Abstract
An organic compound and a manufacturing method thereof, and an organic light emitting diode electroluminescent device are provided. The organic compound has a suitable HOMO energy level and a high hole mobility. Compared with traditional hole transport materials, when the organic compound is applied in a hole transport layer of the organic light emitting diode electroluminescent device, the organic light emitting diode electroluminescent device has enhanced maximum current efficiency, maximum external quantum efficiency, and service lifespans.
