Description

Technical Field

[0001] This application claims the benefit of the filing date of Korean Patent Application No. 10-2022-0079962, filed with the Korean Intellectual Property Office on June 29, 2022, and all of its content is incorporated herein.

[0002] This specification relates to a compound and an organic light-emitting device including the same.

Background Art

[0003] Generally, the organic light-emitting phenomenon refers to the phenomenon of converting electrical energy into light energy using organic substances. An organic light-emitting device using the organic light-emitting phenomenon usually has a structure including an anode, a cathode, and an organic layer therebetween. Here, the organic layer often has a multilayer structure composed of different substances in order to enhance the efficiency and stability of the organic light-emitting device. For example, it can be composed of a hole injection layer, a hole transport layer, a light-emitting layer, an electron transport layer, an electron injection layer, and the like. In such a structure of an organic light-emitting device, when a voltage is applied between the two electrodes, holes are injected into the organic layer from the anode and electrons are injected into the organic layer from the cathode. When the injected holes and electrons combine, an exciton is formed, and light is emitted when this exciton falls back to the ground state again.

[0004] The development of new materials for the organic light-emitting devices as described above has been continuously demanded.

Summary of the Invention

Problems to be Solved by the Invention

[0005] This specification provides a compound and an organic light-emitting device including the same.

Means for Solving the Problems

[0006] This specification provides a compound of Chemical Formula 1 below. [Chemical Formula 1]

Chem.

[0007] Furthermore, one embodiment of this specification provides an organic light-emitting element comprising a first electrode; a second electrode; and one or more organic layers provided between the first electrode and the second electrode, wherein one or more of the organic layers contain the compound described above. [Effect of the Invention]

[0008] The compound according to one embodiment of the present specification can be used in the organic layer of an organic light-emitting device, thereby reducing the driving voltage of the organic light-emitting device and improving the light efficiency. In addition, the lifetime characteristics of the device can be improved due to the thermal stability of the compound. [Brief Description of the Drawings]

[0009] [Figure 1] This shows an example of an organic light-emitting device according to one embodiment of the present specification. [Figure 2] This shows an example of an organic light-emitting device according to one embodiment of the present specification. [Description of Reference Numerals]

[0011] Hereinafter, the present specification will be described in more detail.

[0012] One embodiment of the present specification provides the compound of Chemical Formula 1.

[0013] Chemical formula 1 according to one embodiment of this specification has a substituted or unsubstituted aryl group bonded to the 9-position of anthracene, and naphthofuran bonded to the 10-position via L. Because chemical formula 1 contains at least one deuterium atom, it has structural properties that improve electron and hole mobility and molecular stability. Therefore, organic light-emitting devices containing this are superior in terms of drive voltage, efficiency, and lifetime.

[0014] Furthermore, this specification provides compounds in which at least one hydrogen atom of chemical formula 1 is substituted with deuterium, and organic light-emitting devices containing the same. Since the CD bond of the compounds of the present invention is stronger than the CH bond, the stability of the compounds can be improved. When the chemical decomposition of a luminescent compound involves the breakdown of relatively weak C(sp3)-H bonds, using a CD bond, which is stronger than a CH bond, can further improve the stability of the compound.

[0015] In this case, when alkyl groups are used as electron-donating substituents, the luminescence properties can be effectively tuned. However, the CH bond of the alkyl group introduced at high energy states is broken, accelerating the decomposition of the compound and causing problems with the overall device lifetime. Therefore, when deuterium-substituted alkyl groups are used, the stability of the blue device can be ensured and the luminescence properties can be effectively tuned. Furthermore, when using deuterium with a smaller van der Waals radius, the steric hindrance is reduced compared to conventional alkyl groups, thus improving conjugation.

[0016] Throughout this specification, the term “these combinations” as used in any Markush expression means one or more mixtures or combinations selected from the group of components described in the Markush expression, and includes one or more selected from the group of components.
