Description

technical field [0001] The invention relates to an aromatic amine compound and an application thereof, belonging to the technical field of semiconductors. Background technique [0002] OLED photoelectric functional materials can be divided into two categories in terms of usage, namely charge injection transport materials and luminescent materials. Further, charge injection transport materials can also be divided into electron injection transport materials, electron blocking materials, hole injection transport materials and Hole blocking material. In order to make high-performance OLED light-emitting devices, various organic functional materials are required to have good photoelectric properties. For example, as charge transport materials, good carrier mobility and high glass transition temperature are required. [0003] The OLED photoelectric functional material film layer that constitutes an OLED device includes at least two layers of structure, and the OLED device structu...
