The invention discloses an aza carbazole OLED (organic light emitting diode) material as well as a preparation method and application thereof. A general structural formula of the aza carbazole OLED material is shown in a formula I as shown in the description. The OLED material has the advantages that carrier transmission efficiency can be improved, and luminous efficiency of a device can also be improved; substituent groups R1 and R2 are introduced in a compound molecule, HOMO (highest occupied molecular orbit) value of an OLED material molecule, molecular stability and glass transition temperature of a material are improved, injection of a hole is facilitated, and the OLED material is excellent in performance; and a synthesis route of the OLED material is simple and easy to operate, reaction yield is high, preparation cost of the OLED material can be reduced, and an industrial prospect is good. |
