Abstract

A novel orange-red phosphorescent iridium complex PR-24 has been successfully synthesized and characterized. By using this material, we demonstrated the high-efficiency OLED devices. The best efficiency was achieved for a device using PR-24 as the dopant, exhibiting 25.8 cd/A current efficiency, 20.0 lm/W power efficiency and 15.9% EQE at 1000 cd/m2 . Moreover, when using the optimized co-host configuration, PR-24 shows a remarkable lifetime T₅₀ of 211,000 h for an initial luminance of 1000 nits .
