Abstract

Covalent organic frameworks (COFs) are crystalline porous polymeric materials composed of organic monomers connected by strong covalent bonds and offer high stability, good crystallinity, a large specific surface area, and controllable structures. COFs are widely used in the fields of adsorption and separation, catalysis, photovoltaics, and drug-delivery. The structural regulation and performance optimization of COFs can be realized through the modification of ligands and the selection of linkage methods. In which, the types of linkage are closely related to the stability and performance of COFs. In this review, nitrogen-containing linkage-bonds (NCLBs) in COFs are divided into N-containing double bonds, N-containing conjugated rings and N-containing unconjugated rings. The association between structure and performance of COFs is elaborated and the synthesis methods of COFs are systematically summarized. Moreover, the structural design, theoretical prediction and machinable application of COFs are prospected

共价有机框架中的含氮连接键：合成与应用

共价有机框架（COFs）是由有机单体通过强共价键连接而成的结晶多孔高分子材料，具有高稳定性、良好的结晶度、大的比表面积和可控的结构。COFs在吸附分离、催化、光伏、给药等领域有着广泛的应用。通过配体的修饰和连接方式的选择，可以实现COFs的结构调控和性能优化。其中，连杆的类型与COFs的稳定性和性能密切相关。本文将COFs中的含氮键（NCLBs）分为含n双键、含n共轭环和含n非共轭环。阐述了COFs的结构与性能之间的关系，系统总结了COFs的合成方法。展望了COFs的结构设计、理论预测和可加工应用
