Abstract
Bislactone linked porphyrin-fullerene dyads show promising photophysical properties for mimicking photosynthesis. Optical and transient displacement current investigations of the dyads demonstrate efficient intramolecular electron transfer from porphyrin to fullerene with the lifetime of the charge transfer state on the order of a few nanoseconds in low polarity solvents. Solvent polarity effect on the yield of charge separation and conformations in the charge transfer state are investigated in detail. The facile synthesis could readily be applied to constructing extended compounds with high yields of photoinduced charge separation.
