The present invention relates to the field of light-emitting materials, in particular to an organic light-emitting material, a preparation method thereof, and an organic light-emitting device containing the material. The organic light-emitting material provided by the present invention is any one of the following structural formulas: In the above structural formula: R is phenyl or biphenyl; Ar 1 and Ar 2 are each independently selected from substituted or unsubstituted C6-31 aryl or substituted or unsubstituted C12-30 heteroaryl. In the present invention, the hole injection ability/transport ability, high power efficiency and long life are obtained by introducing the arylamine into the acridine ring. The organic electroluminescent device prepared from the organic light-emitting compound of the present invention has excellent current efficiency and power efficiency and long lifetime. The preparation method of the organic light-emitting compound of the present invention has good repeatability and high yield. |
