摘　　要：以2-氰基吡啶和盐酸羟胺为起始原料反应得到偕胺肟;与丁二酸酐在熔融条件下反应,得到3-(3-(吡啶-2-基)-1,2,4-噁二唑-5-基)丙酸配体;最后丙酸配体与Yb(NO_(3))3生成稀土配合物1,丙酸配体与ZnCl 2及Yb(NO_(3))3生成稀土配合物2。新生成的配合物进行红外、紫外、热失重表征,荧光光谱对其发光的应用性能研究。Amidoxime was synthesized from 2-cyanopyridine and hydroxylamine hydrochloride;Ligand of 3-(3-(pyridine-2-yl)-1,2,4-oxadiazole-5-yl)propionic acid was obtained by reaction with succinic anhydride under melting condition;Finally,propionic acid ligand reacts with Yb(NO_(3))3 to form rare earth complex 1,and propionic acid ligand reacts with ZnCl 2 and Yb(NO_(3))3 to form rare earth complex 2.The new complexes were characterized by IR,UV and TG,and their luminescent properties were studied by fluorescence spectra.
