본 발명은 신규한 유기발광소자용 화합물 및 이를 포함하는 유기막 재료용 코팅액 조성물에 관한 것으로, 보다 상세하게는 용액공정이 가능하며, 유기발광소자에 사용될 경우에 개선된 소자특성을 구현할 수 있는 유기발광소자용 화합물 및 이를 포함하는 유기막 재료용 코팅액 조성물에 관한 것이다.The present invention relates to a novel organic light emitting device compound and a coating liquid composition for an organic film material comprising the same, more specifically, a solution process is possible, and when used in an organic light emitting device, an organic device capable of realizing improved device characteristics It relates to a compound for a light emitting device and a coating liquid composition for an organic film material containing the same.

유기 발광 현상이란, 유기 물질을 이용하여 전기에너지를 빛 에너지로 전환해주는 현상을 말한다. 일반적으로, 유기 발광 소자(organic light emitting device; OLED)는 스스로 발광하는 유기물질을 이용한 디스플레이로서, 유기물질에 전기장을 걸어주면 전자(electron) 및 정공(hole)이 각각 음극 및 양극에서 전달되어 유기물질 내에서 결합하고, 이때 생성되는 에너지가 빛으로 방출되는 유기물 전기발광을 이용한다. The organic light emitting phenomenon refers to a phenomenon in which electrical energy is converted to light energy using organic materials. In general, an organic light emitting device (OLED) is a display using an organic material that emits light by itself. When an electric field is applied to an organic material, electrons and holes are transmitted from the cathode and the anode, respectively, and are organic. It uses organic electroluminescence that combines in a material, and the energy generated at this time is emitted as light.

즉, 유기 발광 소자는 2개의 전극 사이에 발광할 수 있는 유기물에 박막 형태로 끼워지는 구조로 이루어지는데, 유기 박막을 어떤 방식으로 형성하는가에 따라 크게 진공 증착형과 용액 공정형으로 구분된다.That is, the organic light emitting device is made of a structure that is sandwiched in the form of a thin film on an organic material that can emit light between two electrodes, and is largely divided into a vacuum deposition type and a solution processing type depending on how the organic thin film is formed.

진공증착법은 분자량이 낮은 저분자 재료에 적합한 공정으로 10-6 torr 이하의 고진공에서 재료에 열을 가하면 재료가 기체화되어 챔버 내부에서 분산되어 상대적으로 온도가 낮은 기판에 응축되어 박막을 형성하는 공정이다.Vacuum deposition is a process suitable for low molecular weight materials with low molecular weight. When heat is applied to a material at a high vacuum of 10 -6 torr or less, the material is vaporized and dispersed inside the chamber to condense on a relatively low temperature substrate to form a thin film. .

진공증착법은 소자의 높은 수명과 우수한 효율 특성을 구현하기가 용이하여 현재 기업에서는 가장 많이 사용하는 방법이지만, 진공증착법을 이용한 유기 발광 소자 제조 시 화소 패턴 형성에 사용되는 재료의 양이 마스크에 응축되거나, 챔버 내부 벽면에 응축되는 양보다 적기 때문에 10% 가량의 낮은 재료 사용 효율을 보인다.The vacuum deposition method is the most commonly used method in the current enterprise because it is easy to realize the high lifespan and excellent efficiency characteristics of the device, but when the organic light emitting device is manufactured using the vacuum deposition method, the amount of material used to form the pixel pattern is condensed on the mask or , Because it is less than the amount of condensation on the inner wall of the chamber, it shows a low material use efficiency of about 10%.

또한, 생산량 증가 및 생산 단가 감소를 위해서 요구되는 기판 사이즈의 증가에 따른 기하급수적인 장비 운영 비용 증가는 생산 단가를 낮추는데 있어 난제로 작용하고 있으며, 대면적화됨에 따른 마스크 처짐 현상으로 해상도 저하가능성이 큰 문제가 있었다.In addition, the exponential equipment operation cost increase due to the increase in the substrate size required to increase the production volume and decrease the production cost acts as a challenge in lowering the production cost, and the possibility of resolution deterioration is large due to the sagging phenomenon caused by the large area. There was a problem.

한편, 분자량이 낮은 재료와 분자량이 높은 고분자 재료에 모두 사용할 수 있는 방법으로는 용액공정법이 있으며, 용액공정법의 대표적인 방법은 잉크젯 프린팅법과 스핀 코팅법이 있다. On the other hand, a method that can be used for both a low molecular weight material and a high molecular weight polymer material is a solution processing method, and typical methods of the solution processing method include inkjet printing and spin coating.

용액공정법은 재료를 용매에 녹여 잉크화시켜 박막을 형성하는 방법으로 잉크젯 프린팅법을 사용할 경우 재료 사용 효율을 극대화시킬 수 있으며, 마스크를 사용하지 않고 미세 패턴이 가능하기 때문에 대면적화에 유리한 제조법으로 활용할 수 있다는 장점이 있다. The solution process method is a method of forming a thin film by dissolving an ink in a solvent to form a thin film. When using the inkjet printing method, the efficiency of material use can be maximized, and a fine pattern is possible without using a mask. It has the advantage of being usable.

그러나, 가교결합이 없는 용액공정은 상부막의 형성시, 사용되는 용매로 인해 하부막을 침식시켜 하부막을 손상시키는 문제가 있기 때문에, 소자의 특성저하 및 공정 수율의 저하 문제를 야기하며, 상부막의 형성시 하부막의 침식을 막기 위해서 가교결합이 필수적으로 요구된다. 또한, 가교결합 형성 이전에는 유기 용매에 대한 높은 용해도를 가지며 가교 결합 형성 이후에는 유기용매에 대한 낮은 용해도를 갖는, 가교 결합 형성 가능한 화합물을 사용하여야 한다.However, the solution process without cross-linking causes a problem of deteriorating the properties of the device and lowering of the process yield, since there is a problem of eroding the lower film due to the solvent used during formation of the upper film, resulting in a problem of deterioration of the properties of the device and a decrease in process yield. Crosslinking is essential to prevent erosion of the underlying membrane. In addition, it is necessary to use a compound capable of forming a crosslink, which has a high solubility in an organic solvent before crosslinking and a low solubility in an organic solvent after crosslinking.

이와 관련한 종래 기술로서, 한국등록특허공보 제10-1105242호(2012.01.13)는 용액공정이 가능한 청색 발광화합물에 관한 것으로, 피콜리닉산 또는 피콜리닉산-엔-옥사이드 유도체를 보조리간드로 갖는 이리듐계 청색 발광화합물을 개시하고 있고, 또한 한국공개특허공보 제10-2015-0105201호(2015.09.16)는 신규한 유기발광 화합물에 관한 것으로, 카바졸계 유기화합물을 개시하고 있다. As a related art, Korean Registered Patent Publication No. 10-1105242 (2012.01.13) relates to a blue light-emitting compound capable of a solution process, iridium having a picolinic acid or picolinic acid-en-oxide derivative as an auxiliary ligand. Disclosed is a blue light-emitting compound, and Korean Patent Publication No. 10-2015-0105201 (2015.09.16) relates to a novel organic light-emitting compound, and discloses a carbazole-based organic compound.

그러나 상기 선행기술을 포함하는 종래기술에도 불구하고, 아직까지 용액 공정이 가능한 안정하고 효율적인 유기 발광 소자용 재료의 개발이 충분히 이루어지지 않은 상태이며, 따라서 새로운 재료의 개발 필요성은 지속적으로 요구되고 있다.However, in spite of the prior art including the above-described prior art, the development of a stable and efficient material for an organic light-emitting device capable of a solution process has not been sufficiently performed, and thus, the need to develop a new material is continuously required.

상기와 같이 실시예 1 내지 실시예 8 및 비교예 1의 유기 발광 소자들에 순바이어스 직류전압을 가하여 포토리서치(photoresearch)사의 PR-650으로 전기발광(EL) 특성을 측정하였으며, 그 측정 결과 300cd/m2 기준 휘도에서 맥사이언스사에서 제조된 수명 측정 장비를 통해 T90 수명을 측정하고 그 결과를 하기 표 2에 나타내었다. T90은 휘도가 초기휘도에서 90%로 감소되는데 소요되는 시간을 의미한다.Electroluminescence (EL) characteristics were measured by photoresearch PR-650 by applying a direct bias DC voltage to the organic light emitting diodes of Examples 1 to 8 and Comparative Example 1 as described above, and the measurement result was 300 cd. T90 lifespan was measured through a lifespan measuring device manufactured by Max Science at /m2 reference luminance and the results are shown in Table 2 below. T90 is required to reduce the luminance from the initial luminance to 90%. It means time.
