Abstract:
The present invention relates to a novel diamine derivative, a method for preparation thereof, and an organic electronic device using the same. The diamine derivative according to the present invention can serve as a hole injecting, hole transporting, electron injecting, electron transporting, or light emitting material in an organic electronic device including an organic light emitting device. Particularly, it can be used as a light emitting material as used alone, and also serve as a light emitting host, or a light emitting dopant, in particular, a blue light emitting dopant. The organic electronic device according to the present invention exhibits excellent characteristics in terms of efficiency, drive voltage, life time, and stability.
