title = "Ultrafast energy and electron transfer in conjugated oligomer-fullerene molecules",
abstract = "The intramol. photoinduced energy and electron transfer within a fullerene-oligothiophene-fullerene triad with nine thiophene units (C60-9T-C60) and an oligo(p-phenylene vinylene)-fullerene dyad with four Ph groups (OPV4-C60) was studied with femtosecond pump-probe spectroscopy with sub-10 fs and 200 fs time resoln. in solvents of different polarity. Photoexcitation of the p-conjugated oligomer moiety in the triad and dyad results in an ultrafast singlet-energy transfer reaction to create the fullerene singlet-excited state with a time const. of 150-190 fs, irresp. of the polarity of the medium. In a polar solvent, intramol. electron transfer occurs from the oligomer moiety to the C60 moiety with a time const. of 10-13 ps as a secondary reaction, subsequent to the ultrafast singlet-energy transfer. The charge-sepd. state has a lifetime of 50-80 ps and recombines to the ground state. [on SciFinder (R)]",
