The present invention relates to a novel aryl amine derivative and an organic electroluminescent device using the same. Specifically, the aryl amine derivative of the present invention is composed of tetrahydropyrene as a core, and at the positions 2 and 7 of the tetrahydropyrene, independently, the amine groups -NAr 1 Ar 2 and -NAr 3 Ar 4 are substituted. In this case, the aromatic ring groups X 1 and X 2 are independently substituted or unsubstituted between the tetrahydropyrene and the amine group (-NAr 1 Ar 2 and -NAr 3 Ar 4 ). In addition, the organic electroluminescent device of the present invention is an organic light emitting device comprising (i) an anode, (ii) a cathode, and (iii) one or more organic material layers between the anode and the cathode, and at least one of the one or more organic material layers. One layer comprises the aryl amine derivative. In this case, the layer containing the aryl amine derivative is preferably a hole transport layer. |
