The effective capture and storage of volatile molecular iodine from nuclear waste is of great significance. Covalent organic frameworks (COFs) are a class of extended crystalline porous polymers that possess unique architectures with high surface areas, long-range order, and permanent porosity. Substantial efforts have been devoted to the design and synthesis of COF materials for the capture of radioactive iodine. In this review, we first introduce research techniques for determining the mechanism of iodine capture by COF materials. Then, the influencing factors of iodine capture performance are classified, and the design principles and strategies for constructing COFs with potential for iodine capture are summarized on this basis. Finally, our personal insights on remaining challenges and future trends are outlined, in order to bring more inspiration to this hot topic of research.
有效捕获和储存核废料中的挥发性分子碘具有重要意义。共价有机框架（COFs）是一类具有独特结构的扩展结晶多孔聚合物，具有高比表面积、长程有序和永久孔隙率。人们已经投入大量精力来设计和合成 COF 材料，以捕获放射性碘。在本文中，我们首先介绍了确定 COF 材料捕获碘机制的研究技术。然后，对碘捕获性能的影响因素进行分类，并在此基础上总结了构建具有潜在碘捕获能力的 COFs 的设计原则和策略。最后，我们对存在的挑战和未来的发展趋势提出了个人的见解，以期为这一热门研究课题带来更多的启示。
