金属有机框架材料在荧光传感方面的研究进展

The metal-organic frameworks(MOFs)have the characteristics of high porosity and crystallinity,which also makes MOFs have the advantages of high sensitivity,high selectivity and high efficiency in the field of fluorescence sensing.It can detect the target substance efficiently and quickly,and has excellent anti-interference.Therefore,MOFs materials are also considered as ideal materials for fluorescence sensors.This paper introduces three common preparation methods of MOFs materials:hydrothermal/solvothermal method,mechanochemical method and microwave method.We focus on the application status of MOFs materials in the three fluorescence sensing fields of small molecules,metal cations and inorganic anions,as well as the shortcomings and improvement methods of MOFs materials in this application field.Finally,in view of the shortcomings of MOFs materials in the field of fluorescence sensing,such as poor stability,fluorescence quenching phenomenon susceptible to environmental interference,etc.,it is proposed that more in-depth research should be carried out in the future in terms of anti-interference and reuse of MOFs materials.

金属有机框架(MOFs)材料因具有高孔隙率和高结晶度等特点,使得MOFs材料在荧光传感领域具有高灵敏性、高选择性和高效性的优点。本综述主要介绍了MOFs材料的几种常用制备方法,简述3种不同类型的MOFs材料的荧光传感,重点论述MOFs材料在小分子、金属阳离子和无机阴离子3个荧光传感领域的应用现状。最后针对MOFs材料在荧光传感领域存在稳定性较差、荧光淬灭现象易受环境干扰等不足,提出应该在MOFs材料的抗干扰性、重复利用性等方面开展更加深入的研究。
