Covalent organic frameworks (COFs) are a class of crystalline porous organic polymers with polygonal porosity and highly ordered structures. The most prominent feature of the COFs is their excellent crystallinity and highly ordered modifiable one-dimensional pores. Since the first report of them in 2005, COFs with various structures were successfully synthesized and their applications in a wide range of fields including gas storage, pollution removal, catalysis, and optoelectronics explored. In the meantime, COFs also exhibited good performance in chemical and biological sensing, because their highly ordered modifiable pores allowed the selective adsorption of the analytes, and the interaction between the analytes and the COFs' skeletons may lead to a detectable change in the optical or electrical properties of the COFs. In this review, we firstly demonstrate the basic principles of COFs-based chemical and biological sensing, then briefly summarize the applications of COFs in sensing some substances of practical value, including some gases, ions, organic compounds, and biomolecules. Finally, we discuss the trends and the challenges of COFs-based chemical and biological sensing.
共价有机框架（COFs）是一类具有多边形孔隙和高度有序结构的结晶多孔有机聚合物。COFs 最显著的特点是其优异的结晶性和高度有序的可修饰一维孔道。自 2005 年首次报道以来，已成功合成了具有各种结构的 COFs，并探索了它们在气体储存、污染去除、催化和光电等广泛领域的应用。同时，COFs 在化学和生物传感方面也表现出良好的性能，因为其高度有序的可修饰孔道允许对分析物进行选择性吸附，并且分析物与 COFs 骨架之间的相互作用可能导致 COFs 的光学或电学性质发生可检测的变化。在这篇综述中，我们首先展示了基于 COFs 的化学和生物传感的基本原理，然后简要总结了 COFs 在传感一些具有实际价值的物质，包括一些气体、离子、有机化合物和生物分子方面的应用。最后，我们讨论了基于 COFs 的化学和生物传感的趋势和挑战。
