In the past decade, direct arylation polymerization (DArP) has rapidly developed as a sustainable synthetic protocol for cost-effective, atom-economical preparation of conjugated polymers. By circumventing monomer functionalization with toxic transmetallating reagents such as organostannane and organoboron required for Stille-Migita and Suzuki-Miyaura polymerization methods, DArP proceeds through a metal-catalyzed CH activation pathway for the preparation of high-performance conjugated polymer materials. This review evaluates the development of several classes of efficient catalysts/catalytic systems from small-molecule studies to polymerizations, including the mechanisms involved in these transformations and how they inspire catalyst and monomer design for defect-free conjugated polymer synthesis. Recent advances in developing more sustainable first-row transition metal catalysts for DArP are also highlighted, and the fundamental understanding of these efficient and sustainable catalysts should motivate the pursuit for the next generation of catalytic design to enable more effective and environmentally friendly conjugated polymer synthesis.

提高直接芳基化聚合 (DArP) 催化剂的效率和可持续性

在过去十年中，直接芳基化聚合 (DArP) 已迅速发展成为一种可持续的合成方案，用于经济高效、原子经济地制备共轭聚合物。通过使用 Stille-Migita 和 Suzuki-Miyaura 聚合方法所需的有毒金属转移试剂（如有机锡烷和有机硼）规避单体官能化，DArP 通过金属催化的 C H活化途径制备高性能共轭聚合物材料。本综述评估了从小分子研究到聚合的几类高效催化剂/催化系统的开发，包括这些转化所涉及的机制，以及它们如何激发催化剂和单体设计以实现无缺陷共轭聚合物合成。还强调了在为 DArP 开发更可持续的第一行过渡金属催化剂方面的最新进展，对这些高效和可持续催化剂的基本理解应该会激发对下一代催化设计的追求，以实现更有效和环保的共轭聚合物合成。
