Paragraph 0087-0090, (2020/01/24)
To provide an organic EL device having low driving voltage, high luminous efficiency, and particularly a long lifetime by combining various materials for an organic EL device having excellent hole and electron injection/transport performances, electron blocking ability, stability in a thin-film state, and durability as materials for an organic EL device having high luminous efficiency and high durability so as to allow the respective materials to effectively reveal their characteristics. In the organic EL device having at least an anode, a hole injection layer, a hole transport layer, a light emitting layer, an electron transport layer, and a cathode, in this order, the hole injection layer includes an arylamine compound of the following general formula (1) and a radialene derivative of the following general formula (2).

A compound represented by Formula 1. An organic electric element includes a first electrode, a second electrode, and an organic material layer including the compound of Formula 1. The organic material layer include a light emitting layer, a hole transport layer including a compound represented by Formula 2, and an emission-auxiliary layer including the compound represented by Formula 1. When the organic electric element includes the compound in the organic material layer, luminous efficiency, color purity, and life span can be improved.

[Problem] To provide a method of producing an aromatic amino compound by using a primary or secondary amine compound and a halogenated aromatic compound as starting materials, and relying upon the Ullmann reaction, the method being capable of obtaining the highly pure aromatic amino compound in high yields and inexpensively. [Means for Solution] A method of producing an aromatic amino compound by using a primary or secondary amine compound having an aromatic ring group and a halogenated aromatic compound as starting materials, reacting the amine compound with the halogenated aromatic compound in the presence of a copper catalyst and a base so as to produce the aromatic amino compound having a structure in which an aromatic ring group derived from the halogenated aromatic compound is coupled to the amino group of the amine compound, wherein the amine compound and the halogenated aromatic compound are reacted together under a condition where an aromatic oxycarboxylic acid having a hydroxyl group and a hydroxycarbonyl group that are bonded to neighboring carbon atoms, is made present together with the copper catalyst and the base.
