摘　　要：在溶剂热的条件下,以1,3-双(咪唑)丙烷与均苯三酸作为混合配体,合成了一例锌(Ⅱ)的有机框架材料。即{[Zn_(2)(μ2-OH)L_(1)L_(2)]·DMAc·_(2)H_(2)O}n其中L_(1)为1,3-双(咪唑)丙烷,L2为1,3,5-苯三羧酸用表示,DMAc为N,N-二甲基乙酰胺。经X射线单晶衍射仪、红外光谱仪、粉末XRD、热重分析仪和元素分析仪表征,该MOF为3D→3D二重穿插三维骨架结构。此外,室温下固体荧光的测试结果表明:该MOF对苯胺有明显猝灭作用,所以MOF可以用在荧光分光光度计检测苯胺的传感器方面的应用。Under solvothermal conditions,an organic framework material of zinc(Ⅱ)was synthesized with 1,3-bis(imidazole)propane and trimellitic acid as mixed ligands.That is,{[Zn_(2)(2-OH)L_(1)L_(2)]DMAc·2H_(2)O}n,where L,is 1,3-bis(imidazole)propane,L,is 1,3,5-benzenetricarboxylic acid,and dmac is N,N-dimethylacetamide.The MOF was characterized by X-ray single crystal diffractometer,infrared spectrometer,powder XRD,thermogravimetric analyzer and elemental analyzer.The MOF has a 3D3D double-interspersed 3D skeleton structure.In addition,the test results of solid-state fluorescence at room temperature show that the MOF has obvious quenching effect on aniline,so MOF can be used as a sensor for detecting aniline by fluorescence spectrophotometer.
