| Outline of Final Research Achievements |
Construction of artificial photosynthetic system with water as an electron donor has been studied on the stand point of learning nature and trying to exceed her even in a limited function. The structure of PSII in natural photosynthetic system has been investigated by means of X-ray diffraction study to succeed in revealing an intact structure without any damage under the extremely small X-ray dose conditions. A dynamic behavior of PSII in the transition of S2→S3 has been clearly observed by transient FT-IR spectroscopy to find an insertion process of water molecule into the PSII Kok cycle. Novel molecular catalyst for oxidation of water to form two-electron oxidation product, hydrogen peroxide, initiated by one-electron oxidation of the catalyst has been developed for the first time. Novel type of di-nuclear Ru(II) complex with high reactivity of water oxidation was synthesized.
