Title:
HOLE TRANSPORT MATERIAL, PREPARATION METHOD THEREFOR AND ELECTROLUMINESCENT DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/000455
Kind Code:
A1
Abstract:
A hole transport material, a preparation method therefor and an electroluminescent device. The hole transport material has a compound (I) of a structural formula represented by formula (I). The hole transport material takes a bridged dihydrophenazine as a basis, and a series of high mobility hole transport materials suitable for HOMO/LUMO energy levels are synthesized by means of collocation designs of different functional groups. Said material can be applied to an organic electroluminescent device to improve the mobility of a hole transport layer, improving the luminous efficiency of the organic electroluminescent device.
