摘要：

We report here on one of the rare cases that realizes a reductive charge shift from a primary electron acceptor (C(60)) to a secondary electron acceptor (C(70)) in a ZnP-C(60)-C(70) conjugate. Initially, charge separation evolves from an excited state electron donor (ZnP). By far the most far reaching benefit from such a reductive pathway is a marked slow down of the energy wasting charge recombination when compared to the ZnP-C(60) conjugate (i.e., picoseconds versus nanoseconds).
