Title:
LIGHT-EMITTING LAYER DOPANT OF ORGANIC LIGHT-EMITTING DIODE AND PREPARATION METHOD THEREFOR, AND ELECTROLUMINESCENT DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/237793
Kind Code:
A1
Abstract:
The present invention relates to a light-emitting layer dopant of an organic light-emitting diode and a preparation method therefor, and an electroluminescent device prepared by applying the light-emitting layer dopant. The preparation method for a light-emitting layer dopant is simple in terms of operation, is easily implemented, has a high preparation efficiency, and can prepare a light-emitting layer dopant material with a high purity. Since the electroluminescent device includes the light-emitting layer dopant, phosphorescent luminescence of a light-emitting layer material can be realized, thereby improving the luminous efficiency of an electroluminescent device.
