Abstract
The present disclosure provides a hole transporting material, a method for preparing the same, and an electroluminescent device. The hole transporting material includes a compound of formula (I): A series of the hole transport materials with suitable HOMO/LUMO energy levels are synthesized by using bridged dihydrophenazine as a basis and different functional groups. Such materials can be applied to an organic electroluminescent device to improve mobility of a hole transport layer and thus improve luminous efficiency of the organic electroluminescent device.
