Description
본 발명은 신규한 유기 발광 화합물 및 이를 포함하고 있는 유기 전계 발광 소자 에 관한 것이다.The present invention relates to a novel organic light emitting compound and an organic electroluminescent device comprising the same.
표시 소자 중, 전기 발광 소자(electroluminescence device: EL device)는 자체 발광형 표시 소자로서 시야각이 넓고 콘트라스트가 우수할 뿐만 아니라 응답속도가 빠르다는 장점을 가지고 있으며, 1987년 이스트만 코닥(Eastman Kodak)사에서는 발광층 형성용 재료로서 저분자인 방향족 디아민과 알루미늄 착물을 이용하고 있는 유기 EL 소자를 처음으로 개발하였다[Appl. Phys. Lett. 51, 913, 1987].Among the display elements, an electroluminescence device (EL device) is a self-luminous display element that has a wide viewing angle, excellent contrast, and high response speed.Eastman Kodak Co., Ltd. in 1987 An organic EL device using a low molecular aromatic diamine and an aluminum complex as a light emitting layer formation material was first developed [Appl. Phys. Lett. 51, 913, 1987].
유기 EL 소자는 전자 주입 전극(음극) 과 정공 주입 전극(양극) 사이에 형성된 유기막에 전하를 주입하면 전자와 정공이 쌍을 이루어 여기자를 생성한다. 여기자의 비활성시의 발광(인광 또는 형광)을 이용함으로써 빛이 방출된다. 유기 EL 소자는 약 10V의 전압과 약 100∼10,000cd/㎡의 높은 휘도로 편광을 방출하며, 단순히 형광물질을 선택함으로써 파란색에서 빨간색까지의 스펙트럼으로 빛을 방출한다는 특징이 있다. 플라스틱 같은 휠 수 있는(flexible) 투명 기판 위에도 소자를 형성할 수 있을 뿐 아니라, 플라즈마 디스플레이 패널(Plasma Display Panel)이나 무기 EL 디스플레이에 비해 낮은 전압에서 (10V이하) 구동이 가능하고, 전력 소모가 비교적 적으며, 색감이 뛰어나다는 장점이 있다. The organic EL element injects charge into an organic film formed between the electron injection electrode (cathode) and the hole injection electrode (anode) to generate excitons by pairing electrons and holes. Light is emitted by using light emission (phosphorescence or fluorescence) when the excitons are inactive. The organic EL device emits polarized light with a voltage of about 10 V and a high luminance of about 100 to 10,000 cd / m 2, and emits light in a spectrum from blue to red by simply selecting a fluorescent material. The device can be formed on a flexible transparent substrate such as plastic, and can be driven at a lower voltage (less than 10V) compared to a plasma display panel or an inorganic EL display, and has a relatively low power consumption. It has a small and excellent color.
유기 EL 소자에서 발광 효율, 수명 등의 성능을 결정하는 가장 중요한 요인은 발광 재료로서, 이러한 발광 재료에 요구되는 몇 가지 특성으로는 고체상태에서 형광 양자 수율이 커야하고, 전자와 정공의 이동도가 높아야 하며, 진공 증착시 쉽게 분해되지 않아야 하고, 균일한 박막을 형성, 안정해야한다. In organic EL devices, the most important factor that determines the performance of light emission efficiency, lifetime, etc. is a light emitting material. Some characteristics required for such a light emitting material include high quantum fluorescence yield in solid state, and mobility of electrons and holes. It should be high, not easily decomposed during vacuum deposition, and form a stable thin film.
유기 발광 재료는 크게 고분자 재료와 저분자 재료로 나눌 수 있는데, 저분자 계열의 재료는 분자 구조 면에서 금속 착화합물과 금속을 포함하지 않는 순수 유기 발광 재료가 있다. 이러한 발광 재료로는 트리스(8-퀴놀리놀라토)알루미늄 착제 등의 킬레이트 착제, 쿠마린 유도체, 테트라페닐부타디엔 유도체, 비스스타이릴아릴렌 유도체, 옥사다이아졸 유도체 등의 발광 재료가 알려져 있고, 이들로부터는 청색에서 적색까지의 가시 영역 발광을 얻을 수 있다고 보고되었다.Organic light emitting materials can be classified into high molecular materials and low molecular materials. Low molecular materials include pure organic light emitting materials that do not contain metal complexes and metals in terms of molecular structure. As such light emitting materials, light emitting materials such as chelate complexes such as tris (8-quinolinolato) aluminum complexes, coumarin derivatives, tetraphenylbutadiene derivatives, bisstyrylarylene derivatives and oxadiazole derivatives are known. Has been reported to obtain visible region luminescence from blue to red.
풀칼라 OLED 디스플레이의 구현을 위해서는 RGB 3가지의 발광재료를 사용하게 되는데 유기 EL 전체의 특성을 향상시키는데 고효율 장수명의 RGB 발광재료의 개발이 중요한 과제라고 할 수 있다. 발광재료는 기능적인 측면에서 호스트 재료와 도판트 재료로 구분될 수 있는데 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. 이러한 측면에서 호스트 재료의 개발이 해결해야 할 가장 중요한 요소 중의 하나이다. 이때 고체 상태의 용매 및 에너지 전달자 역할을 하는 호스트 물질의 바람직한 특성은 순도가 높아야하며, 진공증착이 가능하도록 적당한 분자량을 가져야 한다. 또한 유리 전이온도와 열분해온도가 높아 열적 안정성을 확보해야하며, 장수명화를 위해 높은 전기화학적 안정성이 요구되며, 무정형박막을 형성하기 용이해야 하며, 인접한 다른 층의 재료들과는 접착력이 좋은 반면 층간이동은 하지 않아야 한다.In order to realize a full color OLED display, three kinds of RGB light emitting materials are used, and development of high efficiency long life RGB light emitting materials is an important task to improve the characteristics of the entire organic EL. The light emitting material can be classified into a host material and a dopant material in terms of its function. In general, a device structure having excellent EL characteristics is known to make 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. In this respect, the development of host materials is one of the most important factors to be solved. In this case, the desirable properties of the host material serving as a solvent and energy transporter in the solid state should be high in purity and have an appropriate molecular weight to enable vacuum deposition. In addition, high glass transition temperature and pyrolysis temperature should ensure thermal stability, high electrochemical stability is required for long life, easy to form amorphous thin film, good adhesion with other adjacent materials, Should not.
유기 EL 소자를 도핑기술을 사용하여 제조하는 경우 여기상태에서 호스트분자로부터 도판트로의 에너지전달은 100%가 되지 못하고, 도판트뿐만 아니라 호스트물질도 빛을 방출하게 된다. 특히 적색발광소자인 경우에는 호스트물질이 도판트보다 가시성이 큰 파장범위에서 빛을 방출하기 때문에 색순도가 호스트물질의 흐린 광방출에 의해 악화된다. 또 실제로 적용하는 경우 발광수명 및 지속성이 개선될 필요가 있다.When an organic EL device is manufactured using a doping technique, energy transfer from the host molecule to the dopant in the excited state is less than 100%, and not only the dopant but also the host material emits light. In particular, in the case of a red light emitting device, since the host material emits light in a wavelength range where visibility is greater than that of the dopant, color purity is deteriorated by light emission of the host material. In addition, the light emission life and the sustainability need to be improved in practical application.
한편, 인광 발광체의 호스트 재료로는 현재까지 CBP가 가장 널리 알려져 있으며, BCP 및 BAlq 등의 정공차단층을 적용한 고효율의 OLED가 공지되어 있으며, 일본의 파이오니어 등에서는 BAlq 유도체를 호스트로 이용한 고성능의 OLED가 공지되어 있다.On the other hand, CBP is the most widely known host material for phosphorescent emitters, and high-efficiency OLEDs using a hole blocking layer such as BCP and BAlq are known, and high-performance OLEDs using BAlq derivatives as a host are known in Pioneer, Japan. Is known.
그러나 기존의 재료들은 발광 특성 측면에서는 유리한 면이 있으나, 유리전이온도가 낮고 열적 안정성이 매우 좋지 않아서, 진공 하에서 고온 증착 공정을 거칠 때, 물질이 변하는 등 단점을 갖고 있다. OLED에서 전력효율 = (π/전압) × 전류효율 이므로, 전력효율은 전압에 반비례하는데, OLED의 소비 전력이 낮으려면 전력 효율이 높아야한다. 실제 인광 발광 재료를 사용한 OLED는 형광 발광 재료를 사용한 OLED에 비해 전류 효율(cd/A)이 상당히 높으나, 인광 발광 재료의 호스트로 BAlq 나 CBP 등 종래의 재료를 사용할 경우, 형광재료를 사용한 OLED에 비해 구동 전압이 높아서 전력 효율(lm/w)면에서 큰 이점이 없었다. 또한, OLED 소자에서의 수명 측면에서도 결코 만족할만한 수준이 되질 못하여 더욱 안정되고, 더욱 성능이 뛰어난 호스트 재료의 개발이 요구되고 있다.However, existing materials have advantages in terms of luminescence properties, but the glass transition temperature is low and the thermal stability is not very good, and thus has a disadvantage such that the material changes when undergoing a high temperature deposition process under vacuum. Since power efficiency = (π / voltage) × current efficiency in OLEDs, power efficiency is inversely proportional to voltage. However, low power consumption of OLEDs requires high power efficiency. Actually, OLEDs using phosphorescent materials have significantly higher current efficiency (cd / A) than OLEDs using fluorescent materials.However, when a conventional material such as BAlq or CBP is used as a host of phosphorescent materials, OLEDs using fluorescent materials Compared with the higher driving voltage, there was no significant advantage in terms of power efficiency (lm / w). 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.
