安息香缩苯胺-邻菲咯啉-铕三元配合物的合成及其光致发光

Synthesis and Photoluminescence of N-Benzoin Aniline,1,10-Phenanthroline,and Europium Ternary Complex

合成了新的配体安息香缩苯胺和新的铕配合物Eu(BZA)3phen,并用元素分析(EA),IR,1H NMR和UV对配合物进行了表征;配合物Eu(BZA)3phen在波长310 nm激发下,发出以铕的特征发谢谱线612nm左右为主的强荧光,对应跃迁为5D0→7F2;安息香缩苯胺对铕离子具有敏化作用,是铕配合物的良好配体。

New N-benzoin aniline and Eu（BZA）3phen were synthesized, and they were characterized by EA, IR, ^1H NMR and UV. The Eu（ Ⅲ ） complex spectra were excited at the wavelength of 342 nm, which exhibited a red emissive color, and the Eu characteristic peaks appeared at 592 and 615 nm, respectively. The 615 nm transition showed the strongest emission. N-benzoin aniline sensitizes to Eu ions and it is a good ligand of Eu complex.
