摘要
以对溴苯胺和对溴苯甲酸乙酯为原料,通过重氮化、乌耳曼、Suzuki偶联等一系列反应,合成了一种新型化合物4-((4′-N,N-二苯基)苯基)-苯甲酸(DNPPBA),进而以DNPPBA作第一配体和邻菲啉为第二配体,与Eu(ClO4)3反应,合成了一种三元配合物Eu(DNPPBA)3Phen。对其进行了表征及性质测定。荧光光谱结果显示既有蓝光发射,又有锐利的红光发射,复合起来接近白光,这为合成一种"单分子白光"材料提供了可行途径。
A novel compound 4-（（4＇-N, N-diphenyl） phenyl）- benzoic acid was synthesized from 4-bromoaniline and ethyl pbromobenzoate through a series of the Ullman and Suzuki coupling reactions. Using this synthesized ligand as the first ligand and 1,10-phenanthroline （Phen） as the second ligand, an europium （Ⅲ） ternary complex, Eu（DNPPBA）3Phen, was synthesized.The composition of the new ligand was comfirmed by elemental analysis and 1 HNMR spectroscopy. The properties of the Eu （ Ⅲ ） ternary complex were characterized by elemental analysis, IR and UV-Visible spectroscopy. The PL spectrum composes both bluelight emission contributed by the ligand and the red-light emission contributed by the Eu^3＋. The mixing of the blue and the red composition provides a synthetic route for a ＂white＂ light material.
