Outline of Final Research Achievements

In this study, design and development of complex with light-harvesting molecule, artificial co-enzyme and formate dehydrogenase for carbon dioxide fuelization were studied. The results are as follows.
(1) The suitable artificial co-enzyme for formate dehydrogenase was designed and synthesized. Relationship between the catalytic activity of formate dehydrogenase and chemical structure of artificial co-enzyme was clarified.
(2) The complex with light-harvesting molecule and artificial co-enzyme was was designed and synthesized. Photochemical and physical properties of the complex were clarified using fluorescence spectroscopy.
