摘    要:在溶剂热条件下合成了3个新型三维微孔同构异核金属有机骨架Ln (Na)-MOFs:{[LnNa (BDT)(H2O)3]·2H2O}n(Ln=Tb (1)、Dy (2)、Ho (3),H4BDT=3,5-二(3'',5''-二羧基苯基)-1H-1,2,4-三唑),并通过单晶X射线衍射、元素分析、热重分析和粉末X射线衍射技术对其进行表征。结构分析表明,Ln (Na)-MOFs是具有相同的异核双金属单元的三维骨架结构。荧光研究表明,Tb (Na)-MOF (1)可以荧光传感检测水中Fe3+、Cr2O72-以及乙醛分子,具有较高的灵敏度和选择性,也可用于水中邻苯二酚的电化学检测。

关 键 词:异核金属有机骨架  晶体结构  荧光传感  电化学传感

Abstract:Three new 3D microporous isostructural heterometallic metal organic frameworks Ln(Na)-MOFs:{[LnNa(BDT)(H2O)3]·2H2O}n (Ln=Tb (1), Dy (2), Ho (3), H4BDT=3,5-bis(3'',5''-dicarboxylphenyl)-1H-1,2,4-triazole), have been synthesized under solvothermal condition, and characterized by single crystal X-ray diffraction, elemental analysis, thermogravimetric analysis, and powder X-ray diffraction. Structural analysis demonstrates that they possess the same 3D frameworks based on similar heteronuclear bimetallic units. Fluorescence studies show that Tb (Na)-MOF (1) can detect Fe3+ ion, Cr2O72- anion, and acetaldehyde molecules with high sensitivity and selectivity by luminescent sensing, and can also be used for electrochemical detection of catechol in water.
Keywords:heterometallic metal organic frameworks  crystal structure  luminescent sensing  electrochemical sensing
