| Outline of Final Research Achievements |
Molecular wire－Pt nanoparticle(PtNP) unit for PSI has been newly developed. This molecular wire can be exchanged with vitamin K1 in the quinone pocket of photosystem I (PSI). Similarly, molecular wire－PtNP unit for PSII was newly developed. PSI and PSII were reconstituted with these units. Photoinduced hydrogen evolution occurred with PSI-molecular wire－PtNP using sacrificial reagent. The molecular wire －PtNP unit was successfully introduced to PSII, however, Mn cluster was removed from PSII in the reconstitution process. In the achievement of water-splitting reaction with PSII-molecular wire－PtNP, reconstitution of the Mn cluster will be necessary.
