Abstract

New iridium complexes that have carbonyl group were synthesized and demonstrated various red light emission in organic light-emitting diodes (OLEDs). The maximum luminance of $57000{\sim}15300\;cd/m^2$ at 15 V and the luminance efficiency of 22.8~5.6 cd/A at $20\;mA/cm^2$ were achieved respectively. The peak wavelength of the electroluminescence were at 570~604 nm and the device also showed a stable color chromaticity with various voltages.
