The invention relates to an organic compound containing pyrene or azapyrene and an application thereof, belonging to the technical field of semiconductors. The structure of the compound provided by the invention is shown in general formula (I): The invention also discloses the application of the above compounds. The organic compound provided by the present invention has strong hole transport ability, and improves the hole injection and transport performance under the appropriate HOMO energy level; under the appropriate LUMO energy level, it also plays the role of electron blocking and improves the excitation The recombination efficiency of the excitons in the light-emitting layer; when used as the light-emitting functional layer material of the OLED light-emitting device, the use of the excitons and the radiation efficiency can be effectively improved with the branch chain within the scope of the present invention. |
