Abstract

Covalent and well-defined oligomer-fullerene donor-acceptor mol. structures can serve as important model systems for plastic PV cells, based on interpenetrating networks of conjugated polymers and fullerene derivs. A series of fullerene-oligothiophene-fullerene triads with ter-, sexi- and novithienyl donor moieties and a homologous series of oligo[phenylenevinylene]-fullerene dyads were prepd. and investigated with respect to their photophys. properties such as photoinduced electron transfer using photoinduced absorption spectroscopy. Measurements on these novel structures both in soln. and in the solid state reveal that the environment plays a crucial role in the formation and lifetime of the various photoinduced charged states in these mols
