Covalent organic frameworks (COFs) have gained considerable attention due to their design possibilities as the molecular organic building blocks that can stack in an atomically precise spatial arrangement. Since the inception of COFs in 2005, there has been a continuous expansion in the product range of COFs and their derivatives. This expansion has led to the evolution of three-dimensional structures and various synthetic routes, propelling the field towards large-scale preparation of COFs and their derivatives. This review will offer a holistic analysis and comparison of the spatial structure and synthesis techniques of COFs and their derivatives. The conventional methods of COF synthesis (, ultrasonic chemical, microwave, and solvothermal) are discussed alongside the synthesis strategies of new COFs and their derivatives. Furthermore, the applications of COFs and their derived materials are demonstrated in air, water, and soil pollution management such as gas capture, catalytic conversion, adsorption, and pollutant removal. Finally, this review highlights the current challenges and prospects for large-scale preparation and application of new COFs and the derived materials. In line with the United Nations Sustainable Development Goals (SDGs) and the needs of digital-enabled technologies (AI and machine learning), this review will encompass the future technical trends for COFs in environmental pollution control.
共价有机框架（COFs）因其作为分子有机构建块的设计可能性而备受关注，这些构建块可以以原子精确的空间排列方式堆叠。自2005年COFs诞生以来，COFs及其衍生物的产品范围不断扩大。这种扩展导致了三维结构和各种合成路线的演变，推动该领域朝着COFs及其衍生物的大规模制备发展。本综述将对COFs及其衍生物的空间结构和合成技术进行全面分析和比较。讨论了COF合成的传统方法（如超声化学法、微波法和溶剂热法）以及新型COFs及其衍生物的合成策略。此外，还展示了COFs及其衍生材料在空气、水和土壤污染管理中的应用，如气体捕获、催化转化、吸附和污染物去除。最后，本综述强调了新型COFs及其衍生材料大规模制备和应用面临的当前挑战和前景。根据联合国可持续发展目标（SDGs）以及数字赋能技术（人工智能和机器学习）的需求，本综述将涵盖COFs在环境污染控制方面的未来技术趋势。
