摘要

A brief overview of our group research activities is given and the concept of donor-acceptor is described for the development of conjugated polymers for optoelectronic devices. In particular, a new family of conjugated polymers based on dithienopyrrole has been synthesized to demonstrate the concept of donor-acceptor. The dithienopyrrole was coupled to benzo-dithiophene via Stille coupling to obtain two low band gap polymers P5a and P5b having -Ci8H37 and -2-ethyl-hexyl alkyl chain respectively. Boththe polymers exhibit absorption within the solar spectrum with an optical band gap below 2 eV. Atomic force microscopy revealed that both the polymers form smooth film with roughness of 2.4 nm and photoluminescence measurement of polymer/fullerene derivative blend film suggests effective dissociation of exciton.
