Abstracts
Two heteroleptic charged iridium (III) species comprising two cyclometallating ligands and a neutral diimine ligand were synthesized and characterized, namely [(3,4,7,8-tetramethyl-1,10-phenanthroline-N-N')-bis-(2-(2,4-difluorophenyl)-5-(trifluoromethyl)pyridine-C^{6'},N)-iridium (III)]hexafluorophosphate (UM01) and [(3,4,7,8-tetramethyl-1,10-phenanthroline-N-N')-bis-(2-(2',4'-difluoro-phenyl)-1H-pyrazole-C^{6'},N)-iridium (III)]hexafluorophosphate (UM02). Both complexes were used as the blue emitter in OLED and LEC devices. We found that the optimized structure is ITO/PEDOT:PSS/complex:BMIMPF₆(1:1)/Al. The UM01 gave a current efficiency of 1.14 cd A^{-1}, whereas the UM02 shows a better CIE coordination at 0.19, 0.40.
