摘要

我们利用咔唑-三唑衍生物(CbzTAZ)制备了一种高效的蓝色磷光有机发光二极管(OLED)。该CbzTAZ是由空穴传递咔唑和电子传递三唑组成的双极性结构。分别制备了卡唑基mCP主体和三唑基TAZ主体的oled作为参考。与这两种器件的电致发光性能相比，采用CbzTAZ主体的OLED具有更高的电致发光性能，电流效率为46.06 cd/ a，功率效率为39.8 lm/W，外量子效率为21.78%。

Using carbazole-triazole derives host in blue phosphorescent OLEDs

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 %.
