Extension of conjugated polymers from 1D to 2D can not only significantly enhance the dissociation of charge and excitons, but also induce other advantages, such as high in-plane mechanical strength, large specific surface area and porosity, and more active centers. 2D conjugated polymers can be divided into C-C bonded 2D polymers based on C-C coupling reactions, and heteroatomic bonded 2D polymers based on reversible heteroatom coupling reactions. C-C bonded 2D polymers are generally more stable than heteroatomic bonded 2D polymers as the latter bonds are easily hydrolyzed. This Review mainly summarizes C-C coupling reactions that are suitable for synthesizing 2D conjugated polymers, and the properties of these 2D conjugated polymers are also introduced.
将共轭聚合物从一维扩展到二维不仅可以显著增强电荷和激子的解离，还能带来其他优势，如高面内机械强度、大比表面积和孔隙率以及更多的活性中心。二维共轭聚合物可根据C-C偶联反应分为C-C键合二维聚合物，以及根据可逆杂原子偶联反应分为杂原子键合二维聚合物。由于后者的键容易水解，C-C键合二维聚合物通常比杂原子键合二维聚合物更稳定。本综述主要总结了适用于合成二维共轭聚合物的C-C偶联反应，并介绍了这些二维共轭聚合物的性质。
