Conjugated single-layered two-dimensional covalent organic frameworks are flat and extended polymer networks with a unique combination of material properties, giving rise to potential applications in sensing, optoelectronics, and photonics. Despite their great potential, thus far only a few reactions to access such extended conjugated 2D polymers have been reported. Here, the on-surface polymerization of the first vinylene-linked single layered two-dimensional covalent organic framework using reversible Knoevenagel polycondensation under solvothermal conditions is described. Self-assembly of the two monomer building blocks at the solid−liquid interface led to the formation of extended covalent networks at room temperature without the need of additional catalysts or reagents. The described approach grants access to extended conjugated 2D polymers under unprecedentedly mild conditions and paves the way to new hybrid material systems.

亚乙烯基连接的单层共价有机框架的室温表面合成

共轭单层二维共价有机框架是平坦且延伸的聚合物网络，具有独特的材料特性组合，在传感、光电子学和光子学方面具有潜在的应用前景。尽管它们具有巨大的潜力，但迄今为止仅报道了少数获得这种扩展共轭二维聚合物的反应。在这里，描述了在溶剂热条件下使用可逆诺文格尔缩聚反应进行第一个亚乙烯基连接的单层二维共价有机骨架的表面聚合。两个单体构件在固液界面处的自组装导致在室温下形成扩展的共价网络，而不需要额外的催化剂或试剂。所描述的方法允许在前所未有的温和条件下获得扩展的共轭二维聚合物，并为新的混合材料系统铺平了道路。
