摘要: 用一种星型配体1,3,5-三((4,5-二氮芴-9-肟)甲基))-苯合成了三核铕配合物Eu3(DBM)9(TDMB)(DBM=1,3-二苯基-1,3-丙二酮),合成的配合物用元素分析,红外,氢核磁共振进行了表征。研究了配体与配合物的光物理性质。配合物在固态和溶液中具有不同的发光光谱,在二氯甲烷中分别在612 nm和414 nm有荧光峰,固态时只有红光发射,这一结果显示在固态时从TDMB配体到铕离子的能量传递更有效。 |

Abstract: A starburst ligand 1,3,5-tris((4,5-diazafluoren-9-yliminoxy)methyl))-benzene (TDMB), and corresponding trinuclear Eu(Ⅲ) complex Eu3(DBM)9(TDMB) (DBM=1,3-diphenyl-1,3-propanedionate) were synthesized and chara-cterized by elemental analyses, IR, 1H NMR. Furthermore, the photophysical properties of ligand and its europium complex were investigated. It exhibits different PL spectra in solid state and in solution of Eu3(DBM)9(TDMB). There are two fluorescent peaks at 612 nm and 414 nm in dichloromethane solution of Eu3(DBM)9(TDMB), while in solid state only red emission is observed. This result indicates that efficient energy transfer could take place from TDMB ligand to europium ion in Eu-complex solid. |
