title = "Oligomer-fullerene dyads : photophysics and performance as active layer material in photovoltaic cells",
abstract = "The photophysics of a homologous series of oligo(p-phenylene vinylene)-fulleropyrrolidine (OPVn-C60, n = 1 to 4, with n the no. of Ph rings) donor-acceptor dyads and the corresponding single moiety model compds. were studied. Fast intramol. singlet-energy transfer occurs after photoexcitation of the OPVn moiety in an apolar solvent. Photoexcitation in a polar solvent results in electron transfer for OPV3-C60, OPV4-C60, and to some extent for OPV2-C60, but not for OPV1-C60. These results are compared to the results obtained for mixts. of the single moiety model compds. in the same solvents. In these dyads electron transfer is likely to occur via a two-step process, i.e. a very fast singlet-energy transfer prior to charge sepn. In thin films of OPV3-C60 and OPV4-C60, a long-lived charge-sepd. state is formed after photoexcitation. This long lifetime is attributed to the migration of charges to different mols. A flexible photovoltaic device, prepd. from OPV4-C60, is presented.",
