Abstract

The present specification relates to a heterocyclic compound represented by Chemical Formula 1, and an organic light emitting device including the same.

First claim

1 . A heterocyclic compound represented by the following Chemical Formula 1:

in Chemical Formula 1,
one of X and X′ is O; S; or NR 21 , and the other one is a direct bond;
one of Y and Y′ is O; S; or NR 22 , and the other one is a direct bond;
A and B are each independently a C6 to C60 aryl ring, and at least one thereof is a C10 to C60 aryl ring;
R 1 is selected from the group consisting of a halogen group; a cyano group; a substituted or unsubstituted alkyl group; a substituted or unsubstituted alkenyl group; a substituted or unsubstituted alkynyl group; a substituted or unsubstituted alkoxy group; a substituted or unsubstituted cycloalkyl group; a substituted or unsubstituted heterocycloalkyl group; a substituted or unsubstituted aryl group; a substituted or unsubstituted heteroaryl group; a substituted or unsubstituted phosphine oxide group; and a substituted or unsubstituted amine group, or two or more groups adjacent to each other bond to each other to form a substituted or unsubstituted aliphatic or aromatic hydrocarbon ring or heteroring;
R 21 and R 22 are each independently a substituted or unsubstituted aryl group; or a substituted or unsubstituted heteroaryl group;
r1 is an integer of 1 to 12; and
when r1 is an integer of 2 or greater, substituents in the parentheses are the same as or different from each other.

2 . The heterocyclic compound of claim 1 , wherein Chemical Formula 1 is represented by the following Chemical Formula 2 or Chemical Formula 3:

in Chemical Formulae 2 and 3,
X, X′, Y, Y′, R 1 and r1 have the same definitions as in Chemical Formula 1;
A1 is benzene;
A2 is naphthalene;
C is a C10 to C60 aryl ring; and
D is a C6 to C60 aryl ring.

3 . The heterocyclic compound of claim 1 , wherein Chemical Formula 1 is represented by any one of the following Chemical Formula 4 to Chemical Formula 10:

in Chemical Formulae 4 to 10,
X, X′, Y and Y′ have the same definitions as in Chemical Formula 1;
R 2 to R 7 are each independently selected from the group consisting of hydrogen; a halogen group; a cyano group; a substituted or unsubstituted alkyl group; a substituted or unsubstituted alkenyl group; a substituted or unsubstituted alkynyl group; a substituted or unsubstituted alkoxy group; a substituted or unsubstituted cycloalkyl group; a substituted or unsubstituted heterocycloalkyl group; a substituted or unsubstituted aryl group; a substituted or unsubstituted heteroaryl group; a substituted or unsubstituted phosphine oxide group; and a substituted or unsubstituted amine group, or two or more groups adjacent to each other bond to each other to form a substituted or unsubstituted aliphatic or aromatic hydrocarbon ring or heteroring, and at least one of R 2 and R 3 , at least one of R 4 and R 5 and at least one of R 6 and R 7 are a substituted or unsubstituted aryl group; a substituted or unsubstituted heteroaryl group; or a substituted or unsubstituted amine group;
r2, r4, r6 and r7 are each an integer of 1 to 4;
r3 and r5 are each an integer of 1 to 6; and
when r2 to r7 are each an integer of 2 or greater, substituents in the parentheses are the same as or different from each other.

4 . The heterocyclic compound of claim 1 , wherein one of A and B is benzene, and the other one is naphthalene.

5 . The heterocyclic compound of claim 1 , wherein R 21 and R 22 are selected from among the following structural formulae:

in the structural formulae,
R 10 to R 15 are each independently hydrogen; a substituted or unsubstituted aryl group; or a substituted or unsubstituted heteroaryl group;
r11 is 1 or 2;
r10 and r12 to r14 are each independently an integer of 1 to 5;
r15 is an integer of 1 to 7; and
when r10 to r15 are each an integer of 2 or greater, substituents in the parentheses are the same as or different from each other.

6 . The heterocyclic compound claim 1 , wherein R 1 is a substituted or unsubstituted aryl group; a substituted or unsubstituted heteroaryl group; or a substituted or unsubstituted amine group.

7 . The heterocyclic compound claim 1 , wherein Chemical Formula 1 is represented by any one of the following compounds:
