摘　　要：以三(4-(1 H-咪唑-1-基)-苯基)胺(Tipa),富马酸(H^(2)fuma)和Cd(NO_(3))_(2)·6H_(2)O为原料,溶剂热法在100℃下合成了一种新的Cd(Ⅱ)配合物[Cd(fuma)(Tipa)_(3)Cl]_(n)(CP1),其结构经X-射线单晶衍射,IR,元素分析表征。CP1属单斜晶系,C 2/c空间群,晶胞参数a=21.5503(10)A,b=14.9847(6)A,c=18.2554(10)A,α=90°,β=99.687(5)°,γ=90°。固体荧光激发依赖测试结果显示配合物CP1对激发光具有依赖性,并研究了其变温荧光,液体荧光的测试结果显示,CP1可以作为检测Fe^(3+)和Mn^(2+)离子的双响应荧光化学传感器。A novel Cd(Ⅱ)coordination polymer,[Cd(fuma)(Tipa)3 Cl]n(CP1),was synthesized by solvothermal method at 100℃.Tris(4-(1 H-imidazol-1-yl)-phenyl)amine(Tipa),fumaric acid(H 2 fuma)and Cd(NO_(3))_(2)·6H_(2)O were used as raw materials.The structure and thermal property were characterized by X-ray single crystal diffraction,IR and elemental analysis.The results showed that CP1 belongs to monoclinic system,space group C 2/c with a=21.5503(10)A,b=14.9847(6)A,c=18.2554(10),α=90°,β=99.687(5)°,γ=90°.The results of solid fluorescence excitation dependence test showed that the complex CP1 had dependence on the excitation light,and its temperature-varying fluorescence has been studied.The liquid fluorescence test results showed that CP1 could be used as a dual-response fluorescence chemical sensor for detecting Fe^(3+)and Mn^(2+).
