ORGANIC COMPOUND AND LIGHT EMITTING DIODE AND ORGANIC LIGHT EMITTING DIODE DISPLAY DEVICE USING THE SAME

The present invention relates to an organic compound in which at least one amine group is directly or indirectly linked to an imidazopyridine core. The organic compound of the present invention has an imidazopyridine core and an amine group, and thus is excellent in hole transporting properties and hole injection properties. Therefore, when the organic compound of the present invention is used for a hole layer, an electron blocking layer and/or a charge generation layer of a light emitting device, the device can be driven at a low voltage. A sufficient current density can be ensured even at the low voltage to realize good luminous efficiency, so that stress on the compound forming the light emitting device is reduced by high voltage driving.(110) First electrode(120) Second electrodeCOPYRIGHT KIPO 2018

ORGANIC COMPOUND AND ORGANIC LIGHT EMITTING DIODE AND ORGANIC LIGHT EMITTING DIODE DISPLAY DEVICE USING THE SAME

The present invention relates to an organic compound in which two amine groups are connected by biphenylene, and one or two substituents having a silyl group is or are connected to nitrogen atoms forming the amine groups. According to the present invention, the organic compound is excellent in hole injection properties, hole transport properties and/or electron blocking properties by comprising the amine groups. Further, the organic compound has improved light emitting efficiency compared to the case in which the substituent which does not have the silyl group, or has two or more silyl groups is connected to the nitrogen atoms. Therefore, when the organic compound of the present invention is applied to a hole layer, an electron blocking layer and/or a charge generation layer of an organic light emitting diode, light emitting efficiency is improved, and current density can be reduced. Accordingly, light emitting efficiency of the organic light emitting diode, to which the organic compound of the present invention is applied, can be greatly improved.COPYRIGHT KIPO 2018

Method for producting aromatic amino compound

A method for producing aromatic amino compound (V): by synthesizing intermediate compound (IV): by the reaction of compound (I): H2N—R1 with a mixture of halogenated aryl compounds (II): Ar1-X and (III): Ar2-X in the presence of a noble metal catalyst, followed by eliminating the substituent R1 from the nitrogen atom in compound (IV) under an acidic condition or an alkaline condition or by addition of a reducing agent or an oxidizing agent. (R1: a substituent having 2 to 50 carbon atoms; Ar1 and Ar2: a substituted or unsubstituted hydrocarbon group or heterocyclic group having 6 to 50 carbon atoms and the same with or different from each other; and X: a halogen group). The aromatic amino compound useful as the charge transporting material can be produced efficiently at a great yield without using highly toxic raw materials.
