Patent ID: 8518560

Claim:
An aromatic amine derivative represented by the following general formula (1): where Ar 0 represents a substituted or unsubstituted naphthylene group, a substituted or unsubstituted anthracenylene group, a substituted or unsubstituted phenanthrylene group, a substituted or unsubstituted chrysenylene group, a substituted or unsubstituted pyrenylene group, a substituted or unsubstituted benzoanthracenylene group, a substituted or unsubstituted fluoranthenylene group, a substituted or unsubstituted benzofluoranthenylene group, a substituted or unsubstituted perylenylene group, a substituted or unsubstituted coronenylene group, a substituted or unsubstituted picenylene group, a substituted or unsubstituted diphenylanthracenylene group, a substituted or unsubstituted triphenylylene group, a substituted or unsubstituted rubicenylene group, a substituted or unsubstituted phenylanthracenylene group, a substituted or unsubstituted bisanthracenylene group, a substituted or unsubstituted dianthracenylbenzynylene group, and a substituted or unsubstituted dibenzoanthracenylene group, and Ar 1 to Ar 4 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 or more of Ar 1 to Ar 4 each represent a group represented by the following general formula (3): where n represents an integer of 0 to 3, 1 represents an integer of 0 to 7, 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 1 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: in the general formula (3), a case where (R) 1 and (Ar) n are bonded to a five-membered ring portion including X is excluded.
