| Outline of Final Research Achievements |
In this study, we investigated the following two themes to develop a photo charge-separation system that can be used for photo energy conversion. (1) By extending a two-dimensional square lattice, we have constructed a network structure in which fullerenes are densely packed in the pores. We tried to delay charge recombination by accepting electrons in the bands that form. (2) To investigate the delay of charge recombination by retarding the reverse electron transfer using the spin reversal due to the intersystem crossing, the porphyrin complexes containing heavy metal ions were co-crystallized with C60, and their crystal structures and absorption spectra were investigated.

光エネルギー変換が可能な光電荷分離システムを開発する視点から，電子アクセプターとしてC60を内包した六つのC60内包亜鉛ポルフィリンダイマーの開発を行い，ユニークな結晶構造をとることを明らかにするとともに光物性を調べた．このうちの一つの錯体を光レドックス触媒に用いて，実際に水素発生を示すことを明らかにした．さらに，C60を内包していない原料の亜鉛ポルフィリンダイマーでも水素発生が行えることも明らかにした．
