Ultrafast Energy And Electron Transfer In Conjugated Oligomer-Fullerene Molecules
Abstract The intramolecular photoinduced energy and electron transfer within a fullereneoligothiophene-fullerene triad with nine thiophene units ($ C_{60} $-9T-$ C_{60} $) and an oligo( p-phenylene vinylene)-fullerene dyad with four phenyl groups (OPV4-$ C_{60} $) is investigated with femtosecond pu...

| 520 | |a Abstract The intramolecular photoinduced energy and electron transfer within a fullereneoligothiophene-fullerene triad with nine thiophene units ($ C_{60} $-9T-$ C_{60} $) and an oligo( p-phenylene vinylene)-fullerene dyad with four phenyl groups (OPV4-$ C_{60} $) is investigated with femtosecond pump-probe spectroscopy with sub-10 fs and 200 fs time resolution in solvents of different polarity. Photoexcitation of the π-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 constant of 150-190 fs, irrespective of the polarity of the medium. In a polar solvent, intramolecular electron transfer occurs from the oligomer moiety to the $ C_{60} $ moiety with a time constant of 10-13 ps as a secondary reaction, subsequent to the ultrafast singlet-energy transfer. The charge-separated state has a lifetime of 50-80 ps and recombines to the ground state. | ||

Ultrafast Energy And Electron Transfer In Conjugated Oligomer-Fullerene Molecules |
| abstract |
Abstract The intramolecular photoinduced energy and electron transfer within a fullereneoligothiophene-fullerene triad with nine thiophene units ($ C_{60} $-9T-$ C_{60} $) and an oligo( p-phenylene vinylene)-fullerene dyad with four phenyl groups (OPV4-$ C_{60} $) is investigated with femtosecond pump-probe spectroscopy with sub-10 fs and 200 fs time resolution in solvents of different polarity. Photoexcitation of the π-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 constant of 150-190 fs, irrespective of the polarity of the medium. In a polar solvent, intramolecular electron transfer occurs from the oligomer moiety to the $ C_{60} $ moiety with a time constant of 10-13 ps as a secondary reaction, subsequent to the ultrafast singlet-energy transfer. The charge-separated state has a lifetime of 50-80 ps and recombines to the ground state. |
