Thiophene with an oligoethylene oxide side chain (TOE) was introduced into a D-A copolymer acceptor, as the third unit, by simple random polymerization. A moderate amount of TOE loading does not only modulate the polymer-acceptor solubility and molecule arrangement, but also improves the compatibility between the polymer donor and acceptor.

具有低聚环氧乙烷侧链的噻吩使随机三元共聚物受体能够实现高效的全聚合物太阳能电池

通过简单的无规聚合，将具有低聚环氧乙烷侧链 (TOE) 的噻吩作为第三个单元引入到 DA 共聚物受体中。适量的 TOE 负载量不仅可以调节聚合物-受体的溶解度和分子排列，还可以改善聚合物供体和受体之间的相容性。
