- Aromatic amine derivative, polymer, mixture, composition and organic electronic device
-
The invention relates to an aromatic amine derivative, a polymer, a mixture, a composition and an organic electronic device. The aromatic amine derivative has the general formula shown in (I) which isdescribed in the description, the fluorescence emission wavelength of the aromatic amine derivative is short wavelength, its luminescence spectrum has narrow half-peak width, so it has dark blue fluorescence emission, excellent thermal stability and high luminescence efficiency. It has been tested that the organic electronic devices fabricated by the aromatic amine derivatives have good luminousefficiency and long device life.
