中文摘要: |
利用环金属配体2-(2’,4’-二氟苯基)-4-甲基吡啶(dfpmpy)和辅助配体5-(三氟甲基)-2-吡啶甲酸(tfmpic)合成了一个铱配合物[Ir(dfpmpy)2(tfmpic)],并测定了该配合物的光物理和电化学性质。在乙腈溶液中,配合物发射黄色磷光,其最大波长位于554 nm,理论计算表明其磷光来自于金属和环金属配体到辅助配体的电荷转移跃迁(3MLCT 或 3LLCT)。 |
英文摘要: |
An iridium complex [Ir(dfpmpy)2(tfmpic)] with 2-(2’,4’-difluorophenyl)-4-methylpyridine (dfpmpy) as cyclometalated ligand and 5-(trifluoromethyl)-2-pyridinecarboxylic acid (tfmpic) as ancillary ligand have been prepared, and photophysical and electrochemical properties has been investigated. In degassed CH3CN solution, this complex exhibits yellow light emission with a peak wavelength of 554 nm, which was attributed to 3MLCT or 3LLCT states. |
