摘要：
The synthesis, complete spectroscopic characterization, cyclic voltammetry, and photophysical measurements of a new omicron-phenylenediamine C-60 dyad are described. By using a tether strategy, only a single regioisomer was obtained. Cyclic voltammetry measurements indicate that the two electroactive groups do not interact in their singlet ground states. Photophysical investigations reveal a rapid photoinduced electron transfer between the singlet excited state of the fullerene acceptor and the omicron-phenylenediamine donor, yielding a charge-separated radical pair.
