摘要: 在溶剂热条件下合成了一种新型金属有机框架(MOF){[Zn2(tyia)2(H2O)2]·H2O}n(1),其中H2tyia为5-(1H-1,2,4-三唑-1-基)间苯二甲酸。运用X射线单晶衍射分析其结构,通过元素分析、粉末X射线衍射、热重分析、固体荧光分析等手段对配合物1进行表征,研究了其与有机小分子相互作用的荧光特性。结果表明其能够对低浓度苯乙烯迅速做出反应,最低识别浓度为1.06 mmol·L-1。此外,还对其传感机制进行了研究。 |

Abstract: A new three-dimensional Zn2+-based metal-organic framework (MOF), {[Zn2(tyia)2(H2O)2] ·H2O}n (1), where H 2tyia is 5-(1H-1,2,4-triazol-1-yl) isophthalic acid, was synthesized under solvothermal conditions. The structure of compound 1 was analyzed by X-ray single crystal diffraction, and characterized by elemental analysis, powder X-ray diffraction, thermogravimetric analysis and solid fluorescence analysis. The fluorescence characteristics of the interaction between compound 1 and small organic molecules were studied. The results show that 1 can response quickly to low concentration of styrene, and the minimum identification concentration is 1.06 mmol·L-1. Furthermore, a possible sensing mechanism was investigated. |
