Aromatic amine derivative and organic electroluminescent device using the same

An aromatic amine derivative represented by the following general formula (1):

• wherein:
• Ar0 represents a substituted or unsubstituted, divalent fused aromatic hydrocarbon group having 10 to 50 ring-forming carbon atoms, and
• Ar1 to Ar4 each independently represent a substituted or unsubstituted aryl group having 6 to 50 ring-forming carbon atoms, a substituted or unsubstituted alkyl group having 1 to 50 carbon atoms, a substituted or unsubstituted cycloalkyl group having 3 to 50 ring-forming carbon atoms, a substituted or unsubstituted aralkyl group having 7 to 50 ring-forming carbon atoms, or a substituted or unsubstituted heterocyclic group having 5 to 50 ring-forming atoms,
• provided that one, two or three of Ar1 to Ar4 each represent a group represented by formula (2):
• wherein:
• n represents an integer of 0 to 3, m represents an integer of 0 to 5,
• X represents oxygen (O), sulfur (S), or selenium (Se), Ar represents a substituted or unsubstituted arylene group having 6 to 60 ring-forming carbon atoms,
• R represents a substituted or unsubstituted aryl group having 6 to 60 ring-forming carbon atoms, a substituted or unsubstituted alkyl group having 1 to 50 carbon atoms, an amino group, a substituted or unsubstituted alkoxy group having 1 to 50 carbon atoms, a substituted or unsubstituted aryloxy group having 6 to 50 ring-forming carbon atoms, a substituted or unsubstituted arylthio group having 6 to 50 ring-forming atoms, a substituted or unsubstituted alkoxycarbonyl group having 1 to 50 carbon atoms, a halogen atom, a cyano group, a nitro group, a hydroxyl group, a silyl group, or a carboxyl group,
• when n or m represents 2 or more, multiple Ar's or multiple R's may be identical to or different from each other, and
• when multiple R's are present, the multiple R's may be bonded to each other to form a saturated or unsaturated, five- or six-membered cyclic structure that may be substituted, provided that:
• when n=0, a five-membered ring portion including X in the general formula (2) is free from being directly bonded to N bonded to Ar0.
