  • Organic light-emitting devices have a structure in which an organic thin film is placed between two electrodes. When voltage is applied to an organic light emitting device with this structure, electrons and holes injected from two electrodes combine in the organic thin film to form a pair and then disappear, emitting light.
  • the organic thin film may be composed of a single layer or multiple layers, depending on need.
  • the material of the organic thin film may have a light-emitting function as needed.

본 발명은 헤테로 고리 화합물 및 이를 포함하는 유기 발광 소자에 관한 것이다.The present invention relates to heterocyclic compounds and organic light-emitting devices containing the same.
유기 발광 소자는 자체 발광형 표시 소자의 일종으로서, 시야각이 넓고, 콘트라스트가 우수할 뿐만 아니라 응답속도가 빠르다는 장점을 가지고 있다.Organic light emitting devices are a type of self-emitting display devices and have the advantages of a wide viewing angle, excellent contrast, and fast response speed.
유기 발광 소자는 2개의 전극 사이에 유기 박막을 배치시킨 구조를 가지고 있다. 이와 같은 구조의 유기 발광 소자에 전압이 인가되면, 2개의 전극으로부터 주입된 전자와 정공이 유기 박막에서 결합하여 쌍을 이룬 후 소멸하면서 빛을 발하게 된다. 상기 유기 박막은 필요에 따라 단층 또는 다층으로 구성될 수 있다.Organic light-emitting devices have a structure in which an organic thin film is placed between two electrodes. When voltage is applied to an organic light emitting device with this structure, electrons and holes injected from two electrodes combine in the organic thin film to form a pair and then disappear, emitting light. The organic thin film may be composed of a single layer or multiple layers, depending on need.
유기 박막의 재료는 필요에 따라 발광 기능을 가질 수 있다. 예컨대, 유기 박막 재료로는 그 자체가 단독으로 발광층을 구성할 수 있는 화합물이 사용될 수도 있고, 또는 호스트-도펀트계 발광층의 호스트 또는 도펀트 역할을 할 수 있는 화합물이 사용될 수도 있다. 그 외에도, 유기 박막의 재료로서, 정공 주입, 정공 수송, 전자 저지, 정공 저지, 전자 수송, 전자 주입 등의 역할을 수행할 수 있는 화합물이 사용될 수도 있다.The material of the organic thin film may have a light-emitting function as needed. For example, as an organic thin film material, a compound that can independently form a light-emitting layer may be used, or a compound that can act as a host or dopant of a host-dopant-based light-emitting layer may be used. In addition, as a material for the organic thin film, compounds that can perform roles such as hole injection, hole transport, electron blocking, hole blocking, electron transport, and electron injection may be used.
유기 발광 소자의 성능, 수명 또는 효율을 향상시키기 위하여, 유기 박막의 재료의 개발이 지속적으로 요구되고 있다.In order to improve the performance, lifespan, or efficiency of organic light-emitting devices, the development of organic thin film materials is continuously required.

마지막으로 전자 수송층 위에 리튬 플루오라이드(lithium fluoride: LiF)를 10Å 두께로 증착하여 전자 주입층을 형성한 후, 전자 주입층 위에 알루미늄(Al) 음극을 1,200Å의 두께로 증착하여 음극을 형성함으로써 유기 발광 소자를 제조하였다.Finally, lithium fluoride (LiF) was deposited to a thickness of 10Å on the electron transport layer to form an electron injection layer, and then an aluminum (Al) cathode was deposited to a thickness of 1,200Å on the electron injection layer to form the cathode, thereby forming an organic A light emitting device was manufactured.

(2) 유기 발광 소자의 구동 전압 및 발광 효율(2) Driving voltage and luminous efficiency of organic light-emitting devices
상기와 같이 제작된 유기 발광 소자에 대하여 맥사이언스사의 M7000으로 전계 발광(EL)특성을 측정하였으며, 그 측정 결과를 가지고 맥사이언스사에서 제조된 수명장비측정장비(M6000)를 통해 기준 휘도가 20,000 cd/m2 일 때, 초기 휘도 대비 95%가 되는 시간인 수명 T95 (단위: h, 시간)를 측정하였다.The electroluminescence (EL) characteristics of the organic light emitting device manufactured as described above were measured using McScience's M7000, and the standard luminance was measured to be 20,000 cd using the measurement results using a lifespan measurement equipment (M6000) manufactured by McScience. When /m 2 , the lifespan T 95 (unit: h, time), which is the time for 95% of the initial luminance, was measured.
본 발명에 따라 제조된 유기 발광 소자의 구동전압, 발광효율 및 수명을 측정한 결과는 하기 표 5와 같았다.The results of measuring the driving voltage, luminous efficiency, and lifespan of the organic light-emitting device manufactured according to the present invention are shown in Table 5 below.

상기 표 5의 결과로부터 알 수 있듯이, 본 발명의 화학식 1로 표시되는 화합물을 정공 수송층 재료로 이용한 유기 발광 소자(실시예 1 내지 58)는 비교예 1 내지 4의 화합물을 정공 수송층 재료로 이용한 유기 발광 소자에 비해 구동 전압이 낮고, 발광효율 및 수명이 현저히 개선되었다. As can be seen from the results in Table 5, the organic light-emitting devices (Examples 1 to 58) using the compound represented by Formula 1 of the present invention as the hole transport layer material were the organic light emitting devices using the compounds of Comparative Examples 1 to 4 as the hole transport layer material. Compared to light-emitting devices, the driving voltage is lower, and the luminous efficiency and lifespan are significantly improved.
비교예 2 내지 4에 사용된 M1 내지 M3의 화합물은 디메틸플루오레노벤조퓨란 타입의 5환 골격을 가지고 있는 점에서 본 발명의 화학식 1의 화합물과 유사하나, M1 및 M3의 화합물의 경우 디메틸플루오레노벤조퓨란의 4번 위치에 아릴아민 치환기가 도입되었고, 본 발명의 화합물은 4번 위치에 아릴아민 치환기가 도입되어 있지 않다는 점에서 차이가 있다. 상기 디메틸플루오레노벤조퓨란의 4번 위치에 아릴아민기가 도입이 되었을 경우, 다른 위치에 비해 정공이동도가 느려지는 단점이 있다. 본 발명의 화합물의 경우 상기 모핵의 4번 위치가 아닌 다른 위치에 아릴아민기가 도입됨으로써 정공이동도의 물성이 우수해져서 소자 특성이 우수해짐을 확인하였다.The compounds M1 to M3 used in Comparative Examples 2 to 4 are similar to the compounds of Formula 1 of the present invention in that they have a dimethylfluorenobenzofuran-type 5-ring skeleton, but in the case of the compounds M1 and M3, dimethylfluoreno An arylamine substituent is introduced at the 4th position of benzofuran, and the compound of the present invention is different in that an arylamine substituent is not introduced at the 4th position. When an arylamine group is introduced at position 4 of the dimethylfluorenobenzofuran, there is a disadvantage that hole mobility becomes slower compared to other positions. In the case of the compound of the present invention, it was confirmed that the arylamine group was introduced at a position other than the 4th position of the parent nucleus, thereby improving the physical properties of hole mobility and improving device characteristics.
비교예 3에 사용된 M2의 화합물의 경우 디메틸플루오레노벤조퓨란 타입의 5환 골격을 가지고 있는 점에서, 본 발명의 화학식 1의 화합물과 유사하나, 아릴아민기의 2치환 구조를 가지고 있다. 상기 디메틸플루오레노벤조퓨란 타입의 골격 구조에 디아릴아민기로 2치환 구조를 가지고 있을 경우, HOMO 준위가 높아지게 된다. 본 발명의 화학식 1의 화합물은 단일 아릴아민 치환기를 가짐으로써 HOMO 준위가 비교예 3에 사용된 M2의 화합물보다 낮다. HOMO 준위가 낮아짐으로써 정공수송층과 발광층 사이의 HOMO 준위 차이가 적어져 정공수송이 더 용이해지게 되고, 이러한 이유로 소자 특성이 우수해짐을 확인하였다.The compound M2 used in Comparative Example 3 is similar to the compound of Formula 1 of the present invention in that it has a dimethylfluorenobenzofuran-type 5-ring skeleton, but has a 2-substituted arylamine group structure. When the dimethylfluorenobenzofuran type skeletal structure has a 2-substituted diarylamine group, the HOMO level increases. The compound of Formula 1 of the present invention has a single arylamine substituent, so its HOMO level is lower than that of the compound M2 used in Comparative Example 3. As the HOMO level is lowered, the HOMO level difference between the hole transport layer and the light emitting layer is reduced, making hole transport easier, and for this reason, it was confirmed that the device characteristics are improved.
