- Abstract
- A series of cyclometalated iridium complexes with 2-fluorenylquinoline derivative ligands were synthesized and their photophysical and electroluminescent properties examined using multilayered, organic light-emitting diodes fabricated with the complexes as dopant materials. In the device containing the complex 3 dopant, the maximum luminance was 20,200 cd/m(2) at 14 V. the luminous and power efficiencies were 14.1 cd/A and 11.0 lm/W, respectively, and the CIE coordinates were (0.65, 035) which were close to saturated red emission.
