly occupied valence molecular orbital of the one-electron oxidized complexes. EPR data is complemented experimentally by UV-vis-NIR spectroelectrochemistry, and computationally by molecular orbital Mulliken contributions and spin-density analysis. It is ultimately demonstrated that the CAQN ligand framework provides a simple yet broad synthetic platform in the design of redox-active transition metal chromophores with a range of electronic and spectroscopic characteristics hinting at the diversity and potential of these complexes toward photochemical and catalytic applications.
