3,4-Appended thiophene monomers furnish unique optoelectronic properties due to electronic and steric effects on the donor unit. Here, we have demonstrated a new polymer synthesis by direct arylation polycondensation of 9,10-dihydro-9,10-[3,4]thiophenoanthracene, a thiophene-based monomer. Chloride-promoted direct arylation polycondensation of 9,10-dihydro-9,10-[3,4]thiophenoanthracene with dibromo monomers with acetate in N,N-dimethylacetamide gave conjugated alternating copolymers. The obtained polymer had a molecular weight of 38,000 and exhibited high film-forming ability. The optical and electrochemical properties of the polymers were also discussed.
