Περίληψη:
cis-[Ru(bpy)2(Ln)]Cl2 (n = 1, L 1 = 4-carboxy-2-(2′-pyridyl)quinoline (2); n = 2, L2 = 2,2′-pyridine-4,4′-dicarboxylic acid (4)); and cis-[Ru(bpy) 2(L′)2)]Cl2 (L′ = 4-pyridinecarboxylic acid (6)) complexes, with surface anchoring groups, are prepared from the reaction of cis-[Ru(bpy)2Cl2] (1) with the appropriate ligand (L1, L2, L′). Ion exchange in aqueous solution with NH4PF6 gives the corresponding bis(hexafluorophosphate) derivatives cis-[Ru(bpy)2(L 1)](PF6)2 (3), cis-[Ru(bpy)2(L 2)](PF6)2 (5) and cis-[Ru(bpy) 2(L′)2](PF6)2 (7), respectively. The photo-electrochemical properties of the dyes (2-7) are investigated and the efficiency of the corresponding dye sensitized solar cells is compared to a N719 sensitized device, under similar fabrication and testing conditions. © The Royal Society of Chemistry and Owner Societies 2009.
