Description

TECHNICAL FIELD [0001] The present invention relates to an organic compound and an organic electroluminescent device including the organic compound.

The present invention relates to a novel organic compound that can be used as a material of an organic electroluminescent device, and an organic electroluminescent device including the same and having improved luminous efficiency, driving voltage, and life span of the device.

Studies on organic electroluminescent (EL) devices (hereinafter, simply referred to as 'organic EL devices') by blue electroluminescence using anthracene single crystals in 1965 have been carried out with reference to the observation of organic thin film luminosity of Bernanose in the 1950s . In 1987, a layered organic EL device was proposed by Tang divided into a hole layer and a functional layer of a light emitting layer. Thereafter, in order to make a high efficiency and high number of organic EL devices, each organic EL device has been developed in a manner of introducing each characteristic organic material layer in the device, leading to the development of specialized materials used therefor.

In the organic electroluminescent device, when a voltage is applied between two electrodes, holes are injected into the organic layer in the anode, and electrons are injected into the organic layer in the cathode. When the injected holes and electrons meet, an exciton is formed. When the exciton falls to the ground state, light is emitted. At this time, the material used as the organic material layer can be classified into a light emitting material, a hole injecting material, a hole transporting material, an electron transporting material, an electron injecting material and the like depending on its function.

The luminescent material can be classified into blue, green and red luminescent materials according to luminescent colors and yellow and orange luminescent materials necessary for realizing better natural colors. Further, in order to increase the color purity and to increase the luminous efficiency through energy transfer, a host / dopant system can be used as a luminescent material.

The dopant material can be divided into a fluorescent dopant using an organic material and a phosphorescent dopant using a metal complex compound containing heavy atoms such as Ir and Pt. Since the phosphorescent material can theoretically improve the luminous efficiency up to 4 times as much as that of the fluorescent material, studies on phosphorescent host materials as well as phosphorescent dopants have been conducted.

Up to now, hole injecting layer, hole transporting layer. NPB, BCP, and Alq ₃ are widely known as the hole blocking layer and the electron transporting layer, and anthracene derivatives as a luminescent material have been reported as fluorescent dopant / host material. Particularly, phosphorescent materials which have a great advantage in terms of efficiency improvement of light emitting materials include Firpic, Ir (ppy) ₃ , (acac) Ir (btp) as a blue, green, ₂ or the like is used. Up to now, 4,4-dicarbazolybiphenyl (CBP) has shown excellent properties as a phosphorescent host material.

However, existing materials have an advantage in terms of light emission characteristics, but their thermal stability is lowered due to their low glass transition temperature, so that they are not satisfactory in terms of lifetime in OLED devices. Therefore, development of materials with higher performance is required.

An object of the present invention is to provide a novel organic compound capable of improving the bonding force between holes and electrons while having excellent thermal stability due to a high glass transition temperature.

It is another object of the present invention to provide an organic electroluminescent device including the novel organic compound and having improved driving voltage, luminous efficiency, and the like.
