  • Organic compound based on triazine and benzoxazole and application thereof in organic electroluminescent device
    Patent number: 11555018
    Abstract: Disclosed are an organic compound based on triazine and benzoxazole and an application thereof in an OLED device. The compound of the present application has a relatively high glass transition temperature and molecular thermal stability, is low in absorption and high in refractive index in the field of visible light, and is capable of effectively improving the light extraction efficiency of an OLED device when applied to a capping layer of the OLED device; with a deep HOMO energy level and high electronic mobility, the compound of the present application can be used as the hole blocking layer or the electron transport layer material, so that the recombination degree of the hole and the electron in the light-emitting layer can be improved, and thus the light-emitting efficiency of the OLED device can be enhanced and the service life of the OLED device can be prolonged.
