To attaining longlived charge separated states, the new compounds 7 and 8 of C60-S-2-thioxo-1, 3-dithioles derivatives were synthesized by Diels-Alder cycloaddition reaction. The structures generated by AM1 were used as the initial configurations for the density functional optimization at the B3LYP/3-21G level for all carbon and sulfur clusters, and some geometry conformation indexes were obtained. We found that C60 has been half-packed by the curved 2-thioxo-1, 3-dithioles derivatives.
