【발명의 배경이 되는 기술】 [Technique to become background of invention]
일반적으로 유기 발광 현상이란 유기 물질을 이용하여 전기에너지를 빛에너지로 전환시켜주는 현상을 말한다. 유기 발광 현상을 이용하는 유기 발광소자는 넓은 시야각， 우수한콘트라스트, 빠른 응답 시간을 가지며， 휘도， 구동 전압 및 응답속도특성이 우수하여 많은 연구가진행되고 있다. 유기 발광 소자는 일반적으로 양극과 음극 및 상기 양극과 음극 사이에 유기물 층을 포함하는 구조를 가진다. 상기 유기물 층은 유기 발광 소자의 효율과 안정성을 높이기 위하여 각기 다른 물질로 구성된 다층의 구조로 이루어진 경우가 많으며， 예컨대 정공 주입층, 정공 수송층, 발광층， 전자수송층, 전자 주입층 등으로 이루어질 수 있다. 이러한 유기 발광 소자의 구조에서 두 전극 사이에 전압을 걸어주게 되면 양극에서는 정공이, 음극에서는 전자가 유기물 층에 주입되게 되고， 주입된 정공과 전자가 만났을 때 엑시톤 (6X0^011)이 형성되며, 이 엑시톤이 다시 바닥상태로 떨어질 때 빛이 나게 된다. 상기와 같은 유기 발광 소자에 사용되는 유기물에 대하여 새로운 재료의 개발이 지속적으로 요구되고 있다. 2019/209031 1»（：1^1{2019/004969 In general, organic light emitting phenomenon refers to a phenomenon of converting electrical energy into light energy using an organic material. The organic light emitting device using the organic light emitting phenomenon has a wide viewing angle, excellent contrast, fast response time, excellent brightness, driving voltage and response speed characteristics, many studies have been conducted. The organic light emitting device generally has a structure including an anode and a cathode and an organic layer between the anode and the cathode. In order to increase 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 for example, may be formed of a hole injection layer, a hole transport layer, a light emitting layer, an electron transport layer, and an electron injection layer. When the voltage is applied between the two electrodes in the structure of the organic light emitting device, holes are injected into the organic material layer at the anode, and electrons are injected into the organic layer, and excitons (6X0 ^ 011) are formed when the injected holes and the electrons meet each other. When this exciton falls back to the ground, it glows. There is a continuous demand for the development of new materials for organic materials used in such organic light emitting devices. 2019/209031 1 »（： 1 ^ 1 {2019/004969
