摘　　要：用D-氨基葡萄糖盐酸盐分别与硝酸铕和硝酸铽反应,制备了氨基葡萄糖-铕、氨基葡萄糖-铽两种配合物,并研究了配合物的红外光谱、紫外光谱和X射线光电子能谱(XPS)。配合物紫外的λmax发生了明显紫移,在远IR区Glu-Eu配合物中出现的新的吸收峰206 cm-1和254 cm-1可分别归属于νEu-O和νEu-N,在Glu-Tb配合物中出现的新的吸收峰203 cm-1和252 cm-1可分别归属于νTb-O和νTb-N,XPS表明氨基葡萄糖-Ln中氨基葡萄糖的N和O原子上的电子云密度减少,孤对电子转移,稀土离子得到电子。The Glu-Eu and Glu-Tb coordination compounds were synthesized from D-glucosamine hydrochloride with Eu（NO_3）_3 and Tb（NO_3）_3,respectively.IR,UV and X-ray photoelectron spectroscopy of the compexes were studied.In UV spectra,the λ_（max） of the complexes showed obvious violet shift when compared with that of the glucosamine.In far infrared spectra of the complexes,two new bands 206 cm～（-1） and 254 cm～（-1） appeared for Glu-Eu compound which were attributed to ν_（Eu-O） and ν_（Eu-N）,while another two new bands 203 cm～（-1） and 252 cm～（-1） appeared in Glu-Tb compound attributed to ν_（Tb-O） and ν_（Tb-N）.XPS results indicated that the electron pair of the N atom and O atom of glucosamine shifted to the rare earth ion.
