The properties of Ru II complexes involving the imidazole moiety are discussed. Complexes [Ru(bpy) 2 (L)] 2+ [bpy = 2,2 -bipyridine, L = 2-(2 -pyridyl)imidazole (2-pimH) and 4-(2 -pyridyl)imidazole (4-pimH)] have been synthesized and fully characterized. Reduction potentials are 0.76 V vs. Fc + /Fc
The temperature dependence of the emission lifetime of the series of complexes Ru(bpy),(4,4'-dpb): ? (bpy = 2,2'-bipyridine, 4,4'-dpb = 4,4'-diphenyL2,2'-bipyridine) has been studied in propionitrile/butyronitrile (4:5 u/u) solutions in the range 90-293 K. The obtained photophysical parameters show
