摘要

A donor-acceptor1-acceptor2 architectural 4-styryltriphenyl amine-based organic semiconductor was synthesized for solar cell applications. Sequential electron transfers together with effective hole transfer lead to a charge separated state lifetime of 650 ns, therefore boosting the short circuit current and efficiency of single layer organic photovoltaic cells.
