The present invention relates to the technical field of organic light-emitting materials, in particular to an organic light-emitting compound, a preparation method thereof, and an organic electroluminescent device containing the compound. The present invention provides an organic light-emitting compound, which is a combination of acridine-based functional groups with high electron-hole transport efficiency and triarylamines with excellent hole-transport performance to form a type of organic light-emitting compound with high thermal stability and excellent luminous efficiency. The introduction of different substituents can change the electronic transition, so that the luminescence peak position can be adjusted, and the red light device made of the material of the present invention can meet the needs of industrial production. The preparation method of the organic light-emitting compound provided by the present invention is simple and suitable for industrial production, and the compound with better performance can be prepared by adjusting the dosage ratio of reactants, and the reaction time and temperature. The organic light-emitting device provided by the present invention has excellent luminous efficiency, brightness, resolution and long life. |
