Abstract

Provided are an organic electronic element comprising a compound capable of improving luminous efficiency, stability and lifetime of an organic electronic device, in an emitting auxiliary layer or electron blocking layer formed between an emitting layer and a hole transport layer of the element, and an electronic device comprising the same.

First claim

What is claimed is:

1. An organic electronic element comprising an anode; a cathode; an organic material layer formed between the anode and the cathode, wherein the organic material layer includes an emitting layer, an hole transport layer formed between the anode and the emitting layer; and an emitting auxiliary layer or an electron blocking layer (EBL) formed between the emitting layer and the hole transport layer; wherein the emitting auxiliary layer or the electron blocking layer comprises a compound represented by Formula (32):

wherein:
R 20 , R 21 , R 22 , R 23 , R 24 , and R 25 are each independently selected from the group consisting of hydrogen; deuterium; halogen; a C 6 -C 30 aryl group; a fluorenyl group; a C 2 -C 30 heterocyclic group including at least one heteroatom of O, N, S, Si or P; a fused ring group of a C 3 -C 30 aliphatic ring and a C 6 -C 30 aromatic ring; a C 1 -C 30 alkyl group; a C 2 -C 20 alkenyl group; a C 2 -C 20 alkynyl group; a C 1 -C 30 alkoxyl group; and a C 6 -C 30 aryloxy group, or a plurality of R 20 , a plurality of R 23 , a plurality of R 24 , and/or a plurality of R 25 may be bonded to each other to form an aromatic ring or a heteroaromatic ring,
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,
L 20 and L 21 are each independently a single bond,
Ar 20 is a C 6 -C 24 aryl group,
X 20 is CR′R″, wherein R′ and R″ are each a C 1 -C 30 alkyl group.

2. The organic electronic element according to claim 1 , wherein the compound represented by Formula (32) is Formula (38):

wherein R 20 , R 21 , R 22 , R 23 , R 24 , R 25 , L 20 , L 21 , Ar 20 and X 20 , v w x, y and z are the same as defined in claim 1 .

3. The organic electronic element according to claim 1 , wherein the compound represented by Formula (32) is Formula (39):

wherein R 20 , R 21 , R 22 , R 23 , R 24 , R 25 , L 20 , L 21 , Ar 20 and X 20 , u, v, w, x, y and z are the same as defined in claim 1 .
