The invention discloses a homophenylarylamine compound and an organic electroluminescence device comprising the same, belonging to the technical field of semiconductors. The structure of the compound is shown in the general formula (1). The compound of the present invention is trisubstituted with benzene as the central meta-position, and the spirofluorene group is used as the substituent, so it has excellent hole migration ability, hole transport ability, membrane Phase stability and weather resistance; when forming hole transport materials for organic electroluminescent devices by using the new homophenylarylamine compounds, effects such as improved device effects, lower driving voltages, and longer lifetimes can be exhibited. |
