摘要
合成了新的配体2-苄基-1,3-二苯基-1,3-丙二酮和新的铕配合物Eu(RDBM)3phen,并用元素分析(EA)I、R和UV对配合物进行了表征;配合物Eu(RDBM)3phen在波长328nm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;2-苄基-1,3-二苯基-1,3-丙二酮对铕离子具有敏化作用,是铕配合物的良好配体。
New 2-benzyl-1,3-diphenyl 1,3-propdione and Eu （RDBM）3phen were synthesized and they were characterized by EA, IR and UV. The Eu（Ⅲ） complex spectra was excitated by a wavelength with 328nm , it exhibited a red emissive color and the Eu characteristic peaks were at 592.615nm, 615 nm transition showed the strongest emission. 2-benzyl-1, 3 diphenyl-1,3-propdione sensitized to Eu ions and it is a good ligand of Eu.
