| Outline of Final Research Achievements |
Lithium-ion-encapsulated fullerene (Li+@C60) ccould form strong supramolecular binding with various anionic electron donors via electrostatic interactions. Li+@C60 can also form strong supramolecular π-complexes with various electron donors such as cyclic porphyrin dimers, corannulene, and crown-ether-fused monopyrrolo-tetrathiafulvalenes. Photoinduced electron-transfer from electron donors to Li+@C60 afforded long-lived charge-separated states of supramolecular complexes between electron donors and Li+@C60. A photoelectrochemical solar cell composed of supramolecular nanoclusters of Li+@C60 and zinc sulfonated meso-tetraphenylporphyrin exhibits significant enhancement in the photoelectrochemical performance as compared with the reference system containing only a single component.
