ORGANIC COMPOUND WITH TRIAZINE AND QUINOXALINE AS CORE AND APPLICATION THEREOF IN OLED

摘要

The present invention relates to an organic compound with triazine and quinoxaline as a core and application thereof in an OLED device. The compound of the present invention is high in glass transition temperature and molecular thermal stability, has low absorption and a high refractive index in the field of visible light, and can effectively improve the light extraction efficiency of the OLED device after being applied to a CPL layer of the OLED device. The compound of the present invention also has a deep HOMO energy level and a high electronic mobility, can be taken as a hole blocking/electron transport layer material of the OLED device, and can effectively block holes or energy from being transmitted to one side of an electron layer from a light emitting layer, so that the recombination efficiency of the holes and electrons on the light emitting layer is improved, the light emitting efficiency of the OLED device is improved, and the service life is prolonged.
