Ruthenium and osmium complexes of 2,2′ : 6′,2″-terpyridine covalently linked to electron acceptor and electron donor groups

Abstract

2,2′ : 6′,2″-Terpyridine ligands have been modified so as to bear an electron acceptor or an electron donor group; efficient intramolecular vectorial electron transfer has been shown to occur in an osmium complex from its metal-to-ligand charge transfer excited state.
