Description

Compound Containing Indoloacridine Derivative and Organic Electronic Device Using The Same, and Terminal of the Same {Compound Containing Indoloacridine And Organic Electronic Element Using The Same, Terminal Thereof}

The present invention relates to a compound comprising an indolo acridine derivative, an organic electric device using the same, and a terminal thereof.

In general, organic light emission phenomenon refers to a phenomenon in which an organic material is used to convert electric energy into light energy. An organic electric device using an organic light emitting phenomenon generally has a structure including an anode, an anode, and an organic material layer therebetween. In this case, 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 electric device, for example, it may be made of a hole injection layer, a hole transport layer, a light emitting layer, an electron transport layer and an electron injection layer.

Materials used as the organic material layer in the organic electric element may be classified into light emitting materials and charge transport materials, such as hole injection materials, hole transport materials, electron transport materials, electron injection materials, and the like, depending on their functions. The light emitting material may be classified into a polymer type and a low molecular type depending on the molecular weight, and may be classified into a phosphorescent material derived from singlet excited state of electrons and a phosphorescent material derived from the triplet excited state of electrons . In addition, the light emitting material may be classified into blue, green, and red light emitting materials and yellow and orange light emitting materials required to achieve a better natural color according to the light emitting color.

On the other hand, when only one material is used as a light emitting material, there arises a problem that the maximum light emission wavelength shifts to a long wavelength due to intermolecular interaction, the color purity decreases, or the efficiency of the device decreases due to the light emission attenuating effect. A host / dopant system may be used as the light emitting material in order to increase the light emitting efficiency through the light emitting layer. The principle is that when a small amount of dopant having an energy band gap smaller than that of a host forming the light emitting layer is mixed in the light emitting layer, excitons generated in the light emitting layer are transported to the dopant, thereby producing high-efficiency light. At this time, since the wavelength of the host is shifted to the wavelength band of the dopant, the desired wavelength light can be obtained depending on the type of the dopant used.

In order to fully exhibit the excellent characteristics of the above-described organic electroluminescent device, a material forming the organic material layer in the device, such as a hole injection material, a hole transport material, a light emitting material, an electron transport material, an electron injection material, etc., is supported by a stable and efficient material. Although this should be preceded, the development of a stable and efficient organic material layer for an organic electric element has not yet been made sufficiently, and therefore, the development of new materials is continuously required.

The present inventors have found a compound containing an indoloacridin derivative having a novel structure, and also found that when the compound is applied to an organic electric device, the luminous efficiency, stability and lifetime of the device can be greatly improved. .

Accordingly, an object of the present invention is to provide a compound comprising a novel indolo acridine derivative, an organic electric device using the same, and a terminal thereof.
