AI Technical Summary
The existing organic light-emitting elements have problems such as high driving voltage, low efficiency and short service life, making it difficult to achieve low voltage driving, high brightness and long service life performance.
By designing a novel compound that ensures excellent molecular arrangement and faster Hall mobility by forming the appropriate highest occupancy molecular orbital (HOMO) and improving π conjugation. In addition, by combining 3 rings with excellent electron resistance on the nitrogen side of the aromatic amine, a higher minimum unoccupied molecular orbital (LUMO) and T1 are formed, electron interception and exciton interception are achieved, thereby optimizing the charge balance and driving stability of the luminescent layer.
Low voltage driving is achieved, luminous efficiency is improved, and the service life of the organic light-emitting element is extended by suppressing attenuation.
