Description

TECHNICAL FIELD [0001] The present invention relates to a compound for a novel organic electroluminescent device and an organic electroluminescent device including the same. BACKGROUND OF THE INVENTION [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a compound for an organic electroluminescent device and an organic electroluminescent device including the same, and more particularly to a compound for an organic electroluminescent device capable of improving the luminous efficiency of the organic electroluminescent device, Device.

As the move to the information society accelerates, the proportion of flat panel displays is gradually increasing. LCD (liquid crystal display) is the most widely used method, but it is a method to make a screen by applying voltage to liquid crystal and passing light from backlight through color filter to obtain three primary colors. Organic light emitting diodes (OLED) As a self-luminous element, it has excellent viewing angle and contrast ratio, is lightweight and thin, can be used for a substrate having a bending property, and is capable of transparent and flexible display, and has attracted attention as a next generation display element.

Organic EL is a phenomenon in which excitons are formed by recombination of electrons and holes injected through a cathode and an anode into an organic thin film, and light of a specific wavelength is generated from the excitons formed. In 1963, Pope et al. Reported that an anthracene single crystal (CW Tang, SA Vanslyke, Applied Physics Letters, Vol. 51, No. 913p, 1987) by Eastman Kodak Co., Ltd. (CW Tang) et al.

Organic materials used in organic electroluminescent devices are classified into polymer and small molecule, and small molecules can be divided into pure organic material and metal complex which forms metal and chelate.

Polymers can combine diverse functional units into polymer chains to produce multifunctional materials. However, it is difficult to purify compounds or to form devices, while low-molecular materials can synthesize materials of various properties. There is a limit to the synthesis of the substances.

The organic electroluminescent device can be formed in a laminated structure. In general, the device structure is formed by forming a hole injecting layer, a hole transporting layer, a light emitting layer, an electron transporting layer, and an electron injecting layer between an anode and a cathode to form a light emitting layer The exciton formation can be facilitated and the emission efficiency can be enhanced.

The luminescent material can be roughly divided into a host material and a luminescent material (dopant) material, and the luminescent material is distinguished by fluorescence and phosphorescence depending on the luminescence mechanism.

The excited state of the electrons in the compound is 1: 3 ratio of singlet to triplet, and triplet state is generated about 3 times more. Thus, the internal quantum efficiency of phosphorescence falling from the triplet state to the base state is 75% while the internal quantum efficiency of the fluorescence falling from the singlet state to the ground state is only 25%. In addition, the theoretical limit of internal quantum efficiency reaches 100% when the interplanar transition from singlet state to triplet state occurs. A light emitting material that improves the light emitting efficiency by using this point is a phosphorescent material.

Due to the nature of organic materials, it is difficult to emit phosphorescence. As a phosphorescent material, transition metal (iridium) is utilized as an organometallic compound, and an organic material is used as a host material to assist it. The material that assists the phosphorescent material (host) should have a wide bandgap and a high triplet state energy. A phosphorescent material having excellent current efficiency and luminous efficiency is received in the spotlight, but the electron transporting ability, the hole transporting ability, the host material which is thermally and electrically stable, and the organic electroluminescent device It is necessary to develop a compound for use.

The present invention relates to a compound capable of being used for a light emitting layer as a host which is excellent in electrical stability, electron and hole transporting ability, and has high triplet state energy and can improve the luminous efficiency of a phosphorescent light emitting material, A light emitting element can be provided.

In addition, the present invention can provide an organic electroluminescent compound that can be used for an electron transporting material and a hole transporting material of an organic electroluminescent device, and an organic electroluminescent device including the same.
