Abstract

Abstract Fullerene coordination ligands bearing one bipyridine or terpyridine unit were synthesized, and their coordination to ruthenium (II) formed linear rod-like donor–acceptor systems. Steady-state fluorescence of [Ru (bpy) 2 (bpy-C 60)] 2+ showed a rapid solvent- dependent, intramolecular quenching of the ruthenium (II) MLCT excited state. Time- resolved flash photolysis in CH 3 CN revealed characteristic transient absorption changes ...
