Abstract
An organic electroluminescent material and a device thereof are disclosed. The organic electroluminescent material uses a compound having a novel carbazole structure, and can be used as hole blocking material, host material in an electroluminescent device. These novel compounds can provide better device performance, such as obtaining device performance of very low driving-voltage, high efficiency, and long lifetime.
