Adsorption spectroscopy and transient emission spectroscopy were used to follow intramolecular electron transfer quenching after metal-to-ligand charge transfer (MLCT) excitation of Ru(II)bipyridine-quinone complexes. Studies of various N-((4{prime}methyl-2-2{prime}-bipyridyl)-4-methyl)-9,10-anthraquinone-2-carboxamide (bpy-AQ) complexes, revealed that these complexes quench by rapid electron transfer from ligand radical excited states to the metal center. A donor-chromophore-acceptor complex with the bpy-AQ ligand and the (10-[4({prime}-methyl-2,2{prime}-bipyridin-4-yl)methylphenothiazine)] (bpy-PTZ) ligand displays redox separation on excitation.
