Outline of Final Research Achievements

In order to construct efficient and extensible artificial systems capable of converting light energy to chemical potential, the introduction of flow system to the photochemical redox reaction systems using spherical bilayer membranes (vesicles) as reaction fields was examined. Although the flow system was successfully prepared according to the design, several problems arose in application of the flow system to the photochemical CO2 reduction in vesicular solutions, including fluctuation of CO2 concentration derived from feeding of the solution with a gear pump. The studies were also done to construct a vesicular system in which CO2 is reduced photochemically with high efficiency, and a construction of the visible-light-driven CO generation system using ascorbate as an electron donor in an aqueous vesicular solution was achieved.
