摘　　要：在蒸馏水介质中通过La(ClO4)3.nH2O与L-谷氨酸以及咪唑合成了一个新三元配合物[La(C5H9NO4)3-(C3H4N2)(]ClO4)3.3H2O。通过元素分析、摩尔电导、红外光谱、紫外光谱对配合物进行了表征,确定了其组成。通过TG-DTG测定进一步研究了配合物的配位行为及热稳定性。测定了配合物水溶液的荧光光谱,并与配体的荧光光谱相比较,讨论了配合物的发光机制。A new coordination compound [La（C5H9NO4）3-（C3H4N2）]（ClO4）3·3H2O was synthesized in aqueous solution by lanthanum perchlorate with glutamic and imidazole.The general formula of the resulting compound was identified by elemental analysis,molar conductivity,FT-IR spectra,and UV-vis spectra.The process of thermal decomposition was identified by TG curves.The fluorescence properties of the lanthanum complex were investigated.In addition,a possible intermolecular energy transfer mechanism was discussed.
