Abstract
Provided are an organic compound and an application thereof. The compound has a relatively deep LUMO energy level, which may reduce a potential barrier of electron transport, improve an electron injection capability and effectively reduce a voltage of an OLED device. The compounds each have a relatively deep HOMO energy level, which may effectively block holes so that more holes and electrons are recombined in a light-emitting region, achieving relatively high luminescence efficiency. An electron transport layer material and/or a hole blocking layer material suitable for the OLED device can reduce the voltage and power consumption of the device, improve the luminescence efficiency and extend a working lifetime so that the OLED device has better comprehensive performance.
