AROMATIC AMINE DERIVATIVE AND ORGANIC ELECTROLUMINESCENT ELEMENT USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide an organic EL element capable of obtaining blue luminescence, and a useful aromatic amine derivative capable of being used for the organic thin film layer of the organic EL element.SOLUTION: Provided is an aromatic amine derivative represented by formula (1): in the formula (1), Rto Rand Rto Rrespectively independently denote a hydrogen atom or a substitutional group, in the general formula (1), Rand Rare represented by general formula (2), and Lto Lrespectively independently denote a single bond, the bivalent residue of an aryl group or the like. In the general formula (2); Ardenotes a monovalent substitutional group having general formula (3) as a partial structure; X denotes an oxygen atom or a sulfur atom; A and B denotes a 6-membered ring. In the general formula (2), Ardenotes an aryl group or a heterocyclic group. The monovalent substitutional group having the general formula (3) as a partial structure has at least one of a fluorine atom or the like.
