摘　　要：合成了新的可聚合的β-二酮(MADBM)及其铕配合物Eu(MADBM)3phen,并用元素分析(EA)、IR、1HNMR,XPS和UV对配合物进行了表征;配合物Eu(MADBM3phen在波长340nm激发下,发出以铕的特征发射谱线615nm左右为主的强荧光,对应跃迁为5D0→7F2;MADBM对铕离子具有强烈的敏化作用,是铕离子的良好配体并具有可聚合性。Novel β-diketotate（MADBM） and Eu（MADBM）3 phen were synthesized and they were characterized by EA, IR.^1HNMR.XPS and UV. The Eu（Ⅲ） complex spectra were excitated by a wavelength with 340nm , it exhibited a red emissive color and the Eu characteristic peaks were at 592. 615nm, 615nm transition showed the strongest emission. Novel β-diketotate strongly sensitized to Eu ions and it was a good and polymeric ligand of Eu-complex.
