Outline of Final Research Achievements

In this study, we have paid attention to the biological function of the NAD+/NADH redox couple playing a crucial role as a generator and/or a reservoir of hydride ion in coenzyme NAD (Nicotinamide Adenine Dinucleotide) and developed photo-driven CO2 multi-reduction system by utilizing coordination compounds having the NAD function. As a result, we have got the following results; (1) we have found accelerating effect on the rate of CO2 reduction caused by the difference in the structural properties of the NADH model complexes derived from the methyl substituent group, (2) we have succeeded in control over the CO2 reduction rate by tuning of the basicity of the bases, (3) we have found novel synthetic method of NADH model complexes utilizing water-gas-shift-reaction condition.
