The ability of the doublet excited state of perylene diimide anion radical (2)(PDI-center dot)* to reduce aromatic electron acceptors was probed by picosecond time-resolved transient absorption (TA) spectroscopy. Excitation of PDI-center dot produces visible TA due to (2)(PDI-center dot)* that decays with tau = 160 ps. Aromatic electron acceptors with varying reduction potential quench (2)(PDI-center dot)* and, in some cases, give a new visible region absorption that is attributed to the products of bimolecular photoinduced electron transfer, (2)(PDI-center dot)* + Ar-X -> PDI + Ar-X-center dot. Stern-Volmer quenching of (2)(PDI-center dot)* accomplished with a series of acceptors provides bimolecular quenching rate constants as a function of acceptor reduction potential. Rehm-Weller analysis of the electron transfer quenching data affords the potential for the (*PDI-center dot/PDI) electrochemical half-reaction as -1.87 V vs SCE.
