摘要: Fullerene coordination ligands bearing one bipyridine or terpyridine unit were synthesized, and their 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 the MLCT excited state. Time-resolved flash photolysis in CH 3 CN revealed characteristic transient absorption changes that have been ascribed formation C triplet state, suggesting photoexcitation (bpy-C results transduction state energy. The electrochemical studies on both [Ru(tpy)(tpy-C indicated electronic coupling between metal center fullerene core.
