| Outline of Final Research Achievements |
The reaction mechanism of the photoexcited states of supramolecular complexes composed of self-assembling pyridyl-substituted cyclic porphyrin dimers and fullerenes was analyzed to show the formation of charge-separated states that have very long lifetimes (0.7 ms). The photovoltaic properties of dye-sensitized solar cells that employ the inclusion complex of the porphyrins and C60 fixed on thin film of TiO2 were evaluated to confirm the high adsorption amount of the complexes due to the effect of the multi-pyridyl anchoring groups and the better performance of the cyclic porphyrin dimers than the complxes. The quantum yield and rate of singlet oxygen generation by the photoexcitation of the supramolecular complexes of the cyclic porphyrin dimers with C60 were determined to clarify the higher activity of the the cyclic porphyrin dimers than the complxes.
