对十二烷氧基苯甲酸铕四元配合物的合成及其光致发光

Synthesis and Photoluminescence of Europium Quaternary Complex with Dodecyloxy Benzoic Acid-dibenzoylmethane-1,10-phenanthroline

合成了对十二烷氧基苯甲酸-二苯甲酰甲烷(DBM)-邻菲罗啉(phen)-铕四元配合物,用元素分析(EA)、红外光谱(FT-IR)、氢谱(1HNMR)和紫外光谱(UV)对所合成的铕配合物进行了表征;由于长链的引入,配合物在氯仿等挥发性有机溶剂中具有好的溶解性,为以后与高分子基体复合创造了条件;配合物在波长342 nm激发下,发出以铕的特征发谢谱线615 nm左右为主的强荧光.

Europium quaternary complex was synthesized with dodecyloxy benzoic acid- dibenzoylmethane-1,10- phenanthroline and characterized by EA,FT-IR, HNMR and UV. Eu（Ⅲ） complex is easy soluble in volatility organic solvents such as chloroform because of introducing long carbon chain cardoxylic acid, which benefits to composite with polymer materials. The Eu（Ⅲ） complex spectra were excitated by a wavelength with 342 nm ,it exhibited a red emissive color and the Eu characteristic peaks are at 592,615 nm,615 nm transition shows the strongest emission.
