Description

신규한 발광 화합물 및 이를 포함하는 유기발광소자 {NOVEL ELECTROLUMINESCENT COMPOUND AND ORGANIC ELECTROLUMINESCENT DEVICE COMPRISING SAME}TECHNICAL FIELD [0001] The present invention relates to a novel luminescent compound, and an organic luminescent device including the luminescent compound.

본 발명은 신규한 발광 화합물 및 이를 포함하는 유기발광소자에 관한 것이다.
The present invention relates to a novel light emitting compound and an organic light emitting device including the same.

최근, 자체 발광형으로 저전압 구동이 가능한 유기발광소자는, 평판 표시소자의 주류인 액정디스플레이(LCD, liquid crystal display)에 비해, 시야각, 대조비 등이 우수하고 백라이트가 불필요하여 경량 및 박형이 가능하며 소비전력 측면에서도 유리하고 색 재현 범위가 넓어, 차세대 표시소자로서 주목을 받고 있다.In recent years, an organic light emitting device capable of being driven by a low voltage in a self-luminous mode has a better viewing angle and contrast ratio than a liquid crystal display (LCD), which is a mainstream of a flat panel display device, It has been attracting attention as a next generation display device because it is advantageous in terms of power consumption and has a wide color reproduction range.

유기발광소자에서 유기물 층으로 사용되는 재료는 크게 기능에 따라, 발광 재료, 정공주입 재료, 정공수송 재료, 전자수송 재료, 전자주입 재료 등으로 분류될 수 있다. 상기 발광 재료는 분자량에 따라 고분자과 저분자로 분류될 수 있고, 발광 메커니즘에 따라 전자의 일중항 여기상태로부터 유래되는 형광 재료와 전자의 삼중항 여기상태로부터 유래되는 인광 재료로 분류될 수 있으며, 발광 재료는 발광 색에 따라 청색, 녹색, 적색 발광 재료와 보다 나은 천연색을 구현하기 위해 필요한 노란색 및 주황색 발광 재료로 구분될 수 있다. 또한, 색순도의 증가와 에너지 전이를 통한 발광 효율을 증가시키기 위하여, 발광 물질로서 호스트/도판트 계를 사용할 수 있다. 그 원리는 발광층을 주로 구성하는 호스트보다 에너지 대역 간극이 작고 발광 효율이 우수한 도판트를 발광층에 소량 혼합하면, 호스트에서 발생한 엑시톤이 도판트로 수송되어 효율이 높은 빛을 내는 것이다. 이때 호스트의 파장이 도판트의 파장대로 이동하므로, 이용하는 도판트와 호스트의 종류에 따라 원하는 파장의 빛을 얻을 수 있다. A material used as an organic material layer in an organic light emitting device can be classified into a light emitting material, a hole injecting material, a hole transporting material, an electron transporting material, and an electron injecting material depending largely on functions. The light emitting material may be classified into a polymer and a low molecular weight depending on the molecular weight, and may be classified into a fluorescent material derived from singlet excitation state of electrons and a phosphorescent material derived from the triplet excited state of electrons according to an emission mechanism, Can be classified into blue, green and red light emitting materials and yellow and orange light emitting materials necessary for realizing a better natural color depending on the emission color. Further, in order to increase the color purity and to increase the luminous efficiency through energy transfer, a host / dopant system can be used as a luminescent material. The principle is that when a small amount of dopant having a smaller energy band gap and a higher luminous efficiency than a host mainly constituting the light emitting layer is mixed with the light emitting layer in a small amount, the excitons generated in the host are transported to the dopant to emit light with high efficiency. At this time, since the wavelength of the host is shifted to the wavelength of the dopant, the light of the desired wavelength can be obtained according to the type of the dopant and the host.

현재까지 이러한 유기발광소자에 사용되는 물질로서 다양한 화합물들이 알려져 있으나, 이제까지 알려진 물질을 이용한 유기발광소자의 경우 높은 구동전압, 낮은 효율 및 짧은 수명으로 인해 실용화하는 데에 많은 어려움이 있었다. 따라서, 우수한 특성을 갖는 물질을 이용하여 저전압 구동, 고휘도 및 장수명을 갖는 유기발광소자를 개발하려는 노력이 지속되어 왔다.
Various compounds have been known as materials used in such organic light emitting devices. However, organic light emitting devices using known materials have been difficult to put to practical use due to high driving voltage, low efficiency, and short lifetime. Accordingly, efforts have been made to develop an organic light emitting device having low voltage driving, high luminance, and long life using a material having excellent characteristics.

상기와 같은 문제점을 해결하기 위해, 본 발명은 전하전달 특성이 우수하고, 동시에 높은 삼중항 에너지 및 높은 Tg를 가져, 유기발광소자에 적용시 낮은 구동전압, 고효율, 저소비전력, 장수명을 가지게 할 수 있는 신규한 발광 화합물을 제공하는 것을 목적으로 한다.
In order to solve the above-mentioned problems, the present invention has an excellent charge-transporting property, a high triplet energy and a high Tg, and can provide low driving voltage, high efficiency, low power consumption and long life And to provide a novel luminescent compound having such a structure.

본 발명은 또한 상기 화합물을 포함하여 낮은 구동전압, 고효율, 저소비전력, 장수명 구현이 가능한 유기발광소자를 제공하는 것을 목적으로 한다.
It is another object of the present invention to provide an organic light emitting device including the above compound capable of realizing low driving voltage, high efficiency, low power consumption, and long life.

상기 목적을 달성하기 위해 본 발명은 하기 화학식 1로 표시되는 발광 화합물을 제공한다:In order to accomplish the above object, the present invention provides a luminescent compound represented by the following Formula 1:

At this time, the compound of the present invention may be used alone or in combination with a known organic light emitting compound.

또한 본 발명의 유기발광소자는 상기 화학식 1로 표시되는 화합물을 포함하는 1층 이상의 유기물층을 포함하는 바, 상기 유기발광소자의 제조방법을 설명하면 다음과 같다.In addition, the organic light emitting device of the present invention includes one or more organic layers including the compound represented by Formula 1, and the method of manufacturing the organic light emitting device will now be described.

상기 유기발광소자는 애노드(anode)와 캐소드(cathod) 사이에 정공주입층(HIL), 정공수송층(HTL), 발광층(EML), 전자수송층(ETL), 전자주입층(EIL) 등의 유기물층을 1 개 이상 포함할 수 있다.The organic light emitting device includes an organic layer such as a hole injection layer (HIL), a hole transport layer (HTL), a light emitting layer (EML), an electron transport layer (ETL), and an electron injection layer (EIL) between an anode and a cathode One or more can be included.

먼저, 기판 상부에 높은 일함수를 갖는 애노드 전극용 물질을 증착시켜 애노드를 형성한다. 이때, 상기 기판은 통상의 유기발광소자에서 사용되는 기판을 사용할 수 있으며, 특히 기계적 강도, 열적 안정성, 투명성, 표면평활성, 취급용이성, 및 방수성이 우수한 유리 기판 또는 투명 플라스틱 기판을 사용하는 것이 좋다. 또한, 애노드 전극용 물질로는 투명하고 전도성이 우수한 산화인듐주석(ITO), 산화인듐아연(IZO), 산화주석(SnO2), 산화아연(ZnO) 등을 사용할 수 있다. 상기 애노드 전극용 물질은 통상의 애노드 형성방법에 의해 증착할 수 있으며, 구체적으로 증착법 또는 스퍼터링법에 의해 증착할 수 있다.First, an anode electrode material having a high work function is deposited on the substrate to form an anode. At this time, the substrate can be a substrate used in conventional organic light emitting devices, and it is particularly preferable to use a glass substrate or a transparent plastic substrate having excellent mechanical strength, thermal stability, transparency, surface smoothness, ease of handling, and waterproofness. As the material for the anode electrode, indium tin oxide (ITO), indium zinc oxide (IZO), tin oxide (SnO 2 ), zinc oxide (ZnO) and the like which are transparent and excellent in conductivity can be used. The anode electrode material can be deposited by a conventional anode formation method, and specifically, it can be deposited by a deposition method or a sputtering method.

그 다음, 상기 애노드 전극 상부에 정공주입층 물질을 진공증착법, 스핀코팅법, 캐스트법, LB(Langmuir-Blodgett)법 등과 같은 방법에 의해 형성할 수 있지만, 균일한 막질을 얻기 쉽고, 또한 핀정공이 발생하기 어렵다는 등의 점에서 진공증착법에 의해 형성하는 것이 바람직하다. 상기 진공증착법에 의해 정공주입층을 형성하는 경우 그 증착조건은 정공주입층의 재료로서 사용하는 화합물, 목적하는 정공주입층의 구조 및 열적특성 등에 따라 다르지만, 일반적으로 50-500 ℃의 증착온도, 10-8 내지 10-3 torr의 진공도, 0.01 내지 100 Å/sec의 증착속도, 10 Å 내지 5 ㎛의 층 두께 범위에서 적절히 선택하는 것이 바람직하다.Next, a hole injection layer material may be formed on the anode electrode by a method such as a vacuum deposition method, a spin coating method, a casting method, or an LB (Langmuir-Blodgett) method, but it is easy to obtain a uniform film quality, It is preferable to form it by a vacuum evaporation method. When the hole injection layer is formed by the vacuum deposition method, the deposition conditions vary depending on the compound used as the material of the hole injection layer, the structure and thermal properties of the desired hole injection layer, and the like. In general, the deposition temperature is 50-500 [ A vacuum degree of 10 -8 to 10 -3 torr, a deposition rate of 0.01 to 100 Å / sec, and a layer thickness range of 10 Å to 5 탆.

상기 정공주입층 물질은 특별히 제한되지 않으며, 미국특허 제4,356,429호에 개시된 구리 프탈로시아닌 등의 프탈로시아닌 화합물 또는 스타버스트형 아민 유도체류인 TCTA(4,4',4"-트리(N-카바졸릴)트리페닐아민), m-MTDATA(4,4',4"-트리스(3-메틸페닐아미노)트리페닐아민), m-MTDAPB(4,4',4"-트리스(3-메틸페닐아미노)페녹시벤젠), HI-406(N1,N1'-(비페닐-4,4'-디일)비스(N1-(나프탈렌-1-일)-N4,N4-디페닐벤젠-1,4-디아민) 등을 정공주입층 물질로 사용할 수 있다.The hole injection layer material is not particularly limited and may be a phthalocyanine compound such as copper phthalocyanine disclosed in U.S. Patent No. 4,356,429 or a star burst type amine derivative TCTA (4,4 ', 4 "-tri (N-carbazolyl) tri (4,4 ', 4 "-tris (3-methylphenylamino) triphenylamine), m-MTDAPB ), HI-406 (N 1 , N 1 '- ( biphenyl-4,4'-diyl) bis (N 1 - (naphthalen-1-yl) -N 4, N 4 - benzene-1,4-diphenyl -Diamine) can be used as a hole injection layer material.

다음으로 상기 정공주입층 상부에 정공수송층 물질을 진공증착법, 스핀코팅법, 캐스트법, LB법 등과 같은 방법에 의해 형성할 수 있지만, 균일한 막질을 얻기 쉽고, 핀정공이 발생하기 어렵다는 점에서 진공증착법에 의해 형성하는 것이 바람직하다. 상기 진공증착법에 의해 정공수송층을 형성하는 경우 그 증착조건은 사용하는 화합물에 따라 다르지만 일반적으로 정공주입층의 형성과 거의 동일한 조건 범위에서 선택하는 것이 좋다.Next, a hole transporting layer material may be formed on the hole injecting layer by a method such as a vacuum deposition method, a spin coating method, a casting method, an LB method, etc. However, since a uniform film quality can be easily obtained, It is preferably formed by a vapor deposition method. When the hole transporting layer is formed by the vacuum deposition method, the deposition conditions vary depending on the compound used, but it is generally preferable to select the conditions within the substantially same range as the formation of the hole injection layer.

또한, 상기 정공수송층 물질은 특별히 제한되지는 않으며, 정공수송층에 사용되고 있는 통상의 공지 물질 중에서 임의로 선택하여 사용할 수 있다. 구체적으로, 상기 정공수송층 물질은 N-페닐카바졸, 폴리비닐카바졸 등의 카바졸 유도체, N,N'-비스(3-메틸페닐)-N,N'-디페닐-[1,1-비페닐]-4,4'-디아민(TPD), N.N'-디(나프탈렌-1-일)-N,N'-디페닐 벤지딘(α-NPD) 등의 방향족 축합환을 가지는 통상의 아민 유도체 등이 사용될 수 있다.In addition, the hole transport layer material is not particularly limited, and may be selected from any conventionally known materials used in the hole transport layer. Specifically, the hole transport layer material may be a carbazole derivative such as N-phenylcarbazole or polyvinylcarbazole, a carbazole derivative such as N, N'-bis (3-methylphenyl) -N, N'- Phenyl) -4,4'-diamine (TPD), and N, N'-di (naphthalene-1-yl) -N, N'-diphenylbenzidine Derivatives and the like can be used.

그 후, 상기 정공수송층 상부에 발광층 물질을 진공증착법, 스핀코팅법, 캐스트법, LB법 등과 같은 방법에 의해 형성할 수 있지만, 균일한 막질을 얻기 쉽고, 핀정공이 발생하기 어렵다는 점에서 진공증착법에 의해 형성하는 것이 바람직하다. 상기 진공증착법에 의해 발광층을 형성하는 경우 그 증착조건은 사용하는 화합물에 따라 다르지만 일반적으로 정공주입층의 형성과 거의 동일한 조건 범위에서 선택하는 것이 좋다. 또한, 상기 발광층 재료는 본 발명의 화학식 1로 표시되는 화합물을 호스트 또는 도펀트로 사용할 수 있다.Then, the light emitting layer material may be formed on the hole transporting layer by a method such as a vacuum deposition method, a spin coating method, a casting method, an LB method, etc. However, from the viewpoint of obtaining a uniform film quality and difficulty in producing pin holes, As shown in Fig. When the light emitting layer is formed by the vacuum vapor deposition method, the deposition conditions vary depending on the compound used, but it is generally preferable to select the conditions within the substantially same range as the formation of the hole injection layer. The light emitting layer material may use the compound represented by the formula (1) of the present invention as a host or a dopant.

상기 화학식 1로 표시되는 화합물을 발광 호스트로 사용하는 경우, 인광 또는 형광 도펀트를 함께 사용하여 발광층을 형성할 수 있다. 이때, 형광 도펀트로는 이데미츠사(Idemitsu사)에서 구입 가능한 IDE102 또는 IDE105, 또는 BD142(N6,N12-비스(3,4-디메틸페닐)-N6,N12-디메시틸크리센-6,12-디아민)를 사용할 수 있으며, 인광 도펀트로는 녹색 인광 도펀트 Ir(ppy)3(트리스(2-페닐피리딘) 이리듐), 청색 인광 도펀트인 F2Irpic(이리듐(Ⅲ) 비스[4,6-다이플루오로페닐)-피리디나토-N,C2'] 피콜린산염), UDC사의 적색 인광 도펀트 RD61 등이 공동 진공증착(도핑)될 수 있다. 도펀트의 도핑농도는 특별히 제한되지 않으나, 호스트 100 중량부 대비 도펀트가 0.01 내지 15 중량부로 도핑되는 것이 바람직하다. 만약 도펀트의 함량이 0.01 중량부 미만일 경우에는 도펀트량이 충분치 못하여 발색이 제대로 이루어지지 않는다는 문제점이 있으며, 15 중량부를 초과할 경우에는 농도 소광 현상으로 인해 효율이 급격히 감소된다는 문제점이 있다.When the compound represented by Formula 1 is used as a light emitting host, a phosphorescent or fluorescent dopant may be used together to form a light emitting layer. At this time, the fluorescent dopant to the possible purchase from Idemitsu Co. (Idemitsu Corporation) IDE102 or IDE105, or BD142 (N 6, N 12-bis (3,4-dimethylphenyl) -N 6, N 12 - D-mesityl chrysene - as may be used to 6,12- diamine), the phosphorescent dopant is a green phosphorescent dopant Ir (ppy) 3 (tris (2-phenylpyridine) iridium), a blue phosphorescent dopant F2Irpic (iridium (ⅲ) bis [4,6- Pyridino-N, C2 '] picolinate), UDC's red phosphorescent dopant RD61, and the like can be vacuum vacuum deposited (doped). The doping concentration of the dopant is not particularly limited, but is preferably doped with 0.01 to 15 parts by weight of the dopant relative to 100 parts by weight of the host. If the content of the dopant is less than 0.01 part by weight, the amount of the dopant is not sufficient and color development is not properly performed. If the amount is more than 15 parts by weight, the efficiency is drastically reduced due to the concentration quenching phenomenon.

또한, 발광층에 인광 도펀트와 함께 사용할 경우에는 삼중항 여기자 또는 정공이 전자수송층으로 확산되는 현상을 방지하기 위하여 정공억제재료(HBL)를 추가로 진공증착법 또는 스핀코팅법에 의해 적층시키는 것이 바람직하다. 이때 사용할 수 있는 정공억제물질은 특별히 제한되지는 않으나, 정공억제재료로 사용되고 있는 공지의 것에서 임의의 것을 선택해서 이용할 수 있다. 예를 들면, 옥사디아졸 유도체나 트리아졸 유도체, 페난트롤린 유도체, 또는 일본특개평 11-329734(A1)에 기재되어 있는 정공억제재료 등을 들 수 있으며, 대표적으로 Balq(비스(8-하이드록시-2-메틸퀴놀리놀나토)-알루미늄 비페녹사이드), 페난트롤린(phenanthrolines)계 화합물(예: UDC사 BCP(바쏘쿠프로인)) 등을 사용할 수 있다.When the phosphorescent dopant is used together with the phosphorescent dopant, it is preferable to further laminate the hole blocking material (HBL) by a vacuum evaporation method or a spin coating method in order to prevent the triplet exciton or hole from diffusing into the electron transporting layer. The hole blocking material that can be used at this time is not particularly limited, but any known hole blocking material may be used. For example, an oxadiazole derivative, a triazole derivative, a phenanthroline derivative, or a hole blocking material described in Japanese Patent Laid-Open Publication No. 11-329734 (A1) can be exemplified. Typically, Balq (bis Phenanthrolines based compounds such as UDC company BCP (bassocouroin), and the like can be used.

상기와 같이 형성된 발광층 상부에는 전자수송층이 형성되는데, 이때 상기 전자수송층은 진공증착법, 스핀코팅법, 캐스트법 등의 방법으로 형성되며, 특히 진공증착법에 의해 형성하는 것이 바람직하다.An electron transport layer is formed on the light emitting layer formed as described above. The electron transport layer is formed by a vacuum deposition method, a spin coating method, a casting method, or the like, and is preferably formed by a vacuum deposition method.

상기 전자수송층 재료는 전자주입전극으로부터 주입된 전자를 안정하게 수송하는 기능을 하는 것으로서 그 종류가 특별히 제한되지는 않으며, 예를 들어 퀴놀린 유도체, 특히 트리스(8-퀴놀리놀라토)알루미늄(Alq3), 또는 ET4(6,6'-(3,4-디메시틸-1,1-디메틸-1H-실올-2,5-디일)디-2,2'-비피리딘)을 사용할 수 있다. 또한, 전자수송층 상부에 캐소드로부터 전자의 주입을 용이하게 하는 기능을 가지는 물질인 전자주입층(EIL)이 적층될 수 있으며, 전자주입층 물질로는 LiF, NaCl, CsF, Li2O, BaO 등의 물질을 이용할 수 있다.The electron transport layer material serves to stably transport electrons injected from the electron injection electrode. The material is not particularly limited, and examples thereof include quinoline derivatives, especially tris (8-quinolinolato) aluminum (Alq 3 ), Or ET4 (6,6 '- (3,4-dimemethyl-1,1-dimethyl-1H-silanol-2,5-diyl) di-2,2'-bipyridine). In addition, an electron injection layer (EIL), which is a material having a function of facilitating the injection of electrons from the cathode, may be laminated on the electron transport layer. Examples of the electron injection layer material include LiF, NaCl, CsF, Li 2 O, BaO Can be used.

또한, 상기 전자수송층의 증착조건은 사용하는 화합물에 따라 다르지만, 일반적으로 정공주입층의 형성과 거의 동일한 조건 범위에서 선택하는 것이 좋다.The deposition conditions of the electron transporting layer depend on the compound used, but it is generally preferable to select the conditions within the same range as the formation of the hole injection layer.

그 뒤, 상기 전자수송층 상부에 전자주입층 물질을 형성할 수 있으며, 이때 상기 전자수송층은 통상의 전자주입층 물질을 진공증착법, 스핀코팅법, 캐스트법 등의 방법으로 형성되며, 특히 진공증착법에 의해 형성하는 것이 바람직하다.Thereafter, an electron injection layer material may be formed on the electron transport layer, and the electron transport layer may be formed by a vacuum deposition method, a spin coating method, a casting method, or the like, .

마지막으로 전자주입층 상부에 캐소드 형성용 금속을 진공증착법이나 스퍼터링법 등의 방법에 의해 형성하고 캐소드로 사용한다. 여기서 캐소드 형성용 금속으로는 낮은 일함수를 가지는 금속, 합금, 전기전도성 화합물, 및 이들의 혼합물을 사용할 수 있다. 구체적인 예로는 리튬(Li), 마그네슘(Mg), 알루미늄(Al), 알루미늄-리튬(Al-Li), 칼슘(Ca), 마그네슘-인듐(Mg-In), 마그네슘-은(Mg-Ag) 등이 있다. 또한, 전면 발광소자를 얻기 위하여 ITO, IZO를 사용한 투과형 캐소드를 사용할 수도 있다.Finally, a metal for forming a cathode is formed on the electron injection layer by a vacuum evaporation method, a sputtering method, or the like, and used as a cathode. As the metal for cathode formation, a metal, an alloy, an electrically conductive compound having a low work function, and a mixture thereof can be used. Specific examples thereof include Li, Mg, Al, Al-Li, Ca, Mg-In, Mg-Ag, . Also, a transmissive cathode using ITO or IZO may be used to obtain a front light emitting element.
