| 摘 要： | 稀土元素由于特殊的外层电子构型,在与不同类型配体配位时,呈现出丰富多彩的配位行为和结构,其配合物,特别是有机配合物,由于具有发光性强、选择性好的特点,在发光、激光材料创制、结构探针、荧光免疫分析及生物传感器等领域的研究和应用引起广泛关注.氨基酸、肽是各种生物大分子的基本组成单元,咪唑存在于组氨酸、羧肽酶、血红蛋白等生物分子中参与配位或"变构效应"成为活性部位结构,唑环有丰富的能级,其作为含N富电子体系可与稀土离子形成既有生物活性,又有优良光学性能的配合物. |

| Abstract: | Two new coordination compounds of rare earth chloride with N-acetyl-DL-alanine and imidazole have been prepared from absolute alcohol. The general formula RE(C5H8NO3)2(C3H5N2)2Cl3·4H2O (RE=Ce, Pr) of these compounds were identified, by chemical and elemental analysis, FTIR spectra, UV spectra, 1H NMR and 13C NMR spectra, and molar conductance. The processes of thermal decomposition were identified by TG-DSC curves. The possible reaction mechanisms and the kinetics equation were investigated by comparing the kinetics parameters. The activation entropy of dehydration, as well as enthalpy values of dehydration and decomposition were obtained by DSC curve. The three-dimensional fluorescence spectra of liquid compounds were measured. The phenomenon of the up-conversion fluorescence is discussed. |
| Keywords: | rare earth compound N-acetyl-DL-alanine imidazole spectral property |
