    Abstract

    Optical properties and photoconduction of the composites of poly(3-octylthiophene) (PAT-8) and novel C60 derivatives, tetra(amino)fullerene epoxides (TAFEs) have been studied. TAFEs have high solubility, so heavy doping into conducting polymers is possible in the wet process. PL intensity of PAT-8 has been quenched and photocurrent intensity has been enhanced markedly with increasing the concentration of TAFEs, which can be explained as being due to the photoinduced charge transfer from PAT-8 to TAFEs. In the case of heavy doping of TAFEs into PAT-8, spectral changes in absorption and photoconduction spectra have been observed, which can be interpreted as being due to the charge transfer from PAT-8 to TAFEs in the ground state.
