Exploring new building blocks for solution-processable polymeric semiconductors has attracted much attention. We herein develop two isomeric benzothiophene-flanked diketopyrrolopyrrole polymers with different linkage positions and further systematically study the electronic structures, optical properties, and field-effect characteristics. Both polymers exhibit typical p-type transport characteristics with the highest mobility being up to 0.80 cm2 V-1 s-1. Our results suggest that the isomeric backbones for conjugated polymers greatly affect charge transport properties. This study involved multiple reactions and reactants, such as Ethyl 5-bromobenzo[b]thiophene-2-carboxylate (cas: 13771-68-1Category: benzothiophene).
Ethyl 5-bromobenzo[b]thiophene-2-carboxylate (cas: 13771-68-1) belongs to benzothiophene derivatives. Benzothiophene is relatively a stable molecule. The electrophilic substitution of benzothiophene systems is much less regioselective than that of indoles. Its aromaticity makes it relatively stable, although as a heterocycle, it has reactive sites which allow for functionalization.Category: benzothiophene
