Provided are an organic electroluminescent material and an organic luminescent device comprising the organic electroluminescent material. The organic electroluminescent material has the structural formula of (I). Compared with a monoamine structure containing an adamantyl group, a diamine structure contained in the present invention has a higher HOMO energy level and hole mobility, and can exhibit a higher efficiency and service life than a monoamine material device. The organic luminescent device comprising the organic electroluminescent material has a lower driving voltage, and a higher luminous efficiency and service life. |
