摘要
利用不饱和二元羧酸3-己烯二酸(H2L)、1,10-邻菲咯啉(Phen)与稀土铕的氯化物EuCl3反应,合成了具有发光性能的稀土铕三元配合物Eu2L3Phen.4H2O。将铕配合物与聚甲基丙烯酸甲酯(PMMA)掺杂后,研究了掺杂型高分子材料的光致发光性能。研究结果表明,Eu配合物能发出很强的铕离子特征荧光,当配合物Eu2L3Phen.4H2O与聚甲基丙烯酸甲酯掺杂后,高分子材料仍能发出配合物Eu2L3Phen.4H2O的特征荧光,高分子材料的发光强度随着配合物在聚甲基丙烯酸甲酯中掺杂量的增加而增加。
Europium ternary complex Eu2L3Phen·4H2O with luminescent properties was synthesized by the reaction of the unsaturated dicarboxylic acid 3-hexene acid （H2L） with 1,10-phenanthroline （Phen） and the EuCl3. The photoluminescence properties of the doping polymer materials were researched after the europium complex was doped to polymethyl methacrylate （PMMA）. The results show that Eu complexes can send strong fluorescence characteristics of the europium ion. After the complex Eu2L3Phen·4H2O was doped to PMMA, polymer materials also send fluorescence characteristic of complex Eu2L3Phen·4H2O. The luminescence intensity of polymer materials increase with increasing content of complexes in PMMA.
