Abstract
The present invention provides a hole transport material, a preparation method thereof, and an electroluminescent device. Through ingenious molecular design, a xanthracene structure is combined with different electron-donating groups to synthesize a series of hole transport materials with a suitable highest occupied molecular orbital (HOMO) energy level and a suitable lowest unoccupied molecular orbital (LUMO) energy level, and a series of high-performance display devices can be manufactured using the hole transport materials provided by the present invention.
