摘　　要：合成一例结构稳定的锆基金属-有机框架材料(MOF-808),通过X射线粉末衍射(XRD)、全自动比表面及孔隙度分析仪、扫描电子显微镜(SEM)等表征手段对MOF-808的结构和形貌进行详细表征。在此基础之上,探究该材料在水溶液中对NO等小分子的荧光响应性能。研究结果表明:MOF-808对水溶液中NO分子具有独特的荧光响应性能,荧光猝灭效率高达55%。A kind of stable zirconium containing metal organic frameworks, named Zr-based metal organic frameworks(MOF-88), has been successfully prepared and characterized by X-ray diffraction(XRD), automated surface area and porosity analyzer, as well as scanning electron microscopy(SEM). In addition, the performance of MOF-808, fluorescence response to NO molecules, has also been studied here. According to experimental results, the fluorescence quenching efficiency of MOF-808 is up to 55% when MOF-808 nano particles dispersed in NO aqueous solution.
