Description
본 발명은 잉크젯 공정에 적용할 수 있는 유기 발광 소자용 잉크 조성물에 관한 것이다. The present invention relates to an ink composition for an organic light-emitting device that can be applied to an inkjet process.
일반적으로 유기 발광 현상이란 유기 물질을 이용하여 전기에너지를 빛에너지로 전환시켜주는 현상을 말한다. 유기 발광 현상을 이용하는 유기 발광 소자는 넓은 시야각, 우수한 콘트라스트, 빠른 응답 시간을 가지며, 휘도, 구동 전압 및 응답 속도 특성이 우수하여 많은 연구가 진행되고 있다. In general, organic luminescence refers to a phenomenon that converts electrical energy into light energy using organic materials. Organic light-emitting devices using the organic light-emitting phenomenon have a wide viewing angle, excellent contrast, fast response time, and excellent luminance, driving voltage, and response speed characteristics, so much research is being conducted.
유기 발광 소자는 일반적으로 양극과 음극 및 상기 양극과 음극 사이에 유기물 층을 포함하는 구조를 가진다. 상기 유기물 층은 유기 발광 소자의 효율과 안정성을 높이기 위하여 각기 다른 물질로 구성된 다층의 구조로 이루어진 경우가 많으며, 예컨대 정공주입층, 정공수송층, 발광층, 전자수송층, 전자주입층 등으로 이루어질 수 있다. 이러한 유기 발광 소자의 구조에서 두 전극 사이에 전압을 걸어주게 되면 양극에서는 정공이, 음극에서는 전자가 유기물층에 주입되게 되고, 주입된 정공과 전자가 만났을 때 엑시톤(exciton)이 형성되며, 이 엑시톤이 다시 바닥상태로 떨어질 때 빛이 나게 된다. Organic light emitting devices generally have a structure including an anode, a cathode, and an organic layer between the anode and the cathode. The organic material layer is often composed of a multi-layer structure made of different materials to increase the efficiency and stability of the organic light-emitting device, and may be composed of, for example, a hole injection layer, a hole transport layer, a light-emitting layer, an electron transport layer, and an electron injection layer. In the structure of this organic light-emitting device, when a voltage is applied between the two electrodes, holes are injected from the anode and electrons from the cathode into the organic material layer. When the injected holes and electrons meet, an exciton is formed, and this exciton is When it falls back to the ground state, it glows.
한편, 최근에는 공정 비용 절감을 위하여 기존의 증착 공정 대신 용액 공정, 특히 잉크젯 공정을 이용한 유기 발광 소자가 개발되고 있다. 초창기에는 모든 유기 발광 소자 층을 용액 공정으로 코팅하여 유기 발광 소자를 개발하려 하였으나 현재 기술로는 한계가 있어, 정구조 형태에서 HIL, HTL, EML만을 용액 공정으로 진행하고 추후 공정은 기존의 증착 공정을 활용하는 하이브리드(hybrid) 공정이 연구 중이다. Meanwhile, recently, in order to reduce process costs, organic light-emitting devices have been developed using a solution process, especially an inkjet process, instead of the existing deposition process. In the early days, attempts were made to develop organic light emitting devices by coating all organic light emitting device layers using a solution process, but there are limitations to the current technology, so only HIL, HTL, and EML in the form of a fixed structure were performed using a solution process, and the subsequent processes were carried out using the existing deposition process. A hybrid process utilizing is being studied.
잉크젯 공정을 이용하여 유기 발광 소자의 기능층을 형성하는 경우, 정밀도를 위하여 잉크가 헤드의 노즐에서 안정하게 토출되어야 하며, 도포된 후 건조되는 과정에서 균일하면서도 평탄한 막을 형성하여야 한다. 예를 들어, 격벽으로 둘러싸인 기능층 형성 영역에 잉크를 도포한 후 건조시키면, 잉크 막이 불균일하게 고화되는 경우에는 막 편탕성을 확보하기 어려운데, 특히 중심부의 막 두께가 격벽측 보다 두꺼워지거나(볼록한 모양), 중심부보다 격벽측 막두께가 두꺼워지는 현상(오목한 모양)이 발생하는 경우가 많다.When forming the functional layer of an organic light-emitting device using an inkjet process, ink must be stably discharged from the nozzle of the head for precision, and a uniform and flat film must be formed during application and drying. For example, when ink is applied to the functional layer formation area surrounded by a partition and then dried, it is difficult to ensure film dispersibility if the ink film solidifies unevenly. In particular, the film thickness at the center becomes thicker than that on the partition side (convex shape). ), a phenomenon in which the membrane thickness on the septum side becomes thicker than the center (concave shape) often occurs.
따라서, 잉크젯 공정을 적용함에 있어, 상기의 문제를 해결할 수 있는 유기 발광 소자용 잉크 조성물의 개발이 요구된다. Therefore, when applying the inkjet process, there is a need to develop an ink composition for organic light-emitting devices that can solve the above problems.

용매menstruum
상기 화학식 1로 표시되는 화합물을 용액 공정으로 기능층을 형성할 수 있는데, 최근에는 용액 공정 중에서도 잉크젯 프린팅(inkjet printing) 공정이 가장 많이 검토되고 있다. 잉크젯 프린팅 공정은 미세 drop을 토출하기 때문에, 재료의 소모량을 최소화할 수 있을 뿐만 아니라 정밀 패턴이 가능하다는 이점이 있다. A functional layer can be formed using the compound represented by Formula 1 through a solution process. Recently, among the solution processes, the inkjet printing process is being considered the most. Since the inkjet printing process ejects fine drops, it has the advantage of minimizing material consumption and enabling precise patterns.
용액 공정으로 평탄한 기능층을 제조하기 위해서는 기본적으로 잉크의 공정성과 막 표면 이미지, 막 평탄성을 동시에 확보해야 한다. 잉크 조성물은 대부분 용매로 이루어져 있으며(최소 90%, 최대 99.9%), 용매에 의해 잉크 물성이 결정되기 때문에 용매의 선택이 무엇보다 중요하다.In order to manufacture a flat functional layer through a solution process, the fairness of the ink, the film surface image, and the film flatness must be secured at the same time. The ink composition is mostly composed of solvent (minimum 90%, maximum 99.9%), and since the ink physical properties are determined by the solvent, the selection of solvent is most important.
잉크의 공정성은 잉크젯 장비의 노즐에서 잉크가 마르는 현상 없이 안정적으로 토출될 수 있는 특성이며, 이를 위해서는 증기압이 충분히 낮은 고비점 특성을 갖는 용매를 선택해야 한다. 잉크 막 이미지는 기능층 제조 과정에서 건조 과정을 거칠 때, 석출/상분리 없이 표면이 균일한 막 이미지를 형성하는 특성이며, 이를 위해서는 기능층의 재료를 충분히 용해할 수 있는 높은 용해도 특성과 진공 건조에 적합한 건조 특성을 갖는 용매를 선택해야 한다. 또한, 막 이미지와 동시에 요구되는 특성은 막 평탄성이다. 기능층은 여러 개의 적층 구조로 형성되기 때문에 각 기능층이 평탄하게 형성되어야, 완성된 유기 발광 소자에서 안정적인 발광 특성을 낼 수 있다. 따라서, 잉크 조성물에서 잉크 공정성, 막 이미지, 및 막 평탄성을 동시에 확보할 수 있는 용매 선택이 중요하다. 이에 본 발명에서는 상술한 용매를 사용함으로써, 상기의 특성을 구현할 수 있다. Fairness of ink is a characteristic that allows ink to be stably discharged from the nozzle of inkjet equipment without drying out, and for this, a solvent with sufficiently low vapor pressure and high boiling point characteristics must be selected. The ink film image is a characteristic that forms a film image with a uniform surface without precipitation/phase separation when going through the drying process in the functional layer manufacturing process. This requires high solubility characteristics that can sufficiently dissolve the material of the functional layer and vacuum drying. A solvent with suitable drying properties should be selected. Additionally, a characteristic required along with the membrane image is membrane flatness. Since the functional layer is formed of several stacked structures, each functional layer must be formed flat to produce stable light emission characteristics in the completed organic light emitting device. Therefore, it is important to select a solvent that can simultaneously secure ink processability, film image, and film flatness in the ink composition. Accordingly, in the present invention, the above characteristics can be realized by using the above-described solvent.
본 발명에서 사용되는 용매는 log P가 1.5 이상이고, 분자 부피가 190 cm3/mole 이하라는 특징이 있다. The solvent used in the present invention has log P of 1.5 or more and a molecular volume of 190 cm 3 /mole or less.
상기 "log P"란, 물과 옥탄올의 분배계수를 의미하는 것으로, 실험적으로 측정하거나 또는 이론적으로 예측 가능하며, 각 용매의 고유 물성이다. 상기 용매의 log P가 1.5 미만인 경우에는, 잉크 조성물을 건조하는 과정에서 앞서 설명한 화학식 1로 표시되는 화합물이 결정으로 석출되는 문제가 있다. 한편, 상기 용매의 log P의 상한은 특별히 제한되지 않으나, 바람직하게는 11.5 이하, 11.0 이하, 10.5 이하, 또는 10.0 이하이다. The “log P” refers to the partition coefficient between water and octanol, which can be measured experimentally or predicted theoretically, and is a unique physical property of each solvent. If the log P of the solvent is less than 1.5, there is a problem in that the compound represented by Chemical Formula 1 described above precipitates as crystals during the process of drying the ink composition. Meanwhile, the upper limit of log P of the solvent is not particularly limited, but is preferably 11.5 or less, 11.0 or less, 10.5 or less, or 10.0 or less.
상기 "분자 부피"란, 분자 1몰이 차지하는 부피를 의미하는 것으로, 본 발명에서는 상온(25℃) 및 상압(1 기압)에서 측정한 값을 의미하며, 각 용매의 고유 물성이다. 상기 용매의 분자 부피가 190 cm3/mole 초과인 경우에는, 잉크 조성물을 건조하는 과정에서 용매의 확산 속도가 낮기 때문에, 앞서 설명한 화학식 1로 표시되는 화합물이 석출되는 문제가 있다. 한편, 상기 용매의 분자 부피의 하한은 특별히 제한되지 않으나, 바람직하게는 100 cm3/mole 이상, 105 cm3/mole 이상, 또는 100 cm3/mole 이상이다. The “molecular volume” refers to the volume occupied by 1 mole of molecules. In the present invention, it refers to the value measured at room temperature (25°C) and normal pressure (1 atm), and is a unique physical property of each solvent. When the molecular volume of the solvent exceeds 190 cm 3 /mole, the diffusion rate of the solvent is low during the process of drying the ink composition, so there is a problem in that the compound represented by Formula 1 described above is precipitated. Meanwhile, the lower limit of the molecular volume of the solvent is not particularly limited, but is preferably 100 cm 3 /mole or more, 105 cm 3 /mole or more, or 100 cm 3 /mole or more.
또한, 본 발명에 따른 용매는 단일 용매일 수 있으며, 혼합 용매일 수 있다. 혼합 용매인 경우에는, 2종 이상의 용매가 이하 수학식 1 및 2의 방법으로 계산된 Log P 및 분자 부피가 상술한 범위를 만족하는 것을 의미한다. Additionally, the solvent according to the present invention may be a single solvent or a mixed solvent. In the case of a mixed solvent, it means that the Log P and molecular volume of two or more solvents calculated by the method of Equations 1 and 2 below satisfy the above-mentioned range.
