Description

Anthracene derivatives and organic light-emitting diodes including the same

The present invention relates to an anthracene derivative and an organic electroluminescent device comprising the same, and more particularly, an anthracene derivative capable of implementing low voltage driving and long life and excellent organic light emitting efficiency when employed in an organic electroluminescent device, and an organic electroluminescence comprising the same. It relates to an element.

Recently, the organic electroluminescent device capable of low voltage driving with self-luminous type has better viewing angle, contrast ratio, etc., no backlight, light weight and thinness, advantageous in terms of power consumption, and color reproduction, compared to the liquid crystal display, which is the mainstream of flat panel display devices. The range is attracting attention as a next generation display device.

In organic light emitting diodes (OLEDs), when electrons are injected into an organic light emitting layer formed between an electron injection electrode (cathode) and a hole injection electrode (anode), electrons and holes are paired, to be.

The organic light emitting diode can be formed on a transparent substrate such as plastic, and can be driven at a voltage lower than 10 V, and consumes less power than a plasma display panel or an inorganic electroluminescent display. It has the advantage of excellent color. In addition, organic electroluminescent devices are capable of displaying three colors of green, blue, and red, and thus are attracting much attention as next-generation rich color display devices.

The most important factor determining the luminous efficiency in an organic electroluminescent device is a light emitting material. Fluorescent materials are widely used as the light emitting materials. However, the development of phosphorescent materials is one of the methods for improving the luminous efficiency theoretically. Therefore, various phosphorescent materials have been developed to date.

However, the organic EL device using the phosphorescent material is considerably higher in current efficiency than the device using the fluorescent light emitting material. However, in the case of using the conventional phosphorescent material, materials such as BAlq and CBP, which are known as conventional phosphorescent light emitting hosts, may be used. When used, the driving voltage is higher than the device using the fluorescent material, so there is no great advantage in terms of power efficiency, and it is not satisfactory in terms of the lifetime of the device, and also Alq, which is known as an electron transport material for phosphorescence emission. _{In the} case of using ₃ , the difference in energy level with the electron injection layer or the cathode is not only low, the luminous efficiency is lowered, and there is a problem of increasing the driving voltage of the device, and thus, development of a more stable high-performance phosphorescent material is required.

Accordingly, an object of the present invention is to solve the above problems, and to provide an organic light emitting compound having better luminous efficiency than conventional materials and at the same time having improved power efficiency and long life characteristics.

The electron transport layer serves to increase the chance of recombination within the light emitting layer by smoothly transporting electrons supplied from the cathode to the organic light emitting layer and suppressing the movement of holes that are not bonded in the organic light emitting layer. The organic light emitting device according to the present invention comprises at least one anthracene derivative compound implemented in the formula [1] in the electron transport layer.

Currently, oxadiazole derivatives such as PBD, BMD, BND, or Alq ₃ are used as the electron transport layer material. However, since the energy level difference with the electron injection layer or the cathode is large, the luminous efficiency is lowered and the driving voltage of the device is increased. Although a problem occurs, when the anthracene derivative compound according to the present invention is used, the electron transport ability is improved to lower the driving voltage, thereby improving power efficiency and increasing luminous efficiency.

On the other hand, an electron injection layer (EIL) may be further formed on the electron transport layer to facilitate injection of electrons from the cathode to ultimately improve power efficiency. As long as it is commonly used in the art, it can be used without any particular limitation. For example, materials such as LiF, NaCl, CsF, Li ₂ O, and BaO can be used.

The organic light emitting display device according to an embodiment of the present invention may be used for a display device, a display device, and a monochrome or white lighting device.

1 is a cross-sectional view showing the structure of an organic light emitting display device according to the present invention. The organic light emitting diode according to the present invention includes an anode 20, a hole transport layer 40, an organic light emitting layer 50, an electron transport layer 60 and a cathode 80, and if necessary, the hole injection layer 30 and the electron The injection layer 70 may be further included. In addition, an intermediate layer of one or two layers may be further formed, and a hole blocking layer or an electron blocking layer may be further formed.

Referring to FIG. 1, the organic electroluminescent device of the present invention and its manufacturing method will be described as follows. First, the anode 20 is formed by coating an anode electrode material on the substrate 10. As the substrate 10, a substrate used in a conventional organic EL device is used. An organic substrate or a transparent plastic substrate excellent in transparency, surface smoothness, ease of handling, and waterproofness is preferable. As the material for the anode electrode, indium tin oxide (ITO), indium zinc oxide (IZO), tin oxide (SnO 2), and zinc oxide (ZnO), which are transparent and excellent in conductivity, are used.

The hole injection layer 30 is formed by vacuum-heat deposition or spin coating of the hole injection layer material on the anode 20 electrode. Next, the hole transport layer 40 is formed by vacuum thermal evaporation or spin coating of the hole transport layer material on the hole injection layer 30. Subsequently, the organic light emitting layer 50 is stacked on the hole transport layer 40, and a hole blocking layer (not shown) is selectively formed on the organic light emitting layer 50 by a vacuum deposition method or a spin coating method. can do. When the holes pass through the organic light emitting layer and enter the cathode, the lifetime and efficiency of the hole blocking layer are reduced. Therefore, the hole blocking layer plays a role of preventing such a problem by using a material having a very low HOMO level. The hole blocking material used herein is not particularly limited, but it is required to have an ionization potential higher than that of a light emitting compound while having an electron transporting ability. Typically, BAlq, BCP, TPBI and the like can be used.

After the electron transport layer 60 is deposited on the hole blocking layer through a vacuum deposition method or a spin coating method, an electron injection layer 70 is formed and a cathode forming metal is vacuum-heated on the electron injection layer 70. The organic EL device is completed by vapor deposition to form a cathode 80 electrode. Here, as the metal for forming the cathode, lithium, magnesium, aluminum, aluminum-lithium, calcium, magnesium-magnesium, Mg-Ag), and a transmissive cathode using ITO or IZO can be used to obtain a top light-emitting device.

Hereinafter, the present invention will be described in more detail with reference to the following examples, but the following examples are for illustrative purposes only and are not intended to limit the present invention.
