由于其多功能（光电）电子特性，共轭聚合物已在几种有机电子器件中得到应用。交叉偶联反应如Stille、Suzuki、Kumada偶联和直接芳化反应已被证明是有效的合成方法。原子效率更高的氧化直接芳基化聚合也被报道用于制备均聚物。然而，对供体-受体聚合物日益增长的兴趣导致了最近出现的交叉-脱氢偶联（CDC）聚合，以合成没有单体预官能化的交替共聚物。金属催化的通过双C−H活化的两个简单芳烃的交叉偶联，或通过氧化Heck型反应的芳烃与烯烃的交叉偶联，迄今已用于CDC聚合。在这篇文章中，我们讨论了CDC聚合协议的发展以及相关的小分子CDC反应，以提高对这些反应的理解。
Owing to their versatile (opto)electronic properties, conjugated polymers have found application in several organic electronic devices. Cross‐coupling reactions such as Stille, Suzuki, Kumada couplings, and direct arylation reactions have proved to be effective for their synthesis. More atom‐efficient oxidative direct arylation polymerization has also been reported for making homopolymers. However, growing interest toward donor‐acceptor polymers has led to the recent emergence of cross‐dehydrogenative coupling (CDC) polymerization to synthesize alternating copolymers without any prefunctionalization of monomers. Metal‐catalyzed cross‐coupling of two simple arenes via double C−H activation, or of an arene with an alkene via oxidative Heck‐type reaction have been used so far for CDC polymerization. In this article, we discuss the development of CDC polymerization protocols along with the relevant small molecule CDC reactions for an improved understanding of these reactions.
