| Research Abstract |
In order to develop novel dinuclear complexes with coordination space for binding of carbon dioxide, a new bridging ligand, which includes a cyclohexane moiety as a spacer and two bipyridine groups as coordination sites, was synthesized. The reaction of the ligand with mononuclear ruthenium terpyridine complexes allowed the isolation of a dinuclear ruthenium complex. The dinuclear complex shows reversible redox properties originated from the ligand and ruthenium centers. In electrochemical measurements under CO2 conditions, catalytic currents was observed. Analyses by gas chromatography confirmed that CO was the only detectable gas phase product. These results show that flexibly bridged dinuclear ruthenium complexes can act as carbon dioxide reduction catalysts.
