铕配合物与苯乙烯共聚物的研究 潘远凤1,胡福增1,郑安呐1,蔡平雄1 (1.华东理工大学,超细材料制备与应用教育部重点实验室,上海,200237) 摘要: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. 关键词:铕配合物; 含稀土聚合物; 荧光性; europium complexes; rare earth metal-containing polymer......
