AROMATIC AMINE DERIVATIVE AND ORGANIC ELECTROLUMINESCENT ELEMENT EMPLOYING THE SAME

摘要

Provided are an aromatic amine compound represented by the following Formula (1) and an organic electroluminescent element which has at least one organic thin film layer containing the above aromatic amine derivative in the form of a single component. The organic electroluminescent element described above has a high luminescent efficiency even at a low voltage and a long life. It can emit blue light even at high temperatures. In Formula (1), Ar<1> and Ar<2> each represent naphthyl and the like; Ar<3> to Ar<6> each represent phenyl, naphthyl, phenanthryl and the like; Ar<7> to Ar<10> each represent 1,4-phenylene and the like; L represents a single bond and the like; provided that the conditions of (1) and/or (2) are satisfied: (1) at least one of Ar<3> to Ar<6> is a condensed aryl group having 10 to 50 nuclear carbon atoms and (2) at least one of Ar<1> and Ar<2> is a condensed aryl group having 12 to 50 nuclear carbon atoms.
