Synthesis and Characteristics of Dinuclear Ruthenium(Ⅱ) Complexes with 2,2':6',2"-Terpyridine as the Ligand
Abstract:
The bisterpyridine ligands with oligo-PPV as spacer were designed and synthesized.Through step by step coordination,dinulear ruthenium complexes with terpyridine as the ligand were obtained.The complexes exhibited a strong metal to ligand charge transfer(MLCT) absorption peak at about 490 nm,while no emission was observed at ambient temperature because of the very short excited state time.All of the complexes,however,exhibited strong red emission (about 639~641 nm) at 77 K.The oxidation wave attributed to the ruthenium(Ⅱ) ion at about +1.25 V and the two reductive waves at about -1.15 V and(-1.38 V)(vs.Ag/AgCl) assigned to the terpyridine-based moiety were observed for the dinuclear ruthenium complexes.
