Novel organic compounds and organic light emitting diode including the same

The present invention relates to a novel compound that can be used in an organic light emitting device, and more particularly, it can be used as a host material for a light emitting layer in an organic light emitting device, thereby realizing high luminous efficiency, low voltage driving, and long lifespan device characteristics. It relates to a novel heterocyclic compound capable of being and an organic light emitting device comprising the same.

An organic light emitting diode (OLED) is a display using a self-luminescence phenomenon, has a large viewing angle, can be lightweight and compact compared to a liquid crystal display, and has advantages such as a fast response speed. ) is expected to be applied to displays or lighting.

In general, the organic light emitting phenomenon refers to a phenomenon in which electric energy is converted into light energy using an organic material. An organic light emitting device using an organic light emitting phenomenon generally has a structure including an anode and a cathode and an organic material layer therebetween. Here, the organic material layer is often formed of a multi-layered structure composed of different materials in order to increase the efficiency and stability of the organic light emitting device, for example, a hole injection layer, a hole transport layer, a light emitting layer, an electron transport layer, an electron injection layer, and the like. In the structure of the organic light emitting device, when a voltage is applied between the two electrodes, holes are injected into the organic material layer from the anode and electrons from the cathode are injected into the organic material layer. When the injected holes and electrons meet, excitons are formed, and the excitons When it falls back to the ground state, it lights up. Such an organic light emitting device is known to have characteristics such as self-luminescence, high luminance, high efficiency, low driving voltage, wide viewing angle, high contrast, and high-speed response.

A material used as an organic layer in an organic light emitting device may be classified into a light emitting material and a charge transport material, for example, a hole injection material, a hole transport material, an electron transport material, an electron injection material, etc. according to their functions. The light emitting material can be classified into a high molecular type and a low molecular type according to the molecular weight, and can be classified into a fluorescent material derived from a singlet excited state of an electron and a phosphorescent material derived from a triplet excited state of an electron according to the light emission mechanism. .

On the other hand, when only one material is used as a light emitting material, the maximum emission wavelength moves to a longer wavelength due to intermolecular interaction, and there is a problem in that the color purity is lowered or the efficiency of the device is decreased due to the emission attenuation effect. Therefore, increase in color purity and energy A host-dopant system can be used as a luminescent material to increase the luminous efficiency through transition.

The principle is that when a small amount of a dopant having a smaller energy band gap than that of the host forming the emission layer is mixed in the emission layer, excitons generated in the emission layer are transported to the dopant to emit light with high efficiency. In this case, since the wavelength of the host moves to the wavelength band of the dopant, light having a desired wavelength can be obtained according to the type of the dopant used.

Among these light emitting layers, heterocyclic compounds have been recently studied as a host compound, and as a related prior art, Patent Publication No. 10-2016-0089693 (2016.07.28) discloses a structure in which a dibenzofuran ring is bonded to an anthracene ring.

However, despite the fact that various types of compounds for use in the light emitting layer of the organic light emitting device have been prepared including the prior art, it is still applicable for organic light emitting devices, and has high efficiency, low voltage driving, and long life. The need for the development of a compound and an organic light emitting device including the same is a situation that is continuously required.
