Abstract

The present specification relates to a hetero-cyclic compound and an organic light emitting device comprising the same.

First claim

The invention claimed is:

1. A hetero-cyclic compound represented by the following Chemical Formula 1:

wherein, in Chemical Formula 1,
R1 is deuterium; a nitrile group; a nitro group; a hydroxyl group; a carbonyl group; an ester group; an imide group; an amide group; a substituted or unsubstituted alkyl group; a substituted or unsubstituted cycloalkyl group; a substituted or unsubstituted alkoxy group; a substituted or unsubstituted aryloxy group; a substituted or unsubstituted alkylthioxy group; a substituted or unsubstituted arylthioxy group; a substituted or unsubstituted alkenyl group; a substituted or unsubstituted silyl group; a substituted or unsubstituted boron group; a substituted or unsubstituted amine group; a substituted or unsubstituted arylphosphine group; a substituted or unsubstituted aryl group; or a substituted or unsubstituted heteroaryl group;
L1 is a direct bond; a substituted or unsubstituted arylene group; or a substituted or unsubstituted heteroarylene group;
Ar1 is a structure represented by the following Chemical Formula 3;
m is an integer of 1 to 4;
n is an integer of 0 to 3;
1≤n+m≤4;
and when m and n are each 2 or greater, each of L1-Ar1, and R1 is the same as or different from each other, respectively,

wherein, in Chemical Formula 3,
X1 is N or CR11, X2 is N or CR12 and X3 is N or CR13; at least one of X1 to X3 is N; and
any one of G2 to G4 and R11 to R13 is a site bonding to L1 of Chemical Formula 1, and the rest are the same as or different from each other and each independently hydrogen; deuterium; a nitrile group; a nitro group; a hydroxyl group; a carbonyl group; an ester group; an imide group; an amide group; a substituted or unsubstituted alkyl group; a substituted or unsubstituted cycloalkyl group; a substituted or unsubstituted alkoxy group; a substituted or unsubstituted aryloxy group; a substituted or unsubstituted alkylthioxy group; a substituted or unsubstituted arylthioxy group; a substituted or unsubstituted alkylsulfoxy group; a substituted or unsubstituted arylsulfoxy group; a substituted or unsubstituted alkenyl group; a substituted or unsubstituted silyl group; a substituted or unsubstituted boron group; a substituted or unsubstituted amine group; a substituted or unsubstituted arylphosphine group; a substituted or unsubstituted aryl group; or a substituted or unsubstituted heteroaryl group,
with the proviso that when R1, L1 and/or Ar1 contain a carbazolyl group, the carbazolyl group is not substituted with a nitrile group.

2. The hetero-cyclic compound of claim 1 , wherein Chemical Formula 1 is represented by any one of the following Chemical Formulae 1-1 to 1-4:

wherein, in Chemical Formulae 1-1 to 1-4,
definitions of L1, Ar1, R1 and n are the same as in Chemical Formula 1.

3. The hetero-cyclic compound of claim 1 , wherein Chemical Formula 1 is selected as any one of the following compounds:
