| Research Abstract |
Various transition-metal complexes containing visible-light absorbing Ru(II) polypyridyl moiety have been synthesized. Systematic studies on the catalytic activities of the Ru-Pd catalysts revealed that the introduction of electron donating group on the bipyridyl ligands and the electron withdrawing group on the bridging ligand led to the drastic rate acceleration. The origin of the acceleration is most probably due to the expansion of energy gap between the LUMO+1 and LUMO orbitals which lead to the preferencial MLCT toward the bridging ligand.
