Description

Novel fluorene derivatives and organic electronic devices using the same {NEW FLUORENE DERIVATIVES AND ORGANIC ELECTRONIC DEVICES USING THE SAME}

The present invention relates to a novel fluorene derivative having a heteroaryl group bonded to a novel fluorene and an organic electronic device using the same.

The organic electronic device refers to a device that requires charge exchange between an electrode and an organic material using holes and / or electrons. The organic electronic device can be divided into two types according to the operation principle. First, an exciton is formed in the organic layer by photons introduced into the device from an external light source, and the exciton is separated into electrons and holes, and these electrons and holes are transferred to different electrodes to be used as current sources (voltage sources). It is an electronic device of the form. The second type is an electronic device in which holes and / or electrons are injected into an organic semiconductor forming an interface with the electrodes by applying voltage or current to two or more electrodes, and operated by the injected electrons and holes.

Examples of the organic electronic device include an organic light emitting device, an organic solar cell, an organic photoconductor (OPC), an organic transistor, etc., all of which are used to inject or transport holes, inject or transport electrons, or light emitting materials for driving the device. need. Hereinafter, the organic light emitting device will be described in detail. However, in the organic electronic devices, a hole injection or transport material, an electron injection or transport material, or a light emitting material functions on a similar principle.

In general, organic light emitting phenomenon refers to a phenomenon of converting electrical energy into light energy using an organic material. An organic light emitting device using an organic light emitting phenomenon usually has a structure including an anode, a cathode and an organic material layer therebetween. The organic material layer is often made of a multi-layered structure composed of different materials in order to increase the efficiency and stability of the organic light emitting device, for example, it may be made of a hole injection layer, a hole transport layer, a light emitting layer, an electron transport layer, an electron injection layer. When the voltage is applied between the two electrodes in the structure of the organic light emitting diode, holes are injected into the organic material layer at the anode and electrons are injected into the organic material layer, and excitons are formed when the injected holes and electrons meet. When it falls back to the ground, it glows. Such organic light emitting diodes are known to have characteristics such as self-luminous, high brightness, high efficiency, low driving voltage, wide viewing angle, high contrast and high speed response.

Materials used as the organic material layer in the organic light emitting device may be classified into light emitting materials and charge transport materials such as hole injection materials, hole transport materials, electron transport materials, electron injection materials and the like depending on their functions. In addition, the light emitting materials include blue, green, and red light emitting materials, and yellow and orange light emitting materials required to realize better natural colors depending on the color of light emitted. On the other hand, when only one material is used as a light emitting material, there arises a problem that the maximum light emission wavelength shifts to a long wavelength due to intermolecular interaction, the color purity decreases, or the efficiency of the device decreases due to the light emission attenuating effect. A host / dopant system may be used as the light emitting material in order to increase the light emitting efficiency through the light emitting layer.

In order for the organic light emitting device to fully exhibit the above-mentioned excellent characteristics, it is supported that a material that forms the organic material layer in the device, such as a hole injection material, a hole transport material, a light emitting material, an electron transport material, an electron injection material, etc. is supported by a stable and efficient material. Although it should be preceded, the development of a stable and efficient organic material layer for an organic light emitting device has not been made yet. Therefore, the development of new materials continues to be demanded, and the necessity of such material development is the same in other organic electronic devices described above.

Thus, the inventors have discovered a fluorene derivative having a novel structure. In addition, it has been found that when the organic material layer of the organic electronic device is formed using the novel fluorene derivative, effects such as efficiency increase, driving voltage drop, and stability increase of the device may be exhibited.

Accordingly, an object of the present invention is to provide a novel fluorene derivative and an organic electronic device using the same.
