Abstract

Abstract Mixed-ligand complexes of 2,2′-bipyrazine (bpz), 2,2′-bipyridine (bpy), 2,3-di-(2′-pyridyl)-pyrazine (dpp), 2,3-dihydro-5,6-(2′-pyridyl)- pyrazine (dhp), 3,6-di-(2′-pyridyl)-1,2,4,5-tetrazine (dpt) and 2,3-di-(2′-pyridyl)-quinoxaline (dpq) with ruthenium(II), in addition to Ru(dhp) 3 2+, have been studied for evaluation as potential solar energy converters via an estimate of the redox potentials of their 3MLCT excited states. Cyclic voltammetry was used to show that bpz has lower σ-donor and higher π-acceptor abilities than the other ligands.
