Organic compound taking triazine and benzimidazole as cores and application thereof to organic electroluminescent device

The invention relates to an organic compound taking triazine and benzimidazole as cores and application thereof to an OLED (Organic Light Emitting Diode) device. The compound provided by the invention has relatively high glass transition temperature and molecule thermal stability; the compound has low absorption and high refractive index in the field of visible light; after the compound is applied to a CPL (Circular Polarizing Filter) layer of an OLED device, the light extraction efficiency of the OLED device can be effectively improved; the compound also has a deep HOMO energy level and high electron mobility and can be used as a hole-blocking/electron transferring layer material of the OLED device; and the compound can be used for effectively stopping a hole or energy from being transmitted to one side of an electron layer from a light emitting layer, so that the compounding efficiency of the hole and electrons on the light emitting layer is improved, and furthermore, the luminous efficiency of the OLED device is improved and the service life of the OLED device is prolonged.
