摘　　要：以1,3,5-三(咪唑基)苯(tib),4,4-二苯醚二甲酸(H2L)和Cd(NO3)2·6H2O为原料,在水热条件下合成了一个新的Cd(Ⅱ)配合物[Cd2(L)4(tib)2DMF]n·DMF(Cd-2 MOF)(1,CCDC:1901161),其结构经IR,元素分析和X-射线单晶衍射表征。结果表明:配合物1属三斜晶系,P 21/n空间群,晶胞参数a=10.0363(9)A,b=14.1842(13)A,c=20.2842(18)A,α=97.754(3)°,β=98.410(3)°,γ=104.960(3)°。室温固态荧光测试结果显示配合物1具有很强的发射峰,并研究其变温荧光性质,通过后功能化修饰掺杂稀土元素实现了Ln^3+封装的MOF(Ln=Eu,Tb,Eu/Tb)材料发射的细调。A new Cd(Ⅱ)complex was synthesized under hydrothermal conditions using 1,3,5-tris(imidazolyl)benzene(tib),4,4-diphenyl ether dicarboxylic acid(H2L)and Cd(NO3)2·6 H2O as raw materials.[Cd2(L)4(tib)2DMF]n·DMF(Cd-2 MOF)(1,CCDC:1901161).The structure was characterized by IR,elemental analysis and X-ray single crystal diffraction.The results showed that compound 1 belongs to triclinic system,space group P 21/n with a=10.0363(9)A,b=14.1842(13)A,c=20.2842(18)A,α=97.754(3)°,β=98.410(3)°,γ=104.960(3)°.Compound 1 has a strong emission peak in the solid state at room temperature.Meanwhile,The temperature-variable fluorescence has been explored to some extent.By post-functionalization of doped rare earth elements,the fine emission of Ln^3+-encapsulated MOF(Ln=Eu,Tb,Eu/Tb)material is achieved in the titration experiment tune.
