COMPOUND AND ORGANIC LIGHT EMITTING DEVICE COMPRISING SAME

TECHNICAL FIELD

The present specification relates to a compound and an organic light emitting device including the same.

BACKGROUND ART

In the present specification, an organic light emitting device is a light emitting device using an organic semiconductor material, and requires an exchange of holes and/or electrons between electrodes and organic semiconductor materials. The organic light emitting device may be roughly divided into the following two organic light emitting devices depending on the operation principle. The first organic light emitting device is a light emitting device in which an exciton is formed in an organic material layer by a photon that flows from an external light source to the device, the exciton is separated into electrons and holes, and the electrons and the holes are each transferred to different electrodes and used as a current source (voltage source). The second organic light emitting device is a light emitting device in which holes and/or electrons are injected into organic semiconductor material layers forming an interface with an electrode by applying a voltage or current to two or more electrodes, and the device is operated by the injected electrons and holes.

In general, an organic light emitting phenomenon refers to a phenomenon in which electric energy is converted into light energy by using an organic material. An organic light emitting device using the organic light emitting phenomenon usually has a structure including a positive electrode, a negative electrode, and an organic material layer interposed therebetween. Here, the organic material layer has in many cases a multi-layered structure composed of different materials in order to improve the efficiency and stability of the organic light emitting device, and for example, may be composed of a hole injection layer, a hole transport layer, a light emitting layer, an electron blocking layer, an electron transport layer, an electron injection layer, and the like. In such a structure of the organic light emitting device, if a voltage is applied between the two electrodes, holes are injected from the positive electrode into the organic material layer and electrons are injected from the negative electrode into the organic material layer, and when the injected holes and electrons meet each other, an exciton is formed, and light is emitted when the exciton falls down again to a ground state. Such an organic light emitting device has been known to have characteristics such as self-emission, high brightness, high efficiency, a low driving voltage, a wide viewing angle, and high contrast.

In an organic light emitting device, materials used as an organic material layer may be classified into a light emitting material and a charge transport material, for example, a hole injection material, a hole transport material, an electron blocking material, an electron transport material, an electron injection material, and the like depending on the function. The light emitting materials include blue, green, and red light emitting materials according to the light emitting color, and yellow and orange light emitting materials required for implementing a much better natural color.

Furthermore, a host/dopant system may be used as a light emitting material for the purpose of enhancing color purity and light emitting efficiency through energy transfer. The principle is that when a small amount of dopant which has a smaller energy band gap and better light emitting efficiency than those of a host mainly constituting a light emitting layer is mixed in the light emitting layer, the excitons generated by the host are transported to the dopant to emit light with high efficiency. In this case, it is possible to obtain light with a desired wavelength according to the type of dopant used because the wavelength of the host moves to the wavelength range of the dopant.

In order to fully exhibit the above-described excellent characteristics of the organic light emitting device, a material constituting an organic material layer in a device, for example, a hole injection material, a hole transport material, a light emitting material, an electron blocking material, an electron transport material, an electron injection material, and the like need to be supported by stable and efficient materials, so that there is a continuous need for developing a new material.

The light emitting layer may emit red, green, or blue light, and may be composed of a phosphorescent material or a fluorescent material. The light emitting material is a material which may receive holes and electrons from a hole transport layer and an electron transport layer, respectively, and combine the holes and the electrons to emit light in a visible ray region, and is preferably a material having high quantum efficiency for fluorescence or phosphorescence.

In this case, a product manufactured by Fischer Co., was used as the detergent, and distilled water twice filtered using a filter manufactured by Millipore Co., was used as the distilled water. After the ITO was washed for 30 minutes, ultrasonic washing was conducted twice repeatedly using distilled water for 10 minutes. After the washing using distilled water was completed, ultrasonic washing was conducted by using isopropyl alcohol, acetone, and methanol solvents, and the resulting product was dried and then transported to a plasma washing machine. Furthermore, the substrate was cleaned by using oxygen plasma for 5 minutes, and then was transported to a vacuum deposition machine.

The following HI-A and HAT were thermally vacuum deposited to have a thickness of 650 Å and 50 Å, respectively, on the ITO transparent electrode prepared as described, thereby forming first and second hole injection layers. The following HT-A was vacuum deposited to have a thickness of 600 Å on the hole injection layer, thereby forming a hole transport layer.

The following HT-B was vacuum deposited to have a thickness of 50 Å on the hole transport layer, thereby forming an electron blocking layer. Subsequently, 2 parts by weight of Compound 1 (C-1) of the present invention as a blue light emitting dopant based on 100 parts by weight of the light emitting layer and the following BH as a host were vacuum deposited to have a thickness of 200 Å on the electron blocking layer, thereby forming a light emitting layer. Next, the following compound ET-A as a first electron transport layer was vacuum deposited to have a thickness of 50 Å on the light emitting layer, and subsequently, the following ET-B and LiQ were vacuum deposited at a weight ratio of 1:1, thereby forming a second electron transport layer having a thickness of 360 Å. LiQ was vacuum deposited on the second electron transport layer, thereby forming an electron injection layer having a thickness of 5 Å. Aluminum and silver were deposited at a weight ratio of 10:1 to have a thickness of 220 Å on the electron injection layer, aluminum was deposited to have a thickness of 1,000 Å thereon, thereby forming a negative electrode.

In the aforementioned procedure, the deposition rate of the organic materials were maintained at 0.4 to 0.9 Å/sec, the deposition rate of aluminum of the negative electrode was maintained at 2 Å/sec, and the degree of vacuum during the deposition was maintained at 1×10⁻⁷to 1×10⁻⁸torr, thereby manufacturing an organic light emitting device.
