| Outline of Final Research Achievements |
We demonstrated that under visible light (> 400 nm) irradiation, CO2 was converted into CO and HCO2H using transition metal complexes bearing Ir, Ru or Co as a metal center coordinated with (P,N,N,P)-type tetradentate ligands. The highest turnover number recorded is around 20. It was also revealed that structural robustness (no decomposition of metal complex during light irradiation) should be more improved to ensure a higher TON. Direct conversion of CO2 to MeOH would be also possible in a future development of a higher performance molecular catalyst bearing a tetradentate ligand.
