脂肪酸铕配合物聚合物材料的合成及发光性质

以一定比例正辛酸和月桂酸为第一配体，通过皂化法合成了脂肪酸铕配合物，并溶于甲基丙烯酸甲酯（MMA）单体通过本体聚合得到了含脂肪酸铕的PMMA光致发光聚合物材料AxByEu/PMMA（其中A=正辛酸根，B=月桂酸根，x、y分别表示正辛酸和月桂酸的比例）。考察了不同的第二配体（咔唑、二甲基-联吡啶、邻菲罗啉、噻吩甲酰三氟丙酮HTTA）对脂肪酸铕聚合物发光性能的影响，选择出合适的第二配体HTTA，进而合成了A3Eu/HTTA/PMMA聚合物。通过红外光谱、紫外光谱及荧光光谱对脂肪酸铕配合物及聚合物的结构和荧光性能进行表征。结果表明：合成的脂肪酸铕配合物及其聚合物均具有很好的光致发光性能，紫外激发能发射Eu3+离子的特征红光。当HTTA的质量分数减小至0.02%时，仍能很好地促进体系的发光，且不影响聚合物本身的透明性。

The study of (C8H15O2)x( C12H23O2)yEu/PMMA luminescent material

New kinds of rare earth europium complexes (C8H15O2)x(C12H23O2)yEu, which can directly solve in MMA monomer, were synthesized using the caprytlic acid (C8H15O2) and the lauric acid (C12H23O2) as the first ligand by Saponification Method. Photoluminescent PMMA containing rare earth complexes AxByEu/ PMMA (A= -C8H15O2，B= -C12H24O2, x、y was their mol ratio）were prepared by Bulk polymerization. The effect of different second ligand (carbazole, dmbp, phen, HTTA) on the flourescent properties of polymers were studied. Then AxByEu/HTTA/PMMA was prepared using the best second ligand HTTA. The structures and fluorescence properties of the complexes and polymers containing Europium were investigated by IR , UV and Fluorescence spectra spectrum. Results indicated that polymers we obtained emitted strong characteristic of Eu3+ ions. What`s more, even if the quality score of HTTA was 0.02%(wt%), could enhance the characteristic red luminescent of (C8H15O2)3Eu/HTTA/PMMA greatly. While the transparency of polymer wasn`t affected.
