[0002] CROSS-REFERENCE TO RELATED APPLICATIONS

[0003] This application claims priority to and the benefit of Korean Patent Application No. 10-2015-0147537 filed on October 22, 2015, in the Korean Intellectual Property Office, the disclosure of which is incorporated herein in its entirety by reference. Technical Field

[0004] One or more aspects of embodiments of the present disclosure are directed to a compound, an organic light-emitting device including the same, and a display apparatus. Background Art

[0005] Organic light-emitting devices are self-luminous devices that have wide viewing angles, high contrast, short response times, and excellent brightness, driving voltage, and / or response speed characteristics, and can produce full-color images.

[0006] The organic light-emitting device may include a first electrode arranged (e.g., placed) on a substrate, and a hole transport region, a light-emitting layer, an electron transport region, and a second electrode sequentially arranged on the first electrode.

Carriers such as holes and electrons may then recombine in the light-emitting layer to generate excitons. These excitons transition from an excited state to a ground state, thereby generating light.

[0051] A compound including an azapine moiety, which is a nitrogen-containing 7-membered ring compound, can be used as a charge transport material for electrophotography or an organic light-emitting device. Among such compounds, an ethylene-based compound including an azapine moiety, a hydrazone compound having a benzazepine skeleton, and / or a compound having two or more benzazepine moieties can be used in a hole transport layer of an organic device.

[0052] Various compounds including an azapine moiety can be used as phosphorescent hosts, fluorescent hosts, dopants and / or materials for electron transport layers, and can also be included in hole transport layers. For example, azapine-containing arylamine compounds have been used as materials for hole transport layers.

[0053] However, monoamine or diamine derivatives with two or more azepine groups can have low efficiency and relatively short life when they are used as hole transport materials. Due to these characteristics, such monoamine or diamine derivatives are not commercially available. Therefore, efforts have been made to use other arylamine derivatives to develop hole injection materials with low voltage, high efficiency and long life.

[0054] Recently, in order to improve the efficiency of an organic light-emitting device and to increase the efficiency of singlet exciton generation due to triplet-triplet coupling (TTF), which effectively uses excitons generated in a light-emitting layer, a first hole transport layer having a conventional triplet energy level and a second hole transport layer having a triplet energy level higher than the conventional triplet energy level have been described. For example, various compounds can be used for such a second hole transport layer.

[0055] In an embodiment of the present disclosure, a monoamine compound (eg, a compound including one azapine moiety) is used as a hole transport material to improve characteristics of an organic light-emitting device.

[0383] Synthetic intermediate A-17

[0384] 2.86g (6.0mmol) of intermediate A-1' was dissolved in 20mL THF. Then, 2.4mL n-BuLi (2.5 moles (M) in hexane) was slowly added thereto at a temperature of -78°C, and the resulting mixture was stirred at the same temperature for about 1 hour. 1mL (9.0mmol) of trimethyl borate was added dropwise to the solution obtained at the same temperature, and the solution was then returned to room temperature and stirred for about 3 hours. 20mL of water and 10mL of saturated aqueous ammonium chloride solution were sequentially added to the reaction solution obtained, and then stirred for about 1 hour. Three extraction processes were carried out using 30mL of ether. The organic layer obtained was obtained by using MgSO 4 Drying was performed. Next, the solvent was removed therefrom by evaporation. The obtained residue was separated and purified by silica gel column chromatography to obtain 2.28 g of Intermediate A-17 (yield: 89%). The obtained compound was identified by LC-MS.
