An aromatic amine derivative represented by the following general formula (I), an organic electroluminescent element containing the aromatic amine derivative, and an organic electroluminescent material containing the aromatic amine derivative and a solvent as an organic electroluminescent material Provided are an organic electroluminescent device that has a long lifetime, high luminous efficiency, and high blue color emission, and an aromatic amine derivative and an organic electroluminescent material-containing solution that realize the same. [Wherein, R 1 to R 2 represent a hydrogen atom, an alkyl group, or an aryl group, and R 3 to R 6 represent an alkyl group, an aryl group, or a heterocyclic group. Ar 1 to Ar 2 are an arylene group, a divalent heterocyclic group, or a group represented by the general formula (A). {In Formula (A), Ar 3 and Ar 4 represent an arylene group or a divalent heterocyclic group, and R 7 represents an alkylene group, —O—, —S—, —SO 2 —, —SiR 8 R 9 −, —NR 10 — (R 8 , R 9 and R 10 each represents an alkyl group or an aryl group)} a and b are each independently an integer of 1 to 3; ] |
