ARYL AMINE DERIVATIVE AND ORGANIC ELECTROLUMINESCENCE DEVICE USING THE SAME

摘要

Disclosed are a novel aryl amine derivative and an organic electroluminescent device using the same. More specially, the aryl amine derivative is a compound comprising a tetrahydropyrene core, amine groups (-NAr1Ar2 and -NAr3Ar4) each independently substituted at 2 and 7 positions of the tetrahydropyrene, and aromatic ring groups (X1 and X2) each independently substituted or unsubstituted between the tetrahydropyrene core and the amine groups (-NAr1Ar2 and -NAr3Ar4). Further, provided is an organic electroluminescent device comprising (i) an anode, (ii) a cathode, and (iii) one or more organic layers between the anode and the cathode, at least one of the one or more organic layers comprising the aryl amine derivative. Preferably, the organic layer comprising the aryl amine derivative is a hole transport layer.
