Description

A novel compound for an organic light emitting device and a coating solution composition for an organic film material comprising the same

The present invention relates to a novel compound for an organic light emitting device and a coating solution composition for an organic film material comprising the same, and more particularly, a solution process is possible, and when used in an organic light emitting device, high luminous efficiency, low voltage driving, high heat resistance , to a compound for an organic light emitting device capable of realizing device characteristics such as high solvent resistance, color purity and long life, and a coating solution composition for an organic film material comprising the same.

The organic light emitting phenomenon is one example in which electric current is converted into visible light by an internal process of a specific organic molecule. The principle of organic light emitting phenomenon is as follows. When an organic material layer is placed between the anode and the cathode, if a current is applied between the two electrodes, electrons and holes are respectively injected into the organic material layer from the cathode and the anode. Electrons and holes injected into the organic layer recombine to form excitons, and the excitons fall back to the ground state and emit light. An organic light emitting device using this principle may generally include a cathode, an anode, and an organic layer positioned therebetween, for example, an organic layer including a hole injection layer, a hole transport layer, a light emitting layer, and an electron transport layer.

That is, the organic light emitting device has a structure that is sandwiched between two electrodes in the form of a thin film on an organic material capable of emitting light, and is largely divided into a vacuum deposition type and a solution process type depending on how the organic thin film is formed.

The vacuum deposition method is a process suitable for low molecular weight materials with low molecular weight ^{. When heat is applied to the material in a high vacuum of 10 -6} torr or less, the material is vaporized and dispersed in the chamber, condensed on a relatively low temperature substrate to form a thin film. .

The vacuum deposition method is currently the most used method by companies because it is easy to realize high lifespan and excellent efficiency characteristics of the device. , it shows a low material use efficiency of about 10% because it is less than the amount of coagulation on the inner wall of the chamber.

In addition, the exponential increase in equipment operating cost due to the increase in the size of the substrate required to increase production and reduce production cost is a challenge in lowering the production cost, and there is a high possibility of resolution degradation due to mask sagging due to large area. There was a problem.

Meanwhile, as a method that can be used for both a low molecular weight material and a high molecular weight polymer material, there is a solution process method, and representative methods of the solution process method include an inkjet printing method and a spin coating method.

The solution process method is a method of forming a thin film by dissolving a material in a solvent and turning it into ink. When the inkjet printing method is used, the material use efficiency can be maximized, and a fine pattern is possible without the use of a mask. It has the advantage of being able to use it.

However, since the solution process without crosslinking has a problem of eroding the lower film and damaging the lower film due to the solvent used when forming the upper film, it causes deterioration of device characteristics and lowering process yield, and when the upper film is formed Crosslinking is essential to prevent erosion of the underlying film. In addition, it is necessary to use a compound capable of forming a cross-link, which has high solubility in an organic solvent before cross-link formation and low solubility in organic solvent after cross-link is formed.

There are two major methods for forming a crosslink: a crosslinking method through light and a crosslinking method through heat. Crosslinking by light has the advantage of being able to crosslink quickly at low temperatures, but it requires a photoinitiator, which acts as an impurity in the device, which leads to deterioration of properties. On the other hand, crosslinking through heat requires a high temperature for a long time, but is known to improve device properties.

As a related art, Korean Patent Publication No. 10-1105242 (Jan. 13, 2012) relates to a blue light-emitting compound capable of a solution process, and iridium having picolinic acid or a picolinic acid-ene-oxide derivative as an auxiliary ligand.

However, in spite of the prior art including the 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 developed.
