Photoelectronic Properties of Thiophene-Vinylene Derivatives with Phthalimide Groups in Both Terminals

Abstract

We synthesized two novel thiophene-vinylene derivatives with phthalimide groups in both terminals. Thiophene-vinylene skeleton was effective to increase IP and to decrease optical band gap, meanwhile, introduction of phthalimide groups lowered ionization potential value (IP), meanwhile, thiophene-vinylene was effective to increase IP and to decrease optical band gap.
