发光共价有机框架材料在污染物检测中的应用研究进展

Abstract： Environmental pollutants， such as heavy metal ions and organic contaminants， have emerged as a se• vere global challenge.How to effectively detect environmental pollutants has become a scientific problem ， which has garnered extensive attention from a growing number of scientists and engineers.Conventional detection methods are often hampered by high costs， poor portability， and operational complexity.Therefore， we need to design and devel• op rapid， simple， highly selective and sensitive detection techniques for pollutant monitoring.Luminescent covalent organic frameworks (LCOFs)， a class of porous luminescent materials interconnected by covalent bonds， possess highly ordered crystal structures， excellent stability， and tunability， demonstrating significant potential in the field of pollutant detection.This review begins by outlining the types， synthetic strategies， and procedure methods of LCOFs.Furthermore， various applications in pollutant detection have been explored， with a detailed discussion on their use in identifying heavy metal ions， antibiotics， persistent organic pollutants， endocrine disruptors， nitro-explo• sives， and other environmental contaminants.Finally， the review highlights the critical role of LCOFs in environmen• tal monitoring and offers perspectives on future development trends.Keywords： luminescent materials； covalent organic frameworks； pollutant detection； research progress 文章编号： 1000
