AROMATIC AMINE DERIVATIVE AND ORGANIC ELECTROLUMINESCENT DEVICES CONTAINING THE SAME
-
Paragraph 0166-0167, (2021/03/03)
To further develop a fluorescent light emitting material so as to obtain a higher element efficiency, a longer lifetime of the device, and more blue emission.SOLUTION: The invention discloses aromatic amine derivative, and an organic electroluminescent device including the same. In a structure, fluorene/silafluorene groups with ortho-substituents are introduced into the aromatic amine derivative, therefore the aromatic amine derivative can be used as light-emitting materials in a light-emitting layer of the organic electroluminescent device. These novel compounds can provide better device performance.SELECTED DRAWING: None
