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.

通过直接芳基化缩聚制备基于噻吩蒽的共轭聚合物

由于给体单元上的电子和空间效应，3,4-附加噻吩单体提供了独特的光电特性。在这里，我们展示了一种通过 9,10-二氢-9,10-[3,4]噻吩蒽（一种基于噻吩的单体）直接芳基化缩聚合成的新聚合物。 9,10-二氢-9,10-[3,4]噻吩蒽与二溴单体与乙酸酯在N,N-二甲基乙酰胺中进行氯化物促进的直接芳基化缩聚反应，得到共轭交替共聚物。所得聚合物的分子量为38,000，表现出高成膜能力。还讨论了聚合物的光学和电化学性质。
