  • Patent number: 8236967
    Abstract: A diindenothiophene derivative of the following formula (1) is disclosed: wherein each of G1, G2, G3 and G4 is independently an unsubstituted or substituted C6-C40-aromatic group or a C1-C40-aliphatic group; A is an electron-withdrawing group; and D is an electron-donating group. The inventive diindenothiophene derivatives can be used in a dye-sensitized solar cell.
