Abstract
The present specification relates to a heterocyclic compound represented by Chemical Formula 1, and an organic light emitting device comprising the same.
Claims14
A heterocyclic compound represented by the following Chemical Formula 1:
- wherein, in Chemical Formula 1,
- R1 and R2 are the same as or different from each other, and each independently a substituted or unsubstituted C1 to C60 alkyl group;
- or a substituted or unsubstituted C6 to C60 aryl group;
- or groups adjacent to each other bond to each other to form a substituted or unsubstituted C6 to C60 aromatic hydrocarbon ring or a substituted or unsubstituted C2 to C60 heteroring;
- L1 is a direct bond;
- a substituted or unsubstituted C6 to C60 arylene group;
- or a substituted or unsubstituted C2 to C60 heteroarylene group;
- X1 to X3 are the same as or different from each other, and each independently N;
- or CRa, and at least one thereof is N;
- Ra, Ar2 and Ar4 are the same as or different from each other, and each independently selected from the group consisting of hydrogen;
- a substituted or unsubstituted C1 to C60 alkyl group;
- a substituted or unsubstituted C6 to C60 aryl group;
- a substituted or unsubstituted C2 to C60 heteroaryl group;
- —SiRR′R″;
- —P(═O)RR′;
- and an amine group unsubstituted or substituted with 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, or two or more groups adjacent to each other bond to each other to form a substituted or unsubstituted C6 to C60 aromatic hydrocarbon ring or a substituted or unsubstituted C2 to C60 heteroring;
- R3 to R11 are the same as or different from each other, and each independently selected from the group consisting of hydrogen;
- deuterium;
- a halogen group;
- and —CN;
- R, R′ and R″ are the same as or different from each other, and each independently hydrogen;
- a substituted or unsubstituted C1 to C40 alkyl group;
- or a substituted or unsubstituted C6 to C40 aryl group;
- and
- m is an integer of 1 to 6, and when m is 2 or greater, substituents in the parentheses are the same as or different from each other.
