π-Conjugated polymers are widely used in optoelectronics for fabrication of organic photovoltaic devices, organic light-emitting diodes, organic field effect transistors, and so on. Here we describe the protocol for polycondensation of bifunctional aryl ethers or aryl ammonium salts with aromatic dimetallic compounds through cleavage of inert C-O/C-N bonds. This reaction proceeds smoothly in the presence of commercially available Ni/Pd catalyst under mild conditions, affording the corresponding π-conjugated polymers with high molecular weight. The method is applicable to monomers that are unreactive in other currently employed polymerization procedures, and opens up the possibility of transforming a range of naturally abundant chemicals into useful functional compounds/polymers.
π 共轭聚合物在光电领域被广泛应用于制备有机光伏器件、有机发光二极管、有机场效应晶体管等。在这里，我们描述了通过断裂惰性 C-O/C-N 键，使双官能芳基醚或芳基铵盐与芳族二金属化合物缩聚的方法。该反应在市售的 Ni/Pd 催化剂存在下，于温和条件下顺利进行，得到了相应的具有高分子量的 π 共轭聚合物。该方法适用于在其他现有聚合方法中不反应的单体，为将一系列丰富的天然化学品转化为有用的功能化合物/聚合物开辟了可能性。
