摘要:一个三维多孔层金属有机框架溶剂热条件下合成。该结构通过单晶X-射线衍射分析,粉末X射线衍射分析,热重分析,红外光谱分析和元素分析进行了表征。 标题化合物呈现了具有(3,4)-连接拓扑的三维多孔层状结构,具有较高的结构稳定性,同时可应用于小分子传感,例如硝基苯和2,4,6-三硝基苯酚。此外,该化合物可以作为基于金属有机框架的荧光探针靶向环境相关的客体物种,如检测在水溶液中的二价汞离子,是具有高的选择性和灵敏度。

A fluorescent sensor for highly selective sensing of nitro explosives and Hg (II) ion based on a 3D porous layer metal-organic framework
Abstract:A 3D porous layer metal-organic framework was synthesized under a solvothermal condition. The structure was characterized by single crystal X-ray diffraction analysis, powder X-ray diffraction (PXRD) analyses, thermogravimetric analysis (TGA), infrared spectrometry analysis and elemental analysis. The structure of 1 displays a 3D porous layer and can be classified as a (3,4)-connected topology. The framework is stable to a certain degree. 1 can also be applied as a fluorescent sensor for small-molecule sensing, such as nitrobenzene (NB) and 2,4,6-trinitrophenol (TNP). In addition, 1 is the rare example of MOF-based fluorescent probes targeting environmentally relevant guest species, such as Hg (II) ion in aqueous solution, with high selectivity and sensitivity.
