| 摘 要： | 以四水合硝酸镉(Cd(NO_3)_2·4H_2O)与2-(邻溴)苯基-4,5-咪唑二羧酸(o-BrPhH_3IDC)和草酸铵通过水热反应,合成了一个波浪形一维链状配合物{Cd(o-BrPhH_2IDC)_2(H_2O)]·H_2O}_n(1)。并通过元素分析、傅里叶变换红外光谱、热重分析和单晶X射线衍射等技术手段对配合物1进行了表征。结果表明,配合物1为正交晶系,Pbca空间群。配合物1在316 nm波长激发下,在356 nm处有最大的荧光发射峰。配合物1对小分子具有识别性能,乙腈使配合物荧光强度明显增强,甲醇、乙醇使配合物荧光强度明显减弱,而吡啶处理后的样品在356 nm附近的发射峰消失,显示对吡啶有识别作用。

| Abstract: | By the hydrothermal reaction of Cd(NO3)2·4H2O with 2-(2-bromophenyl)-1H-imidazole-4,5-dicarboxylic acid(o-BrPhH3IDC) and ammonium oxalate, a new wave-shaped chain complex {Cd(o-BrPhH2IDC)2(H2O)]·H2O}n(1) was synthesized and characterized through elemental analysis, Fourier transform infrared spectrometer, thermogravimetric and single crystal X-ray diffraction analysis. The results show that complex 1 crystallizes in the orthorhombic space group Pbca. Excited by the wavelength of 316 nm, complex 1 shows the maximum fluorescence emission peak around 356 nm. Further experiments show that acetonitrile significantly increases the fluorescence intensity of complex 1, and methanol and ethanol may decrease the fluorescence intensity. If complex 1 is treated with pyridine, the fluorescence emission peak of complex 1 disappears, which indicates selective recognition for pyridine. |
