A series of bipolar carbazole compounds has been synthesized as the new host materials for blue phosphorescent organic light emitting diodes (OLED). By the strategy of twisted conformation with single-benzene-connected molecular design, the π conjugation is interrupted which successfully maintains the large energy gap. The photophysics and electrochemical properties were investigated, and these compounds are characterized as high triplet energy host materials in PhOLED.
The device with the host of compound 5 and the guest of FIpic exhibited the turn on voltage at 40 mA/cm2 of 10.08 V, luminance of 10211 cd/m2, max. current efficiency of 47.1 cd/A at 4 V, power efficiency of 41.2 lm/W at 3.5 V and the external quantum efficiency of 20.18 %.
