Abstract
The present specification provides a compound of chemical formula 1 and an organic electronic device comprising the same.
Description
Technical Field
The present specification claims priority to korean patent application No. 10-2018-0039760, filed on 5.4.2018 to the korean patent office, the entire contents of which are incorporated herein.
The present description relates to compounds and organic electronic devices comprising the same.
Background
As a representative example of the organic electronic device, there is an organic light emitting device. In general, the organic light emitting phenomenon refers to a phenomenon of converting electric energy into light energy using an organic substance. An organic light emitting device using an organic light emitting phenomenon generally has a structure including an anode and a cathode with an organic layer therebetween. Here, in order to improve the efficiency and stability of the organic light emitting device, the organic layer is often formed of a multilayer structure composed of different materials, and may be formed of, for example, a hole injection layer, a hole transport layer, a light emitting layer, an electron transport layer, an electron injection layer, or the like. With the structure of such an organic light emitting device, if a voltage is applied between both electrodes, holes are injected from the anode to the organic layer, electrons are injected from the cathode to the organic layer, excitons (exitons) are formed when the injected holes and electrons meet, and light is emitted when the excitons are transitioned to the ground state again.
Most of the substances used in organic light-emitting devices are pure organic substances or complex compounds of organic substances and metals. The materials used in the organic light emitting device may be classified into a hole injecting material, a hole transporting material, a light emitting material, an electron transporting material, an electron injecting material, and the like according to the use. Here, as the hole injecting substance or the hole transporting substance, an organic substance having p-type properties, that is, an organic substance which is easily oxidized and has an electrochemically stable state at the time of oxidation is mainly used. On the other hand, as the electron injecting substance or the electron transporting substance, an organic substance having an n-type property, that is, an organic substance which is easily reduced and has an electrochemically stable state at the time of reduction is mainly used. The light-emitting layer material is preferably a material having both p-type and n-type properties, that is, a material having a stable form in both an oxidized state and a reduced state, and is preferably a material having high light emission efficiency in converting excitons into light when they are formed.
In order to fully exhibit the excellent characteristics of the organic light-emitting device, development of a substance constituting an organic layer in the device is continuously required.
