A novel and highly efficient bis(trifluoromethyl)phenyl functionalized iridium(III) complex is designed and synthesized. The complex shows intensive greenish yellow phosphorescence (525 nm with 563 nm as shoulder), high photoluminescence efficiency (0.90) and moderate full width at half maximum (72 nm). The bulky bis(trifluoromethyl)phenyl moiety introduced into the complex provides the excellent solubility and effective steric hindrance for solution-processed organic light-emitting diodes. The maximum power efficiency and current efficiency of electroluminescence are 4.13 lm/W and 9.54 cd/A, respectively.

Paragraph 0042; 0046; 0048-0049, (2018/09/28)
The invention relates to a yellow-green light pyridylpyridine iridium complex. The complex has a following structural formula shown in the description, wherein R1 can independently be methyl or ethylor tert-butyl or isopropyl or the like, R2 can independently be 3,5-bis(trifluoromethyl)phenyl or 3,5-difluorophenyl or phenyl or 4-fluorophenyl or 4-trifluoromethylphenyl, and an ancillary ligand shown in the description can independently be 2-(3-(trifluoromethyl)-1H-1,2,4-triazol-5-yl)pyridine or pyridine-2-formic acid or acetylacetone. The yellow-green light iridium (III) complex has the advantages of good solubility and yellow-green light emission and can be used as an electroluminescent phosphorescent material and applied to wet-process organic electroluminescent devices.
