Abstract
Two types of dyads having different modes of attachment i.e. cyclopropanation vs. pyrrolidine type in porphyrin–fullerene linked systems are compared for their photophysical properties. Dyad II with pyrrolidine type of linkage shows faster charge separation and generation of long lived charge separated states. It also shows a new property of thermally activated electrical conductivity which makes it potential candidate for organic electronic devices.
