Abstract

Provided are a compound of Formula 1 and an organic electric element comprising a first electrode, a second electrode, and an organic material layer formed between the first electrode and the second electrode, and electronic device comprising the organic electric element, wherein the luminous efficiency and life span can be improved and the driving voltage of the organic electronic device can be lowered by comprising the compound represented by Formula 1 in the organic material layer.

First claim

The invention claimed is:

1. A compound of Formula 1:

wherein,
“A” and “B” are each formula 1-1, with the proviso that the case where Ar 1 to Ar a are phenyl and L 1 is m-phenylene is excluded,
Ar 1 to Ar 3 are each 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 fused ring formed by a C 6 -C 60 aromatic ring and a C 3 -C 60 aliphatic ring; -L′-N(R a )(R b ); and the combination thereof,
L 1 is selected from the group consisting of a single bond; a C 6 -C 60 arylene group; a fluorenylene group; a fused ring formed by a C 6 -C 60 aromatic ring and a C 3 -C 60 aliphatic ring; a C 2 -C 60 heterocyclic group containing at least one heteroatom selected from the group consisting of O, N, S, Si, and P; and the combination thereof,
R 1 to R 4 is i) selected from the group consisting of hydrogen; deuterium; halogen; 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 fused ring formed by a C 6 -C 60 aromatic ring and a C 3 -C 60 aliphatic ring; a C 1 -C 50 alkyl group; a C 2 -C 20 alkenyl group; a C 2 -C 20 alkynyl group; a C 1 -C 30 alkoxy group; a C 6 -C 30 aryloxy group; -L′-N(R a )(R b ); and a combination thereof, or ii) neighboring groups of R 1 s to R 4 s may be linked to each other to form a ring together with a benzene ring to which they are bonded, and wherein R 1 s to R 4 s not forming a ring are each the same as defined in the above i),
L′ is selected from the group consisting of a single bond; a C 6 -C 60 arylene group; a fluorenylene group; a fused ring formed by a C 6 -C 60 aromatic ring and a C 3 -C 60 aliphatic ring; 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,
R a and R b are each independently selected from the group consisting of a C 6 -C 60 aryl group; a fluorenyl group; a fused ring formed by a C 6 -C 60 aromatic ring and a C 3 -C 60 aliphatic ring; 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, and
the above aryl group, fluorenyl group, heterocyclic group, fused ring, alkyl group, alkenyl group, alkynyl group, alkoxy group, aryloxy group, arylene group and fluorenylene group may be each substituted with 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 with deuterium; a fluorenyl group; a C 2 -C 20 heterocyclic group containing at least one heteroatom selected from the group consisting of O, N, S, Si and P; 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 of claim 1 , wherein Formula 1 is any one of the compounds below:

3. 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 .

4. The organic electric element of claim 3 , wherein at least one of a hole injection layer, a hole transport layer, an emission-auxiliary layer and an light emitting layer of the organic material layer comprises one kind or two or more kinds of compounds represented by Formula 1.

5. The organic electric element of claim 3 , wherein the organic electric element further including at least one layer to improve luminous efficiency which is formed on at least one of the sides the first and second electrodes, which is opposite to the organic material layer.

6. The organic electric element of claim 3 , wherein the organic material layer is formed by any one of the processes of spin coating, nozzle printing, inkjet printing, slot coating, dip coating and roll-to-roll.

7. An electronic device comprising:
a display device comprising the organic electric element of claim 1 ; and
