We synthesized 3,6-diarylcarbazole (CBZ) derivatives and investigated their thin-film optical (i.e., absorption, fluorescence and phosphorescence) properties and electroluminescence characteristics. We fabricated phosphorescent organic light-emitting diodes (OLEDs) employing CBZ derivatives as the host and fac-tris(2-phenypyridine)iridium [Ir(ppy)3] as the guest at a doping concentration of 6 wt %. These devices exhibited maximum external quantum efficiencies (ηext) in the range 1 to 11%, depending on the host. In particular, the OLED with CBZ7 as the host exhibited the highest ηext of 11.2% and a maximum power conversion efficiency (ηenergy) of 25 lm/W.
