Abstract

Disclosed (or Provided) are a heterocyclic compound and an organic light emitting device including the same.

First claim

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

wherein, in Chemical Formula 1,
L1 to L3 are the same as or different from each other, and are each independently a direct bond; a substituted or unsubstituted C6 to C60 arylene group; or a substituted or unsubstituted C2 to C60 heteroarylene group,
R1 to R3 are the same as or different from each other, and are each independently hydrogen; deuterium; a substituted or unsubstituted amine group; a substituted or unsubstituted C6 to C60 aryl group; a substituted or unsubstituted C2 to C60 heteroaryl group; or —P(═O)RR′,
at least one of R1 to R3 is a substituted or unsubstituted amine group, and another one of R1 to R3 is a substituted or unsubstituted C2 to C60 heteroaryl group; or —P(═O)RR′,
R and R′ are the same as or different from each other, and are each independently hydrogen; deuterium; —CN; a substituted or unsubstituted C6 to C60 aryl group; or a substituted or unsubstituted C2 to C60 heteroaryl group,
Ra, Rb and Rc are the same as or different from each other, and are each independently hydrogen; deuterium; a halogen group; —CN; a substituted or unsubstituted C1 to C60 alkyl group; a substituted or unsubstituted C6 to C60 aryl group; or a substituted or unsubstituted C2 to C60 heteroaryl group,
a, b and c are an integer from 0 to 4, and when a, b and c are 2 or higher, substituents in the parenthesis are the same as or different from each other,
p is an integer from 0 to 4, and when p is 2 or higher, substituents in the parenthesis are the same as or different from each other,
q is an integer from 0 to 3, and when q is 2 or higher, substituents in the parenthesis are the same as or different from each other, and
r is an integer from 0 to 5, and when r is 2 or higher, substituents in the parenthesis are the same as or different from each other.

2 . The heterocyclic compound of claim 1 , wherein Chemical Formula 1 is represented by any one of the following Chemical Formulae 1-1 to 1-6:

in Chemical Formulae 1-1 to 1-6,
L1 to L3, R1 to R3, Ra, Rb, Rc, a, b, c, p, q and r are the same as the definitions in Chemical Formula 1,
R11, R12, R21, R22, R31 and R32 are the same as or different from each other, and are each independently a substituted or unsubstituted C6 to C60 aryl group; or a substituted or unsubstituted C2 to C60 heteroaryl group,
p1 and p2 are each an integer from 0 to 5, and p1 and p2 are 2 or higher, substituents in the parenthesis are the same as or different from each other,
q1 and q2 are each an integer from 0 to 4, and when q1 and q2 are 2 or higher, substituents in the parenthesis are the same as or different from each other, and
r1 and r2 are each an integer from 0 to 6, and when r1 and r2 are 2 or higher, substituents in the parenthesis are the same as or different from each other.

3 . The heterocyclic compound of claim 1 , wherein R1 to R3 are the same as or different from each other, and are each independently hydrogen; deuterium; an amine group which is unsubstituted or substituted with a substituted or unsubstituted C6 to C40 aryl group or a substituted or unsubstituted C2 to C40 heteroaryl group; a substituted or unsubstituted C2 to C40 heteroaryl group; or —P(═O)RR′, and
any one of R1 to R3 is an amine group which is unsubstituted or substituted with a substituted or unsubstituted C6 to C40 aryl group or a substituted or unsubstituted C2 to C40 heteroaryl group, and another one of R1 to R3 is a substituted or unsubstituted C2 to C40 heteroaryl group; or —P(═O)RR′.

4 . The heterocyclic compound of claim 2 , wherein R11, R12, R21, R22, R31 and R32 are the same as or different from each other, and are each independently a substituted or unsubstituted C6 to C20 aryl group; or a substituted or unsubstituted C2 to C20 heteroaryl group.

5 . The heterocyclic compound of claim 1 , wherein L1 to L3 are the same as or different from each other, and are each independently a direct bond; or a substituted or unsubstituted C6 to C20 arylene group.

6 . The heterocyclic compound of claim 1 , wherein Ra, Rb and Rc are the same as or different from each other, and are each independently hydrogen; or deuterium.

7 . The heterocyclic compound of claim 1 , wherein a deuterium content of the heterocyclic compound of Chemical Formula 1 is 0%, or 30% to 100%.

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