In the current work, we present use of two free-base and zinc-metallated porphyrin-ruthenium(II) polypyridine dyads, along with reference porphyrin derivatives, as sensitizers in both n- p-type DSSCs DSPECs. Two dyads contain well-known Ru(bpy)3 unit (HOOC-DMP-Ru(bpy)3 HOOC-(Zn)DMP-Ru(bpy)3), while other terpyridine-Ru(Cl)-bypiridine was used (HOOC-DMP-tpy-Ru HOOC-(Zn)DMP-tpy-Ru). all systems, ...

Main-chain C,N-protected histidine has been successfully alkylated at both side-chain nitrogens. The corresponding histidinium salt was metallated with ruthenium(II) by a transmetalation procedure, thus providing histidine-derived NHC ruthenium complexes. These bio-inspired complexes show appreciable activity in the catalytic transfer hydrogenation of ketones.

Multinuclear ruthenium polypyridyl complexes are currently the subject of extensive investigations, their photophysical properties making them ideal components for photochemically and electrochemically driven molecular devices.1 Among these compounds, mononuclear ruthenium complexes containing biimidazole or bibenzimidazole (bibzimH2) type ligands2 have been shown to be excellent building block...

The synthesis and characterization of two dinuclear ruthenium polypyridyl complexes based on the bridging ligands 5,5'-bis(pyridin-2' '-yl)-3,3'-bis(1H-1,2,4-triazole) and 5,5'-bis(pyrazin-2' '-yl)-3,3'-bis(1H-1,2,4-triazole) and of their mononuclear precursors are reported. The dinuclear compounds have been prepared by a Ni(0) catalyzed coupling of a mononuclear ruthenium(II) polypyridyl compl...

Mono- and binuclear arene–ruthenium(II) complexes with imidazole-containing ligands were prepared by the reaction of (L1 = bis(imidazole-1-yl)methane; ImH 1H-Imidazole; BImH 1H-Benzimidazole) [(p-cym)Ru(µ-Cl)2]2 dimers. When bis(imidazole-1-yl)methane reacted in methanol, a complex type [Ru2(L1)2(p-cym)2Cl2]Cl2 (2) cyclic structure was synthesized, whereas using acetonitrile as solvent under sa...
