Conjugated polymers have immense potential for their use as semiconducting materials in organic optoelectronic devices. The improvement of synthetic methods for conjugated polymers is important for the practical application of conjugated polymers. For mass production, synthetic methods must be developed by considering the concerns regarding cost and environment. Reduction in the number of synthetic steps is an efficient approach to address these concerns. The utilization of direct CH functionalization is a reasonable strategy in monomer and polymer syntheses, because the prefunctionalization steps for CC bond formation can be eliminated. This review summarizes the recent developments in the efficient syntheses of conjugated polymers as well as their monomers via direct arylation (CH/CX coupling) and cross-dehydrogenative coupling (CH/CH coupling) reactions.
共轭聚合物在有机光电设备中作为半导体材料具有巨大的应用潜力。改进共轭聚合物的合成方法对于共轭聚合物的实际应用非常重要。为了大规模生产，必须考虑成本和环境问题来开发合成方法。减少合成步骤的数量是解决这些问题的有效方法。在单体和聚合物合成中，直接 CH 功能化的利用是一种合理的策略，因为可以消除 CC 键形成的预官能化步骤。本综述总结了通过直接芳基化（CH/CX 偶联）和交叉脱氢偶联（CH/CH 偶联）反应高效合成共轭聚合物及其单体的最新进展。
