AROMATIC AMINE DERIVATIVES AND ORGANIC LIGHT EMITTING LAYER AND DIODE COMPRISING THE SAME

摘要

Disclosed are aromatic amine derivatives that can significantly improve material lifetime and luminous efficiency by introducing substituted or unsubstituted, saturated or unsaturated, hexagonal or more polygonal hydrocarbon rings into positions 2, 3, 6 and 7 of anthracene to thereby preventing the crystallization of anthracene, and an organic light emitting layer and an organic light emitting diode comprising the same.
