Abstract

Provided are an organic compound and an application thereof. The compound has a relatively deep LUMO energy level and can reduce a potential barrier of electron transport, improve an electron injection ability, and effectively reduce the voltage of an OLED device. Such compounds all have relatively deep HOMO energy levels and can effectively block holes so that more holes and electrons are recombined in a light-emitting region, achieving higher luminescence efficiency. Materials of an electron transport layer and/or a hole blocking layer suitable for the OLED device can reduce the voltage and power consumption, improve the luminescence efficiency, and extend the service life of the device so that the OLED device has better comprehensive performance.
