金属有机框架（MOFs）作为荧光传感材料是近年来的研究热点。本项目拟利用镧系离子良好的光学性能，构筑镧系金属有机框架（LMOFs）荧光传感材料。拟采用“Click”反应的后合成修饰策略，将目标官能团引入到LMOFs的有机骨架上，实现LMOFs的功能化修饰；研究修饰后LMOFs的荧光传感性能与其结构的关系，阐明其可能的荧光传感机理，为制备具有专一识别性能的LMOFs荧光传感材料提供理论依据。

Recently, it become a research focus for metal-organic frameworks (MOFs ) as fluorescent sensors. In this project, lanthanide metal-organic frameworks (LMOFs) will be synthesized as fluorescent sensors by taking advantage of the excellent optical properties of lanthanide ions. Besides, one of the post-synthetic modification (PSM) strategy, i. e. click reaction, will be used to introduce the target chemical groups into the linkers of LMOFs, realizing the functionalization of LMOFs. The relationship between the modified LMOFs’ structures and their fluorescent sensor properties will be investigated, and their fluorescent sensor mechanism will be proposed. LMOFs with special fluorescent sensor properties will be prepared based on these studies.
