Abstract

The present invention provides a novel compound capable of improving light emitting efficiency, stability, and lifespan of the element, an organic element using the same, and an electric device for the same.

First claim

1 . A compound represented by Formula 1 below:

wherein,
Ar 1 and Ar 2 are independently selected from the group consisting of a C 6 -C 60 aryl group, a fluorenyl group, a C 2 -C 60 heterocyclic group containing at least one heteroatom selected from the group consisting of O, N, S, Si, and P, a C 1 -C 50 alkyl group, a C 2 -C 20 alkenyl group, a C 1 -C 30 alkoxy group, a C 6 -C 60 aryloxy group, C 3 -C 60 cycloalkyl group, and —N(R′)(R″),
wherein, R′ and R″ are independently selected from the group consisting of a C 6 -C 60 aryl group, a fluorenyl group, and a C 2 -C 60 heterocyclic group containing at least one heteroatom selected from the group consisting of O, N, S, Si, and P,
L 1 and L 2 are independently selected from the group consisting of a C 6 -C 60 arylene group, a fluorenylene group, a C 2 -C 60 heterocyclic group containing at least one heteroatom selected from the group consisting of O, N, S, Si, and P, a fused ring group of a C 3 -C 60 aliphatic ring and a C 6 -C 60 aromatic ring, and a bivalent aliphatic hydro carbon, with the proviso that, the arylene group, the fluorenylene group, the heterocyclic group, the fused ring group and the aliphatic hydrocarbon group are optionally substituted by one or more substituents selected from the group consisting of a nitro group, a nitrile group, halogen group, a C 1 -C 20 alkyl group, a C 6 -C 20 aryl group, a C 2 -C 20 heterocyclic group, a C 1 -C 20 alkoxy group, and amino group, and with the proviso that the aryl group, fluorenyl group, heterocyclic group, alkyl group, cycloalkyl group, alkenyl group and aryloxy group are optionally substituted by one or more substituents selected from the group consisting of deuterium, halogen, a silane group, a siloxane group, a boron group, a germanium group, a cyano group, a nitro group, a C 1 -C 20 alkylthio group, a C 1 -C 20 alkoxy group, a C 1 -C 20 alkyl group, a C 2 -C 20 alkenyl group, a C 2 -C 20 alkynyl group, a C 6 -C 20 aryl group, a C 6 -C 20 aryl group substituted by deuterium, a C 2 -C 20 heterocyclic group, a C 3 -C 20 cycloalkyl group, a C 7 -C 20 arylalkyl group, and a C 8 -C 20 arylalkenyl group.

2 . The compound as claimed in claim 1 , wherein the compound is represented by one of Formulas below:

wherein,
Ar 1 , L 1 and L 2 are as defined in claim 1 ,
Ar 3 is selected from the group consisting of a C 6 -C 60 aryl group, a C 2 -C 20 alkenyl group, a C 2 -C 60 heterocyclic group containing at least one heteroatom selected from the group consisting of O, N, S, Si, and P, a C 1 -C 50 alkyl group, and a fluorenyl group,
X 1 to X 5 and Z 1 to Z 4 are independently CR 1 or N, and,
R 1 is selected from the group consisting of hydrogen, a C 6 -C 60 aryl group, a fluorenyl group, C 2 -C 60 heterocyclic group containing at least one heteroatom selected from the group consisting of O, N, S, Si, and P.

3 . The compound as claimed in claim 1 , being any one of the compounds below:

4 . An organic electric element comprising a first electrode, a second electrode, and an organic material layer disposed between the first electrode and the second electrode, wherein the organic material layer comprises the compound of claim 1 .

5 . The organic electric element as claimed in claim 4 , wherein the organic material layer is formed by a soluble process.

6 . The organic electric element as claimed in claim 4 , wherein the organic material layer comprises at least one of a light emitting layer, a hole injection layer, a hole transport layer, an emission-auxiliary layer, an electron injection layer and an electron transport layer.

7 . The organic electric element as claimed in claim 6 , wherein the light emitting layer comprises the compound.

8 . An electronic device comprising a display device, which comprises the organic electric element as claimed in claim 4 , and a control unit for driving the display device.

9 . The electronic device as claimed in claim 8 , wherein the organic electric element comprises at least one of an organic light emitting diode, an organic solar cell, an organic photo conductor, an organic transistor, and an element for monochromatic or white illumination.
