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 has been prepared, and its photophysical and electrochemical properties have been investigated. In degassed CH₃CN solution, this complex exhibits yellow light emission with a peak wavelength of 554 nm, which was attributed to the ³MLCT or ³LLCT states.
- 5-(Trifluoromethyl)-2-pyridinecarboxylic acid,
- Iridium complex,
- Yellow light emission
