【摘要】 合成了铕与长链羧酸、二苯甲酰甲烷、邻菲啰啉形成的四元配合物,用元素分析、红外光谱、核磁共振氢谱和紫外光谱对所合成的铕四元配合物进行了表征。由于长链羧酸的引入,铕配合物在氯仿等挥发性有机溶剂中具有良好的溶解性,这为今后与高分子基体复合创造了条件。铕配合物在342nm光波激发下,发出以铕的特征发射谱线612nm左右为主的强荧光。更多还原

【Abstract】 Europium quaternary complex was synthesized with dibenzoylmethane,1,10-phenanthroline,a long carbon chain carboxylic acid and characterized by EA,FT-IR, 1HNMR and UV.The Eu(Ⅲ) complex is easily soluble in volatile organic solvents such as chloroform due to the introduction of long carbon chain carboxylic acid,which is in favor to the composite formation with polymer materials.The Eu(Ⅲ) complex spectra were excited with a wavelength of 342nm,exhibited a red color with characteristic peaks at 592,612nm.The 612nm transition shows the strongest emission.更多还原
