Abstract

Provided is a compound of Formula 1:

and an organic light emitting device including the same.

First claim

The invention claimed is:

1. A compound of Formula 1:

wherein in Formula 1:
X1 and X2 are the same as or different from each other, and are each independently —O—, —S—, —C(R7R8)-, or —N(R9);
at least two of R1 to R4 are the same as or different from each other, and are each independently a group of the following Formula A;
groups which are not the following Formula A among R1 to R4 are the same as or different from each other, and are each independently hydrogen, deuterium, a substituted or unsubstituted alkyl group, a substituted or unsubstituted aryl group, or a substituted or unsubstituted heteroaryl group;
R5 and R6 are the same as or different from each other, and are each independently hydrogen, deuterium, a substituted or unsubstituted alkyl group, a substituted or unsubstituted aryl group, or a substituted or unsubstituted heteroaryl group, or adjacent groups are bonded to each other to form a substituted or unsubstituted ring;
R7 to R9 are the same as or different from each other, and are each independently a substituted or unsubstituted alkyl group, a substituted or unsubstituted aryl group, or a substituted or unsubstituted heteroaryl group;
a and b are each an integer from 1 to 4;
when a and b are each 2 or more, two or more structures in the parenthesis are the same as or different from each other:

wherein in Formula A:
L1 is a direct bond, a substituted or unsubstituted arylene group, or a substituted or unsubstituted heteroarylene group;
Ar1 and Ar2 are the same as or different from each other, and are each independently a substituted or unsubstituted aryl group, or a substituted or unsubstituted heteroaryl group, or are optionally bonded to each other to form a substituted or unsubstituted ring;
m is an integer from 1 to 5;
when m is 2 or more, two or more L1's are the same as or different from each other; and

is a moiety bonded to Formula 1.

2. The compound of claim 1 , wherein Formula 1 is any one of the following Formulae 1-1 to 1-3:

wherein in Formulae 1-1 to 1-3:
the definitions of X1, X2, and R1 to R4 are the same as those defined in Formula 1;
R5, R6, R51, and R61 are the same as or different from each other, and are each independently hydrogen, deuterium, a substituted or unsubstituted alkyl group, a substituted or unsubstituted aryl group, or a substituted or unsubstituted heteroaryl group;
a1 and b1 are each 1 or 2;
r51 and r61 are each an integer from 1 to 4;
when a1 and b1 are each 2, the structures in the parenthesis are the same as or different from each other; and
when r51 and r61 are each 2 or more, two or more structures in the parenthesis are the same as or different from each other.

3. The compound of claim 1 , wherein Formula 1 is any one of the following Formulae 1-4 to 1-7:

wherein in Formulae 1-4 to 1-7:
the definitions of X1, X2, R5, R6, a, and b are the same as those defined in Formula 1;
R1 and R2 are the same as or different from each other, and are each independently a group of Formula A; and
R3 and R4 are the same as or different from each other, and are each independently hydrogen, deuterium, a substituted or unsubstituted alkyl group, a substituted or unsubstituted aryl group, or a substituted or unsubstituted heteroaryl group.

4. The compound of claim 1 , wherein Formula 1 is any one of the following Formulae 1-9 to 1-12:

wherein in Formulae 1-9 to 1-12:
the definitions of X1, X2, R5, R6, a, and b are the same as those defined in Formula
the definitions of L1, m, Ar1, and Ar2 are the same as those defined in Formula A;
R3 and R4 are the same as or different from each other, and are each independently hydrogen, deuterium, a substituted or unsubstituted alkyl group, a substituted or unsubstituted aryl group, or a substituted or unsubstituted heteroaryl group;
L11 is a direct bond, a substituted or unsubstituted arylene group, or a substituted or unsubstituted heteroarylene group;
Ar11 and Ar12 are the same as or different from each other, and are each independently a substituted or unsubstituted aryl group, or a substituted or unsubstituted heteroaryl group, or are optionally bonded to each other to form a substituted or unsubstituted ring;
m1 is an integer from 1 to 5; and
when m1 is 2 or more, two or more L11's are the same as or different from each other.

5. The compound of claim 1 , wherein L1 is a direct bond or an arylene group.

6. The compound of claim 1 , wherein Ar1 and Ar2 are the same as or different from each other, and are each independently an aryl group which is unsubstituted or substituted with a halogen group, an alkyl group, or an aryl group; or a heteroaryl group which is unsubstituted or substituted with an alkyl group or an aryl group.

7. The compound of claim 1 , wherein the compound of Formula 1 is selected from among the following compounds:
