The synthesis and photophysical properties of a ruthenium(II) complex bearing an electron-accepting 2,2';6',2''-terpyridine ligand and an electron-donating N,N'-dimethyl-N,N'-dipyridin-2-ylpyridine-2,6-diamine (ddpd) ligand are presented. The heteroleptic complex is easily prepared isomerically pure and features intense low-energy metal-to-ligand charge-transfer (MLCT) absorption bands and intense room temperature (3)MLCT emission with a long (3)MLCT lifetime. The favorable photophysical properties are due to the strong ligand field imposed by the ddpd ligand.
本文介绍了一种含有电子受体 2,2';6',2''-三联吡啶配体和电子给体 N,N'-二甲基-N,N'-二吡啶-2-基-2,6-二吡啶胺(ddpd)配体的钌(II)配合物的合成及光物理性质。该杂配配合物易于制备,且具有异构体纯的特点,表现出强的低能量金属-配体电荷转移(MLCT)吸收带和强的室温(3)MLCT 发射,且(3)MLCT 寿命长。有利的光物理性质归因于 ddpd 配体所施加的强配体场。
