The intramolecular photoinduced charge separation within an oligo(p-phenylene vinylene)–fulleropyrrolidine dyad with four phenyl rings (OPV4-C60) has been investigated with femtosecond pump-probe spectroscopy in solvents of different polarity and in the solid state. In solution, photoexcitation of the OPV4 moiety of OPV4-C60 results in an ultrafast (<190 fs) singlet energy transfer reaction, creating...
The intramolecular photoinduced energy and electron transfer in a fullerene-oligothiophene-fullerene triad with nine thiophene units (C 60 -9T-C 60 ) has been investigated with sub-10 fs pump-probe spectroscopy in solvents of different polarity. Photoexcitation of the oligothiophene moiety results in an ultrafast singlet-energy transfer reaction to create the fullerene singlet-excited...
