Description

화합물, 이를 이용한 유기전기소자 및 그 전자 장치{COMPOUND FOR ORGANIC ELECTRONIC ELEMENT, ORGANIC ELECTRONIC ELEMENT USING THE SAME, AND A ELECTRONIC DEVICE THEREOF}BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an organic electroluminescent device,

본 발명은 화합물, 이를 포함하는 유기전기소자 및 그 전자 장치에 관한 것이다.TECHNICAL FIELD [0001] The present invention relates to a compound, an organic electric device including the same, and an electronic device thereof.

일반적으로 유기 발광 현상이란 유기 물질을 이용하여 전기에너지를 빛 에너지로 전환시켜주는 현상을 말한다. 유기 발광 현상을 이용하는 유기전기소자는 통상 양극과 음극 및 이 사이에 유기물층을 포함하는 구조를 가진다. 여기서 유기물 층은 유기전기소자의 효율과 안정성을 높이기 위하여 각기 다른 물질로 구성된 다층의 구조로 이루어진 경우가 많으며, 예컨대 정공주입층, 정공수송층, 발광층, 전자수송층 및 전자주입층 등으로 이루어질 수 있다. 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. Here, in order to increase the efficiency and stability of the organic electronic device, the organic material layer is often formed of a multilayer structure composed of different materials, and 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.

유기전기소자에서 유기물층으로 사용되는 재료는 기능에 따라, 발광 재료와 전하수송 재료, 예컨대 정공주입 재료, 정공수송 재료, 전자수송 재료, 전자주입 재료 등으로 분류될 수 있다. A material used as an organic material layer in an organic electric device may be classified into a light emitting material and a charge transporting material such as a hole injecting material, a hole transporting material, an electron transporting material, and an electron injecting material depending on functions.

한편, 유기전기소자의 수명단축 원인 중 하나인 양극전극(ITO)으로부터 금속 산화물이 유기층으로 침투 확산되는 것을 지연시키며, 소자 구동시 발생되는 주울열(Joule heating)에 대해서도 안정된 특성, 즉 높은 유리 전이 온도를 갖는 정공 주입층 재료에 대한 개발이 필요하다. 또한 정공 수송층 재료의 낮은 유리전이 온도는 소자 구동시에 박막 표면의 균일도가 무너지는 특성에 따라 소자수명에 큰 영향을 미치는 것으로 보고되고 있다. 또한, OLED 소자의 형성에 있어서 증착방법이 주류를 이루고 있으며, 이러한 증착방법에 오랫동안 견딜 수 있는 재료 즉 내열성 특성이 강한 재료가 필요한 실정이다. On the other hand, the diffusion of metal oxide from the anode electrode (ITO), which is one of the causes of shortening the lifetime of the organic electronic device, is delayed, and stable characteristics such as joule heating generated during driving the device, It is necessary to develop a hole injection layer material having a temperature. It is also reported that the low glass transition temperature of the hole transporting layer material significantly affects the lifetime of the device depending on the characteristics of the uniformity of the thin film surface collapsing during device operation. In addition, the deposition method is the mainstream in the formation of OLED devices, and a material that can withstand such a long time, that is, a material having high heat resistance characteristics, is required.

전술한 유기전기소자가 갖는 우수한 특징들을 충분히 발휘하기 위해서는 소자 내 유기물층을 이루는 물질, 예컨대 정공주입 물질, 정공수송 물질, 발광 물질, 전자수송 물질, 전자주입 물질 등이 안정하고 효율적인 재료에 의하여 뒷받침되는 것이 선행되어야 하나, 아직까지 안정하고 효율적인 유기전기소자용 유기물층 재료의 개발이 충분히 이루어지지 않은 상태이며, 따라서 새로운 재료의 개발이 계속 요구되고 있다.In order to sufficiently exhibit the excellent characteristics of the organic electroluminescent device described above, a material constituting the organic material layer in the device, such as a hole injecting material, a hole transporting material, a light emitting material, an electron transporting material, and an electron injecting material is supported by a stable and efficient material However, stable and efficient development of an organic material layer for an organic electric device has not yet been sufficiently developed, and therefore development of a new material is continuously required.

본 발명은 소자의 높은 발광효율, 낮은 구동전압, 고내열성, 색순도 및 수명을 향상시킬 수 있는 화합물, 이를 이용한 유기전기소자 및 그 전자장치를 제공하는 것을 목적으로 한다. It is an object of the present invention to provide a compound capable of improving a high luminous efficiency, a low driving voltage, a high heat resistance, a color purity and a lifetime of the device, an organic electric device using the same, and an electronic device thereof.
