Definitions
- the present invention relates to a novel boron compound that can be used in an organic light emitting device, and more particularly, it can be used as a dopant material in a light emitting layer in an organic light emitting device, thereby improving device characteristics such as high luminous efficiency and low voltage driving. It relates to a novel boron compound that can be implemented and an organic light emitting device including the boron compound.
- OLED organic light emitting diode
- the organic light emitting phenomenon refers to a phenomenon in which electric energy is converted into light energy using an organic material.
- An organic light emitting device using an organic light emitting phenomenon generally has a structure including an anode and a cathode and an organic material layer therebetween.
- the organic layer is often formed of a multi-layered structure composed of different materials in order to increase the efficiency and stability of the organic light emitting device, for example, a hole injection layer, a hole transport layer, a light emitting layer, an electron transport layer, an electron injection layer, and the like.
- organic light emitting device when a voltage is applied between the two electrodes, holes are injected into the organic material layer from the anode and electrons from the cathode are injected into the organic material layer. When the injected holes and electrons meet, excitons are formed, and the excitons When it falls back to the ground state, it lights up.
- Such an organic light emitting device is known to have characteristics such as self-luminescence, high luminance, high efficiency, low driving voltage, wide viewing angle, high contrast, and high-speed response.
- the material used as the organic layer in the organic light emitting device may be classified into a light emitting material and a charge transport material, such as a hole injection material, a hole transport material, an electron transport material, an electron injection material, etc., depending on the function, and if necessary, the electron blocking layer Alternatively, a hole blocking layer may be added.
- the light emitting material can be classified into a high molecular type and a low molecular type according to molecular weight, and can be classified into a fluorescent material derived from a singlet excited state of an electron and a phosphorescent material derived from a triplet excited state of an electron according to a light emitting mechanism. .
- a host-dopant system can be used as a luminescent material to increase the luminous efficiency through transition.
- the principle is that when a small amount of a dopant having a smaller energy band gap than that of a host forming the emission layer is mixed in the emission layer, excitons generated in the emission layer are transported to the dopant to emit light with high efficiency. At this time, since the wavelength of the host moves to the wavelength band of the dopant, light having a desired wavelength may be obtained according to the type of the dopant used.
- Korean Patent Application Laid-Open No. 10-2016-0119683 discloses a plurality of aromatic rings with boron atoms and oxygen atoms.
- a polycyclic aromatic compound connected to and an organic light emitting device including the same are disclosed, and
- International Patent Publication No. 2017-188111 discloses a compound having a structure in which a plurality of condensed aromatic rings are connected by a boron atom and nitrogen.
- An organic light emitting device using an anthracene derivative as a host and used as a dopant in the light emitting layer is described.
- the first technical task to be achieved by the present invention is to provide a boron compound having a novel structure that can be used as a dopant material for a light emitting layer in an organic light emitting device.
- the second technical task to be achieved by the present invention is to apply the boron compound to a dopant material in an organic light emitting device, thereby providing an organic light emitting diode (OLED) having excellent device characteristics such as high luminous efficiency and low voltage driving.
