摘　　要：在溶剂热条件下,以4,4’-磺酰基二苯甲酸(H_(2)SDBA)为配体与硝酸铕构建出具有荧光性质的稀土有机框架[Eu_(2)(SDBA)_(3)(H_(2)O)_(4)]·NMP(NMP=N-甲基吡咯烷酮),并对其进行粉末X射线衍射、荧光光谱、紫外吸收光谱等手段表征.X射线单晶衍射分析结果显示该材料具有三维结构.Eu-MOFs具有良好的荧光性能,能够在水中同时实现对维生素B4和阿奇霉素的高灵敏及高选择的荧光淬灭检测.A new metal-organic framework(MOF),[Eu_(2)(SDBA)_(3)(H_(2)O)_(4)]·NMP(H_(2)SDBA=4,4’-sulfonyldibenzoic acid;NMP=N-methylpyrrolidone),has been successfully synthesized under solvothermal condition.The complex is characterized by PXRD,PL and UV-Vis.The X-ray single crystal diffraction analysis reveals that the compound has a three-dimensional structure.It has some desired fluorescence properties and can achieve highly sensitive and highly selective fluorescence quenching detection with vitamin B4 and azithromycin in aqueous.
