【摘要】 成功制备了新型Zn（Ⅱ）金属有机骨架（MOF）[Zn₂（Hdepa）（dya）₂]_n（1）（H₅depa=2,2’,3,4’,5-二苯醚五羧酸,dya=2,2’-二吡啶胺）。单晶X射线衍射分析表明MOF 1由2个Zn²⁺离子与1个Hdepa^4-离子和2个dya分子连接组成,通过氢键形成三维骨架。用粉末X射线衍射和IR表征了配合物1的相纯度。值得注意的是,配合物1具有优异的荧光特性和热稳定性,1的高灵敏度和选择性使其能够作为荧光传感器检测苯甲醛（BZH）、四环素（TC）、2,4,6-三硝基苯酚（TNP）、氟啶胺（Flu）、Cr₂0₇^2-和Fe³⁺。此外,通过荧光寿命分析了Fe³⁺、TC、BZH对MOF 1的荧光的猝灭过程,通过能量转移研究了Fe³⁺、Cr₂O₇^2-、TNP、TC、BZH和Flu的荧光猝灭机理。更多还原

【Abstract】 A novel Zn（Ⅱ） metal-organic framework（MOF） [Zn₂（Hdepa）（dya）₂]_n（1）（H₅depa=2,2’,3,4’,5-diphenyl ether pentacarboxylic,dya=2,2’-dipyridyl amine） was successfully prepared.Single-crystal X-ray diffraction analysis indicates that MOF 1 is composed of two Zn²⁺ ions joining one Hdepa^4-ion and two dya molecules,forming a 3D framework through hydrogen bonding.The phase purity of the MOF 1 was demonstrated by powder X-ray diffraction and IR.Interestingly,1 has excellent fluorescence properties and thermal stability.Notably,due to its excellent fluorescence performance,the high sensitivity and selectivity of 1 enable it to be used as a fluorescence sensor to detect C₆H₅CHO（BZH）,tetracycline（TC）,2,4,6-trinitrophenol（TNP）,fluazinam（Flu）,Cr₂O₇^2-,and Fe³⁺.In addition,the quenching process of Fe³⁺,TC,and BZH to MOF 1 was analyzed by fluorescence lifetime,and the fluorescence quenching mechanism of Fe³⁺,Cr₂O₇^2-,TNP,TC,BZH,and Flu was studied by energy transfer.CCDC:2172003.更多还原
