在聚合物主链中引入两个电子受体来构建“双受体”聚合物已被证明是开发高性能n型半导体聚合物的一种有效策略。这种“双受体”策略不仅可以改善聚合物的n型性能，还可以通过降低HOMO和LUMO能级来抑制聚合物的p型性质。

目前的大多数高性能“双受体”n型半导体聚合物都是通过传统的C（sp2）-C（sp2）-Stille偶联聚合法合成的。这种方法存在有机锡试剂官能团化之后的提纯很困难且其毒性较大，对环境很不友好，原子经济性差等缺点，这在很大程度上阻碍了此类半导体聚合物未来商业化应用的发展。C–H活化聚合即“直接芳基化聚合”（DArP）是替代Stille偶联的有力候补，具有环境友好、原子经济性高的特点，n型“双受体”聚合物的DArP聚合仍存在氢化受体单体有限等不足。

The introduction of two electronic receptors into the main chainof polymers to construct "double receptor" polymers has been provedto be an effective strategy for the development of high-performancen-type semiconductor polymers. This "double receptor" strategy cannot only improve the n-type properties of polymers, but alsoinhibit the p-type properties of polymers by reducing the HOMO andLUMO energy levels. However, most of the high-performance "doublereceptor" n-type semiconductor polymers reported at present aresynthesized by the traditional C (sp2) - C (sp2) - stille couplingpolymerization. 

This method has many disadvantages, such as difficultpurification after organotin reagent functionalization, hightoxicity, unfriendly to the environment, and poor atomic economy,which greatly hinders the development of commercial application ofthis kind of semiconductor polymer in the future. C – H activatedpolymerization, namely "direct arylation polymerization" (DArP), isa powerful alternative to Stille coupling, and has thecharacteristics of environmental friendliness and high atomiceconomy. However, the DArP polymerization of n-type "doublereceptor" polymers still has the disadvantages of limitedhydrogenated receptor monomers.
