Description

유기전기소자용 화합물, 이를 포함하는 유기전기소자 및 그 전자 장치Compound for organic electric device, organic electric device comprising same and electronic device thereof
본 발명은 오원자 헤테로 고리를 포함하는 화합물, 이를 이용한 유기전기소자 및 그 전자 장치에 관한 것이다.The present invention relates to a compound comprising a five-membered hetero ring, an organic electric element using 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 emitting phenomenon refers to a phenomenon of converting electrical energy into light energy using an organic material. An organic electric element using an organic light emitting phenomenon usually has a structure including an anode, a cathode, and an organic material layer therebetween. The organic layer is often made of a multi-layer structure composed of different materials in order to increase the efficiency and stability of the organic electrical device, for example, it may be made 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 전하 수송 재료, 예컨대 정공주입 재료, 정공수송 재료, 전자수송 재료, 전자주입 재료 등으로 분류될 수 있다. 그리고, 상기 발광 재료는 분자량에 따라 고분자형과 저분자형으로 분류될 수 있고, 발광 메커니즘에 따라 전자의 일중항 여기상태로부터 유래되는 형광 재료와 전자의 삼중항 여기상태로부터 유래되는 인광 재료로 분류될 수 있다. 또한, 발광 재료는 발광색에 따라 청색, 녹색, 적색 발광 재료와 보다 나은 천연색을 구현하기 위해 필요한 노란색 및 주황색 발광 재료로 구분될 수 있다.Materials used as the organic material layer in the organic electric element may be classified into light emitting materials and charge transport materials such as hole injection materials, hole transport materials, electron transport materials, electron injection materials and the like depending on their functions. The light emitting material may be classified into a polymer type and a low molecular type according to molecular weight, and may be classified into a fluorescent material derived from a singlet excited state of electrons and a phosphorescent material derived from a triplet excited state of electrons according to a light emitting mechanism. Can be. In addition, the light emitting material may be classified into blue, green, and red light emitting materials and yellow and orange light emitting materials required to achieve a better natural color according to the light emitting color.
특히, 유기전기소자의 우수한 수명 특성을 위해 정공 수송층 또는 완충층(buffer layer)으로 삽입되는 유기물질에 관해 여러 연구가 진행되고 있으며, 이를 위해 양극으로부터 유기층으로의 높은 정공 이동 특성을 부여하면서 증착 후 박막 형성시 균일도가 높고 결정화도가 낮은 정공 주입층 재료가 요구되고 있다.In particular, various studies have been conducted on organic materials inserted into a hole transporting layer or a buffer layer for excellent life characteristics of the organic electric device, and for this, a thin film after deposition while giving high hole transporting characteristics from the anode to the organic layer There is a need for a hole injection layer material having high uniformity and low crystallinity in forming.
유기전기소자의 수명단축의 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.Delays penetration of metal oxide into the organic layer from the anode electrode (ITO), which is one of the causes of the shortening of the life of the organic electric device, and stable properties for Joule heating generated when driving the device, that is, high glass transition temperature. There is a need for development of a hole injection layer material having In addition, the low glass transition temperature of the hole transport layer material has been reported to have a significant effect on the device life, depending on the characteristics of the uniformity of the surface of the thin film when driving the device. In addition, the deposition method is the mainstream in the formation of the OLED device, a situation that requires a material that can withstand a long time, that is, a material having a strong heat resistance characteristics.
한편, 발광 재료로서 하나의 물질만 사용하는 경우 분자간 상호 작용에 의하여 최대 발광 파장이 장파장으로 이동하고 색순도가 떨어지거나 발광 감쇄 효과로 소자의 효율이 감소되는 문제가 발생하므로, 색순도의 증가와 에너지 전이를 통한 발광 효율을 증가시키기 위하여 발광 재료로서 호스트/도판트계를 사용할 수 있다. 그 원리는 발광층을 형성하는 호스트보다 에너지 대역 간극이 작은 도판트를 발광층에 소량 혼합하면, 발광층에서 발생한 엑시톤이 도판트로 수송되어 효율이 높은 빛을 내는 것이다. 이때 호스트의 파장이 도판트의 파장대로 이동하므로, 이용하는 도판트의 종류에 따라 원하는 파장의 빛을 얻을 수 있다.On the other hand, when only one material is used as the light emitting material, the maximum light emission wavelength is shifted to the long wavelength due to the intermolecular interaction, and the color purity decreases or the efficiency of the device decreases due to the light emission attenuation effect. In order to increase the light emitting efficiency through the light emitting material, a host / dopant system may be used. The principle is that when a small amount of dopant having an energy band gap smaller than that of the host forming the light emitting layer is mixed in the light emitting layer, excitons generated in the light emitting layer are transported to the dopant, thereby producing high efficiency light. At this time, since the wavelength of the host is shifted to the wavelength of the dopant, light having a desired wavelength can be obtained according to the type of dopant to be used.
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 fully exhibit the excellent characteristics of the above-described organic electroluminescent device, a material constituting the organic material layer in the device, such as a hole injection material, a hole transport material, a light emitting material, an electron transport material, an electron injection material, etc., is supported by a stable and efficient material. Although this should be preceded, the development of a stable and efficient organic material layer for an organic electric device has not been made sufficiently, and therefore, the development of new materials is still required.
본 발명은 소자의 높은 발광효율, 낮은 구동전압, 색순도, 및 수명을 향상시킬 수 있는 오원자 헤테로 고리를 포함하는 화합물 및 이를 이용한 유기전기소자, 그 전자 장치를 제공하는 것을 목적으로 한다.An object of the present invention is to provide a compound containing an five-membered hetero ring capable of improving the luminous efficiency, low driving voltage, color purity, and lifetime of the device, an organic electric device using the same, and an electronic device thereof.

도 1을 참조하면, 본 발명에 따른 유기전기소자(100)는 기판(110) 상에 형성된 제 1전극(120), 제 2전극(180) 및 제 1전극(110)과 제 2전극(180) 사이에 화학식 1로 표시되는 화합물을 포함하는 유기물층을 구비한다. 이때, 제 1전극(120)은 애노드(양극)이고, 제 2전극(180)은 캐소드(음극)일 수 있으며, 인버트형의 경우에는 제 1전극이 캐소드이고 제 2전극이 애노드일 수 있다.Referring to FIG. 1, the organicelectric device 100 according to the present invention includes a first electrode 120, a second electrode 180, a first electrode 110, and a second electrode 180 formed on a substrate 110. An organic material layer containing a compound represented by the formula (1) between) is provided. In this case, the first electrode 120 may be an anode (anode), the second electrode 180 may be a cathode (cathode), and in the case of an inverted type, the first electrode may be a cathode and the second electrode may be an anode.
유기물층은 제 1전극(120) 상에 순차적으로 정공주입층(130), 정공수송층(140), 발광층(150), 전자수송층(160) 및 전자주입층(170)을 포함할 수 있다. 이때, 발광층(150)을 제외한 나머지 층들이 형성되지 않을 수 있다. 정공저지층, 전자저지층, 발광보조층(151), 버퍼층(141) 등을 더 포함할 수도 있고, 전자수송층(160) 등이 정공저지층의 역할을 할 수도 있을 것이다.The organic layer may include a hole injection layer 130, a hole transport layer 140, a light emitting layer 150, an electron transport layer 160, and an electron injection layer 170 on the first electrode 120 in sequence. At this time, the remaining layers except for the light emitting layer 150 may not be formed. The hole blocking layer, the electron blocking layer, the light emitting auxiliary layer 151, the buffer layer 141 may be further included, and the electron transport layer 160 may serve as the hole blocking layer.
또한, 미도시하였지만, 본 발명에 따른 유기전기소자는 제 1전극과 제 2전극 중 적어도 일면 중 상기 유기물층과 반대되는 일면에 형성된 보호층을 더 포함할 수 있다.In addition, although not shown, the organic electronic device according to the present invention may further include a protective layer formed on one surface of the first electrode and the second electrode opposite to the organic material layer.

한편, 동일한 코어일지라도 어느 위치에 어느 치환기를 결합시키냐에 따라 밴드갭(band gap), 전기적 특성, 계면 특성 등이 달라질 수 있으므로, 코어의 선택 및 이에 결합된 서브(sub)-치환체의 조합도 아주 중요하며, 특히 각 유기물층 간의 에너지 level 및 T1 값, 물질의 고유특성(mobility, 계면특성 등) 등이 최적의 조합을 이루었을 때 긴 수명과 높은 효율을 동시에 달성할 수 있다.Meanwhile, even in the same core, band gaps, electrical characteristics, and interface characteristics may vary depending on which substituents are bonded at which positions. Therefore, the selection of cores and the combination of sub-substituents bound thereto are also very significant. Importantly, long life and high efficiency can be achieved at the same time when an optimal combination of energy level and T1 value and intrinsic properties (mobility, interfacial properties, etc.) of each organic material layer is achieved.
따라서, 본 발명에서는 화학식 1로 표시되는 화합물을 사용하여 발광층을 형성함으로써 각 유기물층 간의 에너지 레벨(level) 및 T1 값, 물질의 고유특성(mobility, 계면특성 등) 등을 최적화하여 유기전기소자의 수명 및 효율을 동시에 향상시킬 수 있다.Therefore, in the present invention, the light emitting layer is formed using the compound represented by Chemical Formula 1 to optimize the energy level and T1 value between each organic material layer, the intrinsic properties (mobility, interfacial properties, etc.) of the organic layers, and thus the lifetime of the organic electric device. And efficiency can be improved at the same time.

For example, the anode 120 is formed by depositing a metal or a conductive metal oxide or an alloy thereof on a substrate, and the hole injection layer 130, the hole transport layer 140, the light emitting layer 150, and the electron transport layer are formed thereon. After forming the organic material layer including the 160 and the electron injection layer 170, it can be prepared by depositing a material that can be used as the cathode 180 thereon.
또한, 유기물층은 다양한 고분자 소재를 사용하여 증착법이 아닌 용액 공정 또는 솔벤트 프로세스(solvent process), 예컨대 스핀 코팅, 딥 코팅, 닥터 블레이딩, 스크린 프린팅, 잉크젯 프린팅 또는 열 전사법 등의 방법에 의하여 더 적은 수의 층으로 제조할 수 있다. 본 발명에 따른 유기물층은 다양한 방법으로 형성될 수 있으므로, 그 형성방법에 의해 본 발명의 권리범위가 제한되는 것은 아니다.In addition, the organic layer may be prepared by using a variety of polymer materials, but not by a deposition process or a solvent process such as spin coating, dip coating, doctor blading, screen printing, inkjet printing or thermal transfer.

상기 화학식 1에서,In Chemical Formula 1,
R1 내지 R10은 i) 서로 독립적으로, 수소, 중수소, 할로겐, C6~C60의 아릴기, 플루오렌일기, C3~C60의 지방족고리와 C6~C60의 방향족고리의 융합고리기, O, N, S, Si 및 P 중 적어도 하나의 헤테로원자를 포함하는 C2~C60의 헤테로 고리기, -L-N(R’)(R”), C1~C50의 알킬기, C2~C20의 알켄일기, C1~C30의 알콕시기 및 C6~C30의 아릴옥시기로 이루어진 군에서 선택되거나, 또는 ii) 이웃한 기끼리 서로 결합하여 적어도 하나의 고리를 형성한다(이때, 고리를 형성하지 않는 기는 i)에서 정의된 것과 같다).R1 to R10 is i) independent of each other, hydrogen, deuterium, halogen, C6 ~ aryl group of C60, a fluorene group, a fused aromatic ring of C3 ~ C60 of aliphatic rings and C6 ~ C60 C2 -C60 heterocyclic group including a ring group, O, N, S, Si and P heteroatoms, -LN (R ') (R "), C1 ~ C50 Alkyl group, Selected from the group consisting of a C2 to C20 alkenyl group, a C1 to C30 alkoxy group and a C6 to C30 aryloxy group, or ii) adjacent groups combine with each other to form at least one ring Where the groups which do not form a ring are as defined in i).
단, R5와 R6이 서로 결합하여 고리를 형성하는 경우에 한해 R1~R4와 R7~R10 이 동시에 모두 수소일 수 있으며, R5와 R6이 서로 결합하여 고리를 형성하지 않는 경우에는 R1~R4 중 적어도 하나와 R7~R10 중 적어도 하나는 수소가 아니어야 한다.However, only when R5 and R6 are bonded to each other to form a ring, R1 to R4 and R7 to R10 may be all hydrogen at the same time, and R5 and R6 are not bonded to each other to form a ring. Otherwise at least one of R1 to R4 and at least one of R7 to R10 should not be hydrogen.
즉, R1~R4와 R7~R10 각각이 수소가 될 수 있지만, 이들이 모두 동시에 수소일 수 있는 경우는 R5와 R6이 서로 결합하여 고리를 형성하는 경우에 한한다. 물론, R5와 R6이 서로 고리를 형성할 경우, R1~R4 및 R7~R10 중 적어도 하나가 수소를 제외하고 상기 정의된 치환기일 수 있다. 단, 이경우에도(R5와 R6이 서로 결합하여 고리를 형성하지 않는 경우) R1~R4 중 적어도 하나가 수소 이외의 치환기이어야 함과 동시에 R7~R10중 적어도 하나가(하나 이상이) 수소 이외의 치환기이어야 한다. 따라서, 가 고리를 형성하지 않는데 R1~R4 가 모두 수소이거나/수소이고 R7~R10가 모두 수소인 경우는 제외한다.That is, ROne~ R4And R7~ R10 Each can be hydrogen, but if they can all be hydrogen at the same time,5And R6Only when these bond with each other to form a ring. Of course, R5And R6When they form a ring with each other, ROne~ R4 And R7~ R10 At least one of may be a substituent as defined above except for hydrogen. However, even in this case (R5And R6R does not combine with each other to form a ring) ROne~ R4 At least one of R must be a substituent other than hydrogen and R7~ R10                At least one of (at least one) must be a substituent other than hydrogen. Thus, does not form a ring ROne~ R4 Are all hydrogen / hydrogen and R7~ R10Except when are all hydrogen.
또한, ii)에서, R1과 R10 중 이웃한 기끼리 서로 결합하여 적어도 하나의 고리를 형성한다 함은, R1과 R2끼리, R2와 R3끼리, R3와 R4끼리, R5와 R6끼리, R7과 R8끼리, R8과 R9끼리 및/또는 R9와 R10끼리 서로 결합하여 고리를 형성하는 것을 말한다. 이때, 이웃한 기끼리 서로 결합하여 고리를 형성한다는 자체가 중요하므로, 이들이 어떤 치환기이고 어떤 반응을 통해 고리가 형성되는지에 의해 본 발명의 권리범위가 제한되지는 않는다.In addition, in ii), adjacent groups of R1 and R10 combine with each other to form at least one ring, R1 and R2 , R2 and R3 , R3 and R4 , R5 and R6 , R7 and R8 , R8 and R9, and / or R9 and R10 are bonded to each other to form a ring. At this time, since it is important that the adjacent groups are bonded to each other to form a ring, the scope of the present invention is not limited by what substituents and by what reaction the ring is formed.
R1과 R10 중 이웃한 기끼리 서로 결합하여 형성된 고리는 단환 또는 다환의 방향족고리 또는 헤테로 원자를 적어도 하나 포함하는 헤테로고리일 수 있을 뿐만 아니라 방향족고리와 지방족 고리가 융합된 형태일 수도 있다. 예시적으로, R1과 R10 중 이웃한 기끼리 서로 결합하여 벤젠, 나프탈렌, 페난트렌 등과 같은 방향족고리를 형성할 수 있는데, 이때 형성되는 방향족고리의 핵탄소수는 6 내지 60인 것이 바람직하다. 예컨대, R7과 R8이 서로 결합하여 벤젠고리를 형성하고, R9와 R10이 서로 결합하여 벤젠고리를 형성하면 이들이 결합된 모핵의 벤젠링과 함께 페난트렌 형태가 형성될 수 있을 것이다.The ring formed by bonding of adjacent groups of R1 and R10 to each other may be a monocyclic or polycyclic aromatic ring or a heterocyclic ring containing at least one heteroatom, or a fused aromatic ring with an aliphatic ring. For example, adjacent groups of R1 and R10 may be bonded to each other to form an aromatic ring such as benzene, naphthalene, phenanthrene, and the like. For example, when R7 and R8 are bonded to each other to form a benzene ring, and R9 and R10 are bonded to each other to form a benzene ring, a phenanthrene form may be formed together with the benzene ring of the mother nucleus to which they are bonded.
또한, R1과 R10이 서로 결합하여 싸이오펜, 퓨란, 피리딘, 인돌, 퀴놀린 등과 같은 헤테로고리를 형성할 수 있는데, 이때 핵탄소수는 2 내지 60일 수 있다. 또한, 다환고리인 경우 서로 융합된(fused) 형태일 수도 있고 복수개의 환이 서로 융합되지 않은 형태일 수도 있으며, 융합된 형태와 비융합된 형태가 혼합된 환일 수도 있다.In addition, R1 and R10 may be bonded to each other to form a hetero ring such as thiophene, furan, pyridine, indole, quinoline, etc., wherein the carbon number may be 2 to 60. In the case of a polycyclic ring, the ring may be fused to each other, a plurality of rings may not be fused to each other, or a ring in which the fused and non-fused forms are mixed.
