Aromatic amine derivative and organic electroluminescent device using the same

An organic electroluminescence device, comprising an organic thin film layer formed of one or more layers comprising a light emitting layer and interposed between a cathode and an anode, wherein the light emitting layer comprises a light emitting material that is an aromatic amine derivative represented by formula (1) or a doping material that is an aromatic amine derivative represented by formula (1):

• wherein:
• Ar0 represents a substituted or unsubstituted pyrenylene group, wherein the optional substituent is an unsubstituted group selected from an aryl group having 6 to 50 ring carbon atoms and an alkyl group having 1 to 50 carbon atoms;
• Ar2, and Ar4 each independently represent a substituted or unsubstituted phenyl group or a substituted or unsubstituted naphthyl group;
• and
• Ar1 and Ar3 each independently represent a group represented by formula (3):
• wherein:
• n represents 0:
• 1 represents 0 or 1;
• X represents oxygen or sulfur;
• Ar represents a substituted or unsubstituted arylene group having 6 to 60 ring-forming carbon atoms;
• and
• R represents an unsubstituted group selected from a methyl group, an ethyl group, a n-propyl group, an isopropyl group, a n-butyl group, a t-butyl group, a phenyl group, and a naphthyl group;
• and
• wherein:
• —NAr1Ar2 and —NAr3Ar4 are bonded to 1- and 6-positions of the pyrenylene group, respectively or —NAr1Ar2 and —NAr3Ar4 are bonded to 2- and 7-positions of the pyrenylene group, respectively.
