Covalent organic frameworks (COFs) are a class of crystalline porous organic polymers with permanent porosity and highly ordered structures. Unlike other polymers, a significant feature of COFs is that they are structurally predesignable, synthetically controllable, and functionally manageable. In principle, the topological design diagram offers geometric guidance for the structural tiling of extended porous polygons, and the polycondensation reactions provide synthetic ways to construct the predesigned primary and high-order structures. Progress over the past decade in the chemistry of these two aspects undoubtedly established the base of the COF field. By virtue of the availability of organic units and the diversity of topologies and linkages, COFs have emerged as a new field of organic materials that offer a powerful molecular platform for complex structural design and tailor-made functional development. Here we target a comprehensive review of the COF field, provide a historic overview of the chemistry of the COF field, survey the advances in the topology design and synthetic reactions, illustrate the structural features and diversities, scrutinize the development and potential of various functions through elucidating structure–function correlations based on interactions with photons, electrons, holes, spins, ions, and molecules, discuss the key fundamental and challenging issues that need to be addressed, and predict the future directions from chemistry, physics, and materials perspectives.

共价有机框架：设计，合成和功能。

共价有机骨架（COF）是一类具有永久孔隙度和高度有序结构的结晶多孔有机聚合物。与其他聚合物不同，COF的显着特征是它们在结构上是可预先设计的，可综合控制的和在功能上可控制的。原则上，拓扑设计图为扩展的多孔多边形的结构平铺提供几何指导，缩聚反应提供了构建预先设计的一级和高级结构的综合方法。过去十年中在这两个方面的化学进展无疑为COF领域奠定了基础。由于有机单位的可用性以及拓扑和链接的多样性，COF已成为有机材料的新领域，为复杂的结构设计和量身定制的功能开发提供了强大的分子平台。在这里，我们针对COF领域进行全面审查，对COF领域的化学性质进行历史性概述，调查拓扑设计和合成反应的进展，说明结构特征和多样性，通过以下方式仔细研究各种功能的发展和潜力阐明基于与光子，电子，空穴，自旋，离子和分子的相互作用的结构与功能的相关性，讨论需要解决的关键基本和挑战性问题，并从化学，物理和材料的角度预测未来的方向。
