Abstract
The present invention provides an organic compound represented by the following formula 1 and an organic electroluminescent device including the organic compound: general formula 1
Description
Technical Field
The invention relates to the field of display screens, in particular to an organic compound used in the manufacture of an organic electroluminescent device of a display screen and an organic electroluminescent device containing the compound.
Background
So far, most of the flat panel displays are liquid crystal displays, but there has been a continuous active effort to develop new flat panel displays which are more economical, have more superior performance, and are different from the liquid crystal displays all over the world. Recently, organic electroluminescent devices, which have attracted attention as next-generation flat panel displays, have advantages such as low driving voltage, high response speed, and wide viewing angle, as compared to liquid crystal displays.
According to the structure of the organic electroluminescent device, the organic electroluminescent device is composed of a substrate, an anode, a hole injection layer for receiving holes from the anode, a hole transport layer for transporting holes, an electron blocking layer for blocking electrons from entering the hole transport layer from the light emitting layer, a light emitting layer for emitting light by combining holes and electrons, a hole blocking layer for blocking holes from entering the electron transport layer from the light emitting layer, an electron transport layer for receiving electrons from the cathode and transporting the electrons to the light emitting layer, an electron injection layer for receiving electrons from the cathode, and a cathode. In the case of using a polymer, generally, one polymer may simultaneously perform the roles of the hole transport layer and the emission layer as well as the electron transport layer. The organic thin film layer between the two electrodes can be formed by a vacuum deposition method, a spin coating method, ink jet printing, laser hot stamping, or the like. In order to stabilize the interface between the electrode and the organic material, and in the case of using an organic material, since the difference in the moving speed between holes and electrons is large, the organic electroluminescent device is fabricated in a multi-layer thin film structure, and thus, the holes and the electrons are efficiently transferred to the light-emitting layer by using an appropriate hole transport layer and an appropriate electron transport layer, and the density of the holes and the electrons is equalized, thereby improving the light-emitting efficiency.
The driving principle of the organic electroluminescent device is as follows: when a voltage is applied between the anode and the cathode, holes injected from the anode are transferred to the light-emitting layer through the hole injection layer and the hole transport layer. At the same time, electrons are injected from the cathode into the light-emitting layer via the electron injection layer and the electron transport layer, and recombine with carriers in the light-emitting layer to form excitons. The excitons change to the ground state in this state, and thereby fluorescent molecules of the light-emitting layer emit light to form an image. At this time, the excited state returns to the ground state through the singlet excited state, and the emitted light is called "fluorescence"; the light emitted is called "phosphorescence" by returning to the ground state through the triplet excited state. The probability of returning to the base state by the singlet excited state is 25% (the probability of returning to the triplet excited state is 75%), and therefore, the light emission efficiency is limited. When phosphorescence is used, 75% of the triplet state and 25% of the singlet excited state can be used for light emission, and thus, theoretically, the internal quantum efficiency can reach 100%.
The biggest problems of such organic electroluminescent devices are lifetime and luminous efficiency, which must be solved as the display screen becomes larger in area.
In particular, blue color, although substances such as ADN and DPVBi can be used as host substances and substances such as aromatic amine compounds, phthalocyanine copper compounds, carbazole derivatives, perylene derivatives, coumarin derivatives, and pyrene derivatives can be used as dopants, it is difficult to obtain deep blue color and there is a problem that the lifetime becomes shorter as the wavelength becomes shorter.
Therefore, in the full color display that displays natural colors, development of a material that can emit deep blue light with a long service life and another organic material that is suitable for the energy level of such a blue material is strongly demanded.
