The invention provides an organic semiconductor material containing carbazole, a preparation method thereof, and an organic electroluminescent device. The organic semiconductor material is represented in the description as a compound P, and the structure of Ar is represented in the description. The compound P is prepared through a Suzuki coupling reaction. The material contains carbazole groups and dibenzothiophene, fluorene or dibenzofuran groups, and thus has a good carrier transport property and high thermostability, so the service life of luminescent device is prolonged. |
