Abstract

We fabricated an efficient blue phosphorescent organic light emitting diode (OLED) using our new carbazole-triazole derives (CbzTAZ) host. This CbzTAZ was chemically combine a hole-transporting carbazole moiety and an electron-transporting triazole moiety to be the bipolar behavior. Two OLEDs with carbazole-based mCP host and triazole-based TAZ were fabricated to be the reference. In Comparison with the electroluminance performance of these two devices, the OLED with CbzTAZ host perform a more efficient electroluminance performance, such as a current efficiency of 46.06 cd/A, a power efficiency of 39.8 lm/W and an external quantum efficiency of 21.78 %.
