Title:
TRIARYLAMINE DERIVATIVE AND ORGANIC ELECTROLUMINESCENT DEVICE THEREOF
Document Type and Number:
Japanese Patent JP2022189817
Kind Code:
A
Abstract:
To provide an organic electroluminescent device having low driving voltage, high luminescence efficiency, and a long service life.SOLUTION: A triarylamine derivative having a structure represented by the following formula has a high triplet energy level, high hole mobility, a high refractive index and good film formability and thermal stability. When used in an organic electroluminescent device, it can effectively reduce the driving voltage of the organic electroluminescent device, improve the luminescence efficiency, and extend the service life of the device.SELECTED DRAWING: Figure 1
