The present invention relates to an organic electroluminescent material, its intermediate and application. In the organic electroluminescent material of the present invention, an aryl group and a -benzoxazole group are added in the molecule, and the electron mobility and transition rate are improved, and the organic electroluminescent material of the present invention is applied to the function of an organic electroluminescent device. When the layer is formed, the performance of the organic electroluminescent device can be improved. |
