以丙烯酸(AA)为第一配体、邻菲罗啉(Phen)为第二配体、Eu3+为中心离子,合成了一种可聚合的稀土铕配合物.以配合物单体、甲基丙烯酸甲酯、丙烯酰胺和对苯乙烯磺酸钠为共聚单体,通过无皂乳液聚合的方法,制备了含铕荧光共聚物乳液.采用红外光谱对共聚物的结构进行了表征,并探讨了配合物单体含量对共聚物乳液性能的影响.透射电子显微镜(TEM)和激光光散射粒度仪(PCS)测试结果表明,共聚物乳液形成了相对均一的球状结构,但随着配合物单体含量增加,共聚物微球粒径逐渐增大、分散性变差.采用荧光分光光度计测试了共聚物乳液的荧光性能,在594和619 nm处出现Eu3+的特征发射光谱,且荧光强度随着配合物单体含量增加而增强.
A new kind of rare earth europium complex was synthesized by using acrylic acid (AA) as the first ligand, phenanthrene (Phen) as the second ligand and Eu3 + as the central ion. The complex monomer, methacrylic acid Methyl acrylate, acrylamide and sodium p-styrene sulfonate as comonomers were synthesized by emulsion-free emulsion polymerization of europium-containing fluorescent copolymer emulsion structure was characterized using infrared spectroscopy and discussed the coordination The influence of monomer content on the properties of copolymer emulsion.The results of transmission electron microscopy (TEM) and laser light scattering particle sizer (PCS) showed that the copolymer emulsion formed a relatively uniform spherical structure, but with the monomer content , The particle size of the copolymer microspheres gradually increased and the dispersibility deteriorated.The fluorescent properties of the copolymer emulsion were tested by fluorescence spectrophotometer.The characteristic emission spectra of Eu3 + appeared at 594 and 619 nm, Monomer content increased and increased.
