后修饰MOF材料用于工业废气荧光检测的研究进展

Research progress on post-synthetic modification MOF materials for fluorescent determination of industrial exhaust gases

随着工业和农业高水平的发展,工业废气的过量排放,对全球气候和环境产生了重大影响。开发一种灵敏度高、操作简单的检测方法,对于环境监测具有重要意义。后修饰MOF材料兼具了MOF的孔隙率高、比表面积大、孔径可调、化学稳定性等优点和光致发光特性,同时在荧光传感方面展现出易于诱导发光、结构和功能成分多样以及检测机制多样等优点,因而在工业废气荧光检测领域表现出良好的应用前景。主要介绍了金属有机框架材料的改性策略及方法,评述近年来后修饰MOF材料对工业有毒气体和挥发性有机物的荧光传感的研究进展,并对后修饰MOF材料面临的问题与挑战和未来的发展方向进行了展望。

With the development of high-level industry and agriculture,excessive emission of industrial exhaust gases has had a significant impact on the global climate and environment.Developing a highly sensitive and operationally simple detection method is of great significance for environmental monitoring.Post-synthetic modification MOF materials have the advantages of high porosity,large specific surface area,tunable pore size,chemical stability,and luminescence properties,while exhibiting diverse advantages in terms of inducible fluorescence,structural and functional diversity and diverse detection mechanisms,thus making them ideal for fluorescence detection industrial exhaust gases.This paper mainly introduced the modification strategies and methods of metal-organic framework(MOF)materials,and then reviewed the research progress of post-synthetic modification MOF materials for fluorescence sensing of industrial toxic gases and volatile organic compounds in recent years,and prospected the problems,challenges and future development directions of post-synthetic modification MOF materials.
