Aromatic amine derivative and organic electroluminescent device using the same

摘要

Provided are: an aromatic amine derivative in which a terminal substituent such as a dibenzofuran ring or a dibenzothiophene ring is bonded to a nitrogen atom directly or through an arylene group or the like; an organic electroluminescence device including an organic thin film layer formed of one or more layers including a light emitting layer and interposed between a cathode and an anode in which a layer of the organic thin film layer contains the aromatic amine derivative by itself or as a component of a mixture, and the device has a long lifetime and high luminous efficiency; and an aromatic amine derivative for realizing the device.

1. An aromatic amine derivative represented by the following general formula (1): where 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 or more of Ar1 to Ar4 each represent a group represented by the following general formula (3): when Ar1 to Ar4 excepting those in the formula (3) represent a substituted or unsubstituted aryl group having 6 to 50 ring-forming carbon atoms, Ar1 to Ar4 each independently represent a group selected from a phenyl group, a 2-methylphenyl group, a 3-methylphenyl group, a 4-methylphenyl group, a 4-ethylphenyl group, a biphenyl group, a 4-methylbiphenyl group, a 4-ethylbiphenyl group, a 4-cyclohexylbiphenyl group, a terphenyl group, a 3,5-dichlorophenyl group, a naphthyl group, a 5-methylnaphthyl group, an anthryl group, a pyrenyl group, a chrysenyl group, a fluoranthenyl group, and a perylenyl group, where 1 represents an integer of 0 to 7, X represents oxygen (O), sulfur (S), or selenium (Se), 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 1 represents 2 or more, 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) is bonded to a five-membered ring portion including X is excluded.
