Intermolecular resonant energy transfer of oligo(p-phenylenevinylene)–fullerene dyads: A theoretical study

Intermolecular resonant energy transfer (RET) of three different oligo(p-phenylenevinylene)–fullerene dyads (OPVn–MPC60; n = 2–4) has been studied by using semiempirical computational methods. Sub-picosecond intermolecular energy transfer comparable to intramolecular energy transfer has been found to take place in horizontal and vertical directions between adjacent dyads. The results do not rule out the possibility that energy transfer could precede charge separation in thin films made of OPVn–MPC60.
