摘　　要：合成含咔唑基团、含1,3,4-噁二唑基团、含稀土铕配合物的3类可聚合的单体,其结构用红外光谱、质谱、元素分析、核磁共振表征.通过自由基共聚方法制备了多功能合一的含铕共聚物,用元素分析、凝胶液相色谱、TGA、DSC和紫外光谱确认结构并表征性质;用荧光光谱研究它们的光致发光性质,讨论了不同状态、不同噁二唑基团取代基对发光机理的影响.Individual monomers containing the europium complex, 1,3,4-oxadiazole group and carbazole group were synthesized. Their structures were confirmed by FT-IR, EI-MS, Element analysis,Ill NMR. The muti-functional copolymers containing europium were prepared through radical copolymerization of these monomers. Their structure were characterized by Element analysis, GPC,TGA,DSC, UV absorption. On the baris of the characterization of the photoluminescence properties of the copolymers with fluorescence spectra, the effect of excited states and substituted oxadiazole groups of the copolymers on PL mechanism was investigated.
