摘要
As typical representative of porous crystalline polymers, covalent organic frameworks (COFs) based on dynamic covalent chemistry and topological design are constructed with organic units via covalent bond. Their unique properties such as high stability, accessible functionality, ordered porosity, and predesignable structure make COFs highly promising in environmental analysis. This review highlights the state-of-the-art design and modification of COFs in terms of functionality, stability and pore to meet the requirements of environmental analysis, as well as the mechanism and application of the COFs for the adsorption/removal, separation and sensing of various environmental contaminants. In addition, the challenge and future direction of COFs in environmental analysis are outlooked for the further research. (c) 2022 Elsevier B.V. All rights reserved.
