Özet

© 2022For the preparation of conjugated polymers having targeted band gaps, absorption, and optoelectronic properties, the Donor-Acceptor (D-A) approach has been one of the most convenient methods. We synthesized four new conjugated polymers, bearing selenophene and thieno[3,4-c]pyrrole-4,6-dione (TPD) for this study via Suzuki Stille Polycondensation. The effect of selenophene that was inserted as π-bridge and the introduction of a second TPD unit into the polymer backbones through random polymerization were investigated. Optoelectronic properties of the polymers were analyzed via electrochemical and spectroelectrochemical studies. The study reveals the effects of TPD and selenophene moieties on absorption and band gaps of the polymer and provides a concise approach for the preparation of D-A conjugated polymers.
