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。

Eu3 + (BA) 2 (AA) (phen), a rare earth europium complex with polymerization activity, was copolymerized with styrene to obtain a translucent and high luminescence intensity rare earth polymer photoluminescence material, which was characterized by gel chromatography, , Its structure was characterized by UV spectroscopy, proved to be a copolymer, rather than blend doping. Fluorescence spectrum analysis shows that as long as a small amount of rare earth complex monomer is introduced, the copolymer shows the strong ultraviolet absorption characteristic of the monomer of the complex and emits the characteristic fluorescence of Eu3 +. The thermal analysis shows that the thermal stability of the copolymer is improved when it is introduced into the rare earth complex, and the thermal stability of the structural unit is also improved when the rare earth complex is bonded to the macromolecular chain.
