Abstract

A novel distyryl BODIPY–fullerene dyad is prepared. Upon excitation at the distyryl BODIPY moiety, the dyad undergoes photoinduced electron transfer to give a charge-separated state with lifetimes of 476 ps and 730 ps in polar (benzonitrile) and nonpolar (toluene) solvents, respectively. Transient absorption measurements show the formation of the triplet excited state of distyryl BODIPY in the dyad, which is populated from charge-recombination processes in both solvents.

Charge separation: A novel distyryl BODIPY–fullerene dyad has been prepared (see figure) which, upon excitation at the distyryl BODIPY moiety, undergoes a facile photoinduced electron transfer to give a relatively long-lived charge-separated state.
