Description

TECHNICAL FIELD The present invention relates to an organic electroluminescent compound and an electroluminescent device comprising the same,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an organic light emitting compound, and more particularly, to an organic light emitting compound that is employed as a host compound or a dopant compound in a light emitting layer of an organic electroluminescent device and an organic electroluminescent device .

An organic light emitting phenomenon is a phenomenon that converts electric energy into light energy by using an organic material. An organic electroluminescent device using an organic light emitting phenomenon usually has a structure including an anode, an anode, and an organic material layer therebetween. Here, in order to increase the efficiency and stability of the organic electroluminescent device, the organic material layer may have a multi-layer structure composed of different materials and may include a hole injecting layer, a hole transporting layer, a light emitting layer, an electron transporting layer, . When a voltage is applied between the two electrodes in the structure of the organic electroluminescent device, holes are injected into the anode, electrons are injected into the organic layer, and excitons are formed when injected holes and electrons meet. When it falls back to the ground state, the light comes out. Such an organic electroluminescent device is known to have properties such as self-emission, high luminance, high efficiency, low driving voltage, wide viewing angle, high contrast, and high speed response.

Materials used as an organic material layer in an organic electroluminescent device can be classified into a light emitting material and a charge transporting material, a hole injecting material, a hole transporting material, an electron transporting material, and an electron injecting material depending on functions. In addition, the luminescent material can be classified into blue, green and red luminescent materials and yellow and orange luminescent materials necessary for realizing a better natural color depending on the luminescent color.

On the other hand, when only one material is used as the light emitting material, there arises a problem that the maximum light emitting wavelength shifts to a long wavelength due to intermolecular interaction, the color purity drops, or the efficiency of the device decreases due to the light emission attenuating effect. A host / dopant system may be used as a light emitting material in order to increase the efficiency of light emission through the light emitting layer.

In order for the organic luminescent device to sufficiently exhibit the above-described excellent characteristics, a material constituting the organic material layer in the device, such as a hole injecting material, a hole transporting material, a luminescent material, an electron transporting material and an electron injecting material is supported by a stable and efficient material However, development of a stable and efficient organic material layer material for an organic light emitting device has not been sufficiently developed yet. Therefore, development of new materials is continuously required, and the necessity of developing such materials is the same in other organic electronic devices described above.

As a blue light emitting material, US Pat. No. 7053255 discloses a blue light emitting compound having a diphenyl anthracene structure and an aryl group substituted at the terminal thereof, and an organic electroluminescent device using the blue light emitting compound, but has a problem in that the light emitting efficiency and brightness are not sufficient . On the other hand, US Pat. No. 7233019 and Korean Patent Laid-Open Publication No. 2006-0006760 disclose an organic electroluminescent device using a substituted pyrene compound. However, since the color purity of blue is low, a deep blue It is difficult to realize a full-color full-color display.

The present invention provides a novel organic electroluminescent compound which can be used as a host compound or a dopant compound in a light emitting layer of an organic electroluminescent device to realize excellent luminescent characteristics and an organic electroluminescent device including the same.

In order to solve the above problems, the present invention provides an organic electroluminescent compound having at least one substituent of the following structural formula 1 or structural formula 2 in a core skeleton represented by the following formula 1: An electroluminescent device is provided.
