신규한 유기 발광 화합물 및 이를 포함하는 유기 전계 발광 소자{Novel organic electroluminescent compounds and organic electroluminescent device using the same}Novel organic electroluminescent compounds and organic electroluminescent device using the same

본 발명은 신규한 유기 발광 화합물 및 이를 포함하는 유기 전계 발광 소자에 관한 것으로, 상세하게는 본 발명에 따른 유기 발광 화합물은 하기 화학식 1의 화합물인 것을 특징으로 한다.The present invention relates to a novel organic light emitting compound and an organic electroluminescent device comprising the same, in detail, the organic light emitting compound according to the present invention is characterized in that the compound of formula (1).

[화학식 1][Formula 1]

Figure 112009044439287-PAT00002

유기EL소자는 보통 anode/HIL/HTL/EML/ETL/EIL/cathode로 구성되는데 발광층(EML)을 어떻게 형성하느냐에 따라 청색, 녹색, 적색의 유기 전기 발광 소자를 각각 구현할 수가 있다. The organic EL device is usually composed of anode / HIL / HTL / EML / ETL / EIL / cathode. The organic electroluminescent device of blue, green, and red can be realized depending on how the emission layer (EML) is formed.

발광재료는 기능적인 측면에서 호스트 재료와 도판트 재료로 구분될 수 있는 데 일반적으로 EL 특성이 가장 우수한 소자 구조로는 호스트에 도판트를 도핑하여 발광층을 만드는 것으로 알려져 있다. 최근에 고효율, 장수명 유기 EL 소자의 개발이 시급한 과제로 대두되고 있으며, 특히 중대형 OLED 패널에서 요구하고 있는 EL 특성 수준을 고려해 볼 때 기존의 발광재료에 비해 매우 우수한 재료의 개발이 시급한 실정이다.The light emitting material can be classified into a host material and a dopant material in terms of its functional properties. In general, a device structure having the best EL characteristics is known to form a light emitting layer by doping a host with a dopant. Recently, the development of high efficiency and long life organic EL devices has emerged as an urgent task, and considering the level of EL characteristics required in medium and large OLED panels, it is urgent to develop materials that are much superior to existing light emitting materials.

한편, 청색 재료의 경우, 이데미쓰-고산의 DPVBi 이후로 많은 재료들이 개발되어 상업화되어 있으며, 이데미쓰-고산의 청색 재료 시스템과 코닥의 다이나프틸안트라센(dinaphthylanthracen), 테트라(t-부틸)페릴렌(tetra(t-butyl)perlyene) 시스템 등이 알려져 있으나, 아직도 많은 연구 개발이 이루어져야 할 것으로 판단된다. 현재까지 가장 효율이 좋다고 알려진 이데미쓰-고산의 디스트릴(distryl)화합물의 시스템은 파워 효율의 경우, 6 lm/W이고, 소자 수명이 30,000 시간 이상으로 좋기는 하나, 색상이 풀컬러디스플레이로 채용하기에는 부적합한 스카이-블루이다. 일반적으로 청색 발광은 발광 파장이 장파장 쪽으로 조금만 이동해도 발광 효율 측면에서는 유리해지나, 순청색을 만족시키지 못해 고품위의 디스플레이에는 적용이 쉽지 않은 문제점을 갖고 있어서, 색순도, 효율 및 열안정성에 대한 연구 개발이 시급한 부분이라고 하겠다.On the other hand, in the case of blue materials, many materials have been developed and commercialized since Idemitsu-Alpine DPVBi, and Idemitsu-Alpine's blue material system, Kodak's dinaphthylanthracen, tetra (t-butyl) fe Although a tetra (t-butyl) perlyene system is known, much research and development is still required. The system of Idemitsu-high acid disryl compound, which is known to be the most efficient to date, is 6 lm / W for power efficiency, and the device life is over 30,000 hours, but the color is adopted as a full color display. Unsuitable sky-blue below. In general, blue light emission is advantageous in terms of light emission efficiency even when the light emission wavelength is shifted to a longer wavelength, but it is not easy to apply to high-quality displays because it does not satisfy pure blue color, and thus research and development on color purity, efficiency and thermal stability It is an urgent part.

고효율, 장수명의 호스트 재료 개발을 위해 다양한 골격을 가진 디스피로-프롤렌-안트라센(TBSA), 터-스피로플로렌(TSF), 비트라이페닐렌(BTP) 등이 개발되었으나 역시 색순도 및 발광효율은 만족할 만한 수준은 아니었다.In order to develop high-efficiency and long-life host materials, disspiro-prolene-anthracene (TBSA), ter-spirofluorene (TSF), and vitriphenylene (BTP) with various skeletons have been developed. It was not satisfactory.

또한, 녹색 형광 재료로는 Alq를 호스트로 하여, 도판트로는 쿠마린 유도체, 퀴나크리돈 유도체, DPT 등을 수 내지 십수 % 정도로 도핑을 하는 시스템이 개발되어 널리 쓰이고 있다. 그러나, 이들 종래의 발광재료는 초기 발광효율의 경우, 상용화 가능한 수준의 성능을 보이나, 초기 효율 저하가 두드러지며 수명 측면에서 상당한 문제점을 보이고 있어, 대화면의 고성능 패널에서는 채택하기가 힘든 한계를 보이고 있다.In addition, a system for doping coumarin derivatives, quinacridone derivatives, DPT, and the like with about 10 to 10% has been developed and widely used as a green fluorescent material using Alq as a host. However, these conventional light emitting materials show a commercially available level of performance in the case of the initial luminous efficiency, but the initial efficiency decreases remarkably and shows considerable problems in terms of lifespan. .

또한, OLED 소자에서의 수명 측면에서도 결코 만족할만한 수준이 되질 못하여 더욱 안정되고, 더욱 성능이 뛰어난 호스트 재료의 개발이 요구되고 있다.In addition, in terms of lifespan in OLED devices, they are never satisfactory, and development of a more stable and more excellent host material is required.

본 발명 목적은 상기한 문제점들을 해결하기 위하여 기존의 호스트 재료보다 발광 효율 및 소자 수명이 좋으며, 적절한 색좌표를 갖는 우수한 골격의 유기 발광 화합물을 제공하는 것이며, 또 다른 목적으로서 상기 유기 발광 화합물을 발광 재료로서 채용하는 고효율 및 장수명의 유기 전계 발광 소자를 제공하는 것이다. SUMMARY OF THE INVENTION An object of the present invention is to provide an organic light emitting compound having an excellent luminescence efficiency and device life, and having an appropriate color coordinate, to solve the above problems, and having an appropriate color coordinate. To provide a high efficiency and long life organic electroluminescent device employed as.

본 발명은 하기 화학식 1로 표시되는 유기 발광 화합물 및 이를 포함하는 유기 전계 발광 소자에 관한 것으로서, 본 발명에 따른 유기 발광 화합물은 발광효율이 좋고 재료의 색순도 및 수명특성이 뛰어나 구동수명이 매우 우수한 OLED 소자를 제조할 수 있는 장점이 있다.The present invention relates to an organic light emitting compound represented by the following Chemical Formula 1 and an organic electroluminescent device comprising the same, the organic light emitting compound according to the present invention has excellent luminous efficiency and excellent color purity and life characteristics of the material OLED very excellent driving life There is an advantage to manufacture the device.
