Abstract

Provided are a compound of Formula 32 capable of improving luminous efficiency, stability and lifetime of an organic electric element employing the same, the organic electric element and an electronic device thereof.

First claim

What is claimed is:

1 . A compound of Formula (32):

wherein:
1) R 20 , R 21 , R 22 , R 23 , R 24 and R 25 are each independently selected from the group consisting of hydrogen deuterium, a C 6 -C 30 aryl group and a C 1 -C 20 alkyl group, and a plurality of R 20 , a plurality of R 21 , a plurality of R 22 , a plurality of R 23 , and a plurality of R 24 are not bonded to each other to form a ring,
2) v is an integer of 0 to 3, u, w, x and y are each independently an integer of 0 to 4, z is an integer of 0 to 5,
3) L 20 and L 21 are each a single bond,
4) Ar 20 is a C 6 -C 30 aryl group,
5) X 20 is CR′R″, and
6) R′ and R″ are each independently selected from the group of a C 1 -C 30 alkyl group; a C 6 -C 30 aryl group; and R′ and R″ may be bonded to each other to form a spiro,
wherein the aryl group and alkyl group may be each substituted with one or more substituent(s) selected from the group consisting of deuterium, halogen, a C 1 -C 20 alkyl group, a C 2 -C 20 alkenyl 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, and a C 3 -C 20 cycloalkyl group, and wherein the substituent(s) may be substituted with one or more deuterium.

2 . The compound of claim 1 , wherein Formula 32 is represented by Formula 38 or Formula 39:

3 . The compound of claim 1 , wherein u+v+w+x+y+z≥1 and at least one of R 20 to R 25 is an alkyl group or an aryl group.

4 . The compound of claim 1 , wherein Ar 20 is represented by any of Formulas Ar-1 to Ar-8:

wherein:
1) R 30 , R 31 , R 32 , R 33 , R 34 , R 35 and R 36 are each independently selected from the group consisting of hydrogen, deuterium, a C 1 -C 30 alkyl group, and a C 6 -C 20 aryl group, and a plurality of R 30 , a plurality of R 31 , a plurality of R 32 , a plurality of R 33 , a plurality of R 34 , a plurality of R 35 , a plurality of R 36 , a plurality of R 37 , or a plurality of R 38 , each in the plurality being the same as or different from each other, can be bonded to each other to form an aromatic or a heteroaromatic ring, and
2) aa is an integer of 0 to 5; ab is an integer of 0 to 4; ac is an integer of 0 to 7; ad is an integer of 0 to 9; ae, af and ai are each independently an integer of 0 to 4;
ag and ah are each independently an integer of 0 to 3.

5 . The compound of claim 1 , wherein the compound of Formula 32 is any of the following compounds.

6 . An organic electronic element comprising an anode; a cathode; and an organic layer formed between the anode and the cathode, wherein the organic layer comprises a compound of Formula 32 of claim 1 .

7 . The organic electronic element of claim 6 , wherein the organic layer comprises at least 2 or more stacks of layers.

8 . The organic electronic element of claim 7 , wherein a charge generation region is included between the 2 or more stacks.

9 . The organic electronic element of claim 8 , wherein the charge generation region comprises a n-type charge generation layer and a p-type charge generation layer.

10 . The organic electronic element of claim 9 , wherein the p-type charge generation layer comprises a compound of Formula 32.
