- Abstract
- A new series of the carbonylated arylpyridine derived iridium complexes were synthesized and their photophysical and electroluminescent properties were characterized. Multilayer devices with the configuration of ITO / 2-TNATA (60 nm) / NPB(20 nm)/ Ir complexes doped in CBP(30 nm) / BCP(10 nm) / Alq(3)(20 nm) / Lig(2 nm)/ Al(100 nm) were fabricated. In the device employing complex 2 as dopant, the maximum luminance, luminanous efficiency, and power efficiency were 16200 cd/m(2) at 14 V. 12.20 cd/A at 20 mA/cm(2) and 4.26 lm/W at 20 mA/cm(2), respectively, at the CIE coordinates of (0.626, 0.373) at 12.0 V.
