以丙烯酸(HAA)、甲基丙烯酸(HMA)及1,10-邻菲罗啉(Phen)为配体与氧化铕(Eu2O3)反应得到二元配合物Eu(AA)3、Eu(MA)3和三元配合物Eu(AA)3Phen、Eu(MA)3Phen。将生成的配合物与HMA和甲基丙烯酸甲酯(MMA)共聚,得到一系列三元共聚物。通过元素分析、红外光谱、荧光光谱和热分析对配合物进行了分析与表征,发现配合物具有良好的荧光强度和热稳定性。三元配合物的荧光强度相对于二元配合物有显著提高。共聚物可发射Eu3+的特征荧光,荧光强度随配合物含量的增加而增加,且未发生浓度猝灭现象。三元配合物在反应单体MMA和HMA中的溶解度低于二元配合物,从而使在最大溶解度下二元配合物与反应单体生成共聚物的荧光强度高于相应的三元配合物与反应单体生成的共聚物。
The binary complexes Eu (AA) 3 and Eu (MA) 3 were obtained by the reaction of europium oxide (Eu2O3) with acrylic acid (HAA), methacrylic acid (HMA) and phenanthrene And ternary Eu (AA) 3Phen, Eu (MA) 3Phen. The resulting complex was copolymerized with HMA and methyl methacrylate (MMA) to give a series of terpolymers. The complexes were analyzed and characterized by elemental analysis, infrared spectroscopy, fluorescence spectroscopy and thermal analysis. The results showed that the complexes have good fluorescence intensity and thermal stability. The fluorescence intensity of the ternary complex is significantly higher than that of the binary complex. The copolymer can emit the characteristic fluorescence of Eu3 +, the fluorescence intensity increases with the increase of the content of the complex, and no quenching of the concentration occurs. The solubility of the ternary complex in the reaction monomers MMA and HMA is lower than that of the binary complex so that the fluorescence intensity of the copolymer of the binary complex and the reactive monomer at the maximum solubility is higher than that of the corresponding ternary complex and Copolymers of reactive monomers.
