The discharge of excessive metal ions and anions into water bodies leads to the serious pollution of water and environment, which in turn has a certain impact on industry, agriculture, and human life. Because of the unique advantages of luminescent metal-organic frameworks (LMOFs), they have been successfully explored as various fluorescent probes to quickly and effectively detect these pollutants. This perspective not only introduces the design strategy and classification of LMOFs, especially the construction methods of water-stable LMOFs, but also reports the latest progresses in some LMOFs between 2016 and 2020 as well as expounds the mechanisms of LMOFs for detecting anions and cations. Moreover, the luminescence properties of LMOFs are related to the selection of metal ions, the structure of organic ligands, the pore size, and the interaction of guest molecules. Finally, the further development of LMOFs is summarized and prospected in this field.
将过多的金属离子和阴离子排放到水体中会导致水和环境的严重污染，这反过来又会对工业、农业和人类生活产生一定的影响。由于发光金属-有机骨架（LMOFs）的独特优势，它们已被成功探索作为各种荧光探针，以快速有效地检测这些污染物。本观点不仅介绍了 LMOFs 的设计策略和分类，特别是水稳定 LMOFs 的构建方法，还报告了 2016 年至 2020 年期间 LMOFs 的最新进展，并阐述了 LMOFs 检测阴离子和阳离子的机制。此外，LMOFs 的发光性质与金属离子的选择、有机配体的结构、孔径以及客体分子的相互作用有关。最后，对该领域 LMOFs 的进一步发展进行了总结和展望。
