The present invention related to an organic electroluminescent material and organic electroluminescent device thereof. The organic electroluminescent material has the structural formula as shown in formula 1. Compared with a monoamine structure containing an adamantyl group, the diamine structure disclosed in the present invention has higher HOMO energy level and hole mobility, and can exhibit higher efficiency and service life than a monoamine material device. The organic electroluminescent device comprising the organic electroluminescent material has lower driving voltage, and higher luminous efficiency and service life.
