Abstract

Disclosed are a novel-structural compound including a 5-membered heterocycle, an organic electronic device using the same, and a terminal thereof.

First claim

What is claimed is:

1 . A compound represented by the following formula:

wherein, R 1 through R 10 each are independently selected from the group consisting of a hydrogen atom, a halogen atom, a cyano group, an alkoxy group, a thiol group, a substituted or unsubstituted alkyl group having 1 to 50 carbon atoms, a substituted or unsubstituted alkoxy group having 1 to 50 carbon atoms, a substituted or unsubstituted alkenyl group having 2 to 50 carbon atoms, a substituted or unsubstituted arylene group having 6 to 60 carbon atoms, a substituted or unsubstituted aryl group having 6 to 60 carbon atoms, a substituted or unsubstituted aryloxy group having 6 to 60 carbon atoms, a substituted or unsubstituted C 1 -C 50 alkyl group having at least one of sulfur (S), nitrogen (N), oxygen (O), phosphorous (P) and silicon (Si), a substituted or unsubstituted C 5 -C 60 heteroaryl group having at least one heteroatom selected from the group consisting of sulfur (S), nitrogen (N), oxygen (O), phosphorous (P) and silicon (Si), and a substituted or unsubstituted C 5 -C 60 heteroaryloxy group having at least one of sulfur, nitrogen, oxygen, phosphorous and silicon, wherein R 1 through R 10 optionally form a substituted or unsubstituted, saturated or unsaturated ring together with an adjacent group;
X is at least one selected from sulfur, oxygen or silicon,
Y is selected from the group consisting of a hydrogen atom, a halogen atom, a cyano group, an alkoxy group, a thiol group, a substituted or unsubstituted alkyl group having 1 to 50 carbon atoms, a substituted or unsubstituted alkenyl group having 2 to 50 carbon atoms, a substituted or unsubstituted arylene group having 6 to 60 carbon atoms, a substituted or unsubstituted aryl group having 6 to 60 carbon atoms, a substituted or unsubstituted aryloxy group having 6 to 60 carbon atoms, a substituted or unsubstituted C 1 -C 50 alkyl group having at least one of sulfur, nitrogen, oxygen, phosphorous and silicon, a substituted or unsubstituted C 5 -C 60 heteroaryl group having at least one heteroatom selected from the group consisting of sulfur, nitrogen, oxygen, phosphorous and silicon, and a substituted or unsubstituted C 5 -C 60 heteroaryloxy group having at least one of sulfur, nitrogen, oxygen, phosphorous and silicon, with the proviso that when Y is a substituted aryl or arylene group having 6 to 60 carbon atoms, Y is not substituted with a pyrenyl group or a substituted pyrenyl group, and
n is an integer from 1 to 3,
wherein a compound represented by the formula wherein R 1 to R 10 are each hydrogen, X is S, Y is a substituted or unsubstituted C 5 -C 60 heteroaryl group containing nitrogen and n is 1, is excluded.

2 . The compound of claim 1 , wherein R 1 through R 10 each optionally form a substituted or unsubstituted saturated or unsaturated ring together with an adjacent group.

3 . The compound of claim 1 selected from the group consisting of the following compounds:

4 . An organic electronic device comprising one or more organic material layers comprising the compound as claimed in claim 1 .

5 . The organic electronic device as claimed in claim 4 , wherein the organic material layers are formed by a soluble process of the compound.

6 . The organic electronic device as claimed in claim 4 , wherein the organic electronic device is an organic light emitting diode in which a first electrode, said one or more organic material layers, and a second electrode are sequentially layered.

7 . The organic electronic device as claimed in claim 6 , wherein the organic material layers comprise any one of a hole injection layer, a hole transport layer, a light emitting layer, and electron transport layer, and an electron injection layer.

8 . The organic electronic device as claimed in claim 6 , wherein the organic material layers comprise a light emitting layer, and in the light emitting layer, the compound is used as a host or dopant material.

9 . A terminal comprising a display device and a control part for driving the display device, the display device comprising the organic electronic device as claimed in claim 6 .

10 . The terminal as claimed in claim 9 , wherein the organic electronic device is any one of an organic light emitting diode (OLED), an organic solar cell, an organic photo conductor (OPC) drum, and an organic transistor (organic TFT).

11 . The compound as claimed in claim 1 , wherein Y is a substituted or unsubstituted aryl group having 6 to 60 carbon atoms.

12 . The compound of claim 11 , wherein Y is substituted with a heteroaryl group having 6 to 60 carbon atoms.

13 . The compound as claimed in claim 1 , wherein R 1 to R 10 each are hydrogen.
