Population growth and industrial development have exacerbated environmental pollution of both land and aquatic environments with toxic and harmful materials. Luminescence-based chemical sensors crafted for specific hazardous substances operate on host-guest interactions, leading to the detection of target molecules down to the nanomolar range. Particularly, the luminescence-based sensors constructed on the basis of metal-organic frameworks (MOFs) are of increasing interest, as they can not only compensate for the shortcomings of traditional detection techniques, but also can provide more sensitive detection for analytes. Recent years have seen MOFs-based fluorescent sensors show outstanding advantages in the field of hazardous substance identification and detection. Here, we critically discuss the application of MOFs for the detection of a broad scope of hazardous substances, including hazardous gases, heavy metal ions, radioactive ions, antibiotics, pesticides, nitro-explosives, and some harmful solvents as well as luminous and sensing mechanisms of MOF-based fluorescent sensors. The outlook and several crucial issues of this area are also discussed, with the expectation that it may help arouse widespread attention on exploring fluorescent MOFs (LMOFs) in potential sensing applications.
人口增长和工业发展加剧了土地和水生环境的环境污染，其中含有有毒有害物质。基于发光的化学传感器专门针对特定的有害物质进行设计，基于主体-客体相互作用进行操作，从而可以检测到纳摩尔级别的目标分子。特别是，基于金属-有机框架（MOF）构建的发光传感器越来越受到关注，因为它们不仅可以弥补传统检测技术的缺点，而且可以为分析物提供更灵敏的检测。近年来，基于 MOF 的荧光传感器在危险物质识别和检测领域表现出了突出的优势。在这里，我们批判性地讨论了 MOF 在检测广泛范围的有害物质中的应用，包括危险气体、重金属离子、放射性离子、抗生素、农药、硝基炸药以及一些有害溶剂，以及基于 MOF 的荧光传感器的发光和传感机制。还讨论了该领域的展望和几个关键问题，期望这可能有助于引起人们对探索潜在传感应用中的荧光 MOF（LMOF）的广泛关注。
