Paragraph 0141-0144, (2021/11/10)
The invention discloses an aromatic amine derivative organic electroluminescent material and device. The compound is an aromatic amine substituted pyrene compound, a substituent group is introduced to the N-ortho position of one aryl group of aromatic amine, a (hetero) aryl group containing an ortho substituent group is introduced to the N-para position of the aryl group, and a substituent group is introduced to the N-ortho position of the other aryl group, so that the conjugacy and the stability of molecules can be improved, and the planarity of each conjugated system of the molecules can be reduced. The compound can be used as a luminescent material in an organic electroluminescent device. The novel compounds can provide better device performance, such as device lifetime and external quantum efficiency. An electroluminescent device and a compound formulation are also disclosed.
