将具有聚合活性的稀土铕有机配合物Eu3+(BA)2(AA)(phen)与苯乙烯共聚得到一种半透明且发光强度高的稀土高分子光致发光材料,通过凝胶色谱、红外光谱、紫外光谱对其结构进行表征,证实是共聚物,而不是共混掺杂.通过荧光光谱分析说明只要引入少量的稀土配合物单体,共聚物就表现出配合物单体的强紫外吸收特性,并发射出Eu3+的特征荧光.热分析则表明共聚物引入稀土配合物基团后,其热稳定性得到了提高,而稀土配合物键合到大分子链后其结构单元热稳定性也得到相应的提高.

Copolymers containing rare earth complex were prepared via copolymerizing complex Eu3+(BA)2(AA)(phen)) with styrene. A sort of semitransparent luminescent polymer material with high fluorescent intensity was obtained. They were characterized by means of IR and UV spectra, which show that they were copolymers, not blendings. The fluorescence spectra of copolymer indicated that it showed intense UV absorption characteristics of rare earth complex as long as only a little complex join in it. Moreover, thermal analysis showed that they had excellent heat-stability.
