Abstract
Provided are an organic compound and an application thereof. The organic compound has a structure represented by Formula I. Through the design of a molecular structure, the organic compound has suitable HOMO and LUMO energy levels, high singlet energy level, good optoelectronic performance, a high glass transition temperature and good thermal stability, easily forms a good amorphous film, and is suitable for the machining and use of an OLED device. The organic compound, when used in the OLED device, may be used as a light-emitting layer material, an electron transport material or a hole blocking material and especially suitable for use as a host material of the light-emitting layer and can effectively improve the luminescence efficiency of the device, improve the device stability, extend lifetime, and reduce an operating voltage and energy consumption so that the OLED device has significantly improved performance such as luminescence efficiency, lifetime and energy consumption.
