Aromatic amine derivative organic electroluminescent materials and their devices |
| abstract |
Aromatic amine derivative organic electroluminescent materials and devices thereof are disclosed. The compound is a pyrene compound substituted by an aromatic amine, wherein a substituent is introduced at the N-ortho position of an aryl group of the aromatic amine and a (hetero) aryl group containing an ortho-substituted group is introduced at the N-para position, and another The introduction of a substituent at the N-ortho position of an aryl group can increase the conjugation and stability of the molecule while reducing the planarity of each conjugated system of the molecule. The compounds can be used as light-emitting materials in organic electroluminescent devices. These novel compounds can provide better device performance, such as device lifetime and external quantum efficiency. An electroluminescent device and compound formulation are also disclosed. |
