The invention belongs to the technical field of organic photoelectric materials, and discloses an organic small molecule luminescent material and an organic electroluminescence device prepared therefrom. The organic small molecule luminescent material uses 9,9-dimethyl-10-phenylacridine or 10-phenylphenoxazine as the electron-donating unit, through the 2-position of the acridine unit or the phenoxazine The 3 positions of the unit are connected with different electron-withdrawing units, and a series of new high-efficiency organic small molecule light-emitting materials are obtained. The organic small molecule luminescent material of the invention changes the charge transfer characteristics within the material, so that the luminescence peak of the luminescent material is blue-shifted, and can be used as a luminescent layer in an organic electroluminescent device with high device efficiency. |
