Abstract

The present application provides a hetero-cyclic compound capable of significantly enhancing lifespan, efficiency, electrochemical stability and thermal stability of an organic light emitting device, and an organic light emitting device containing the hetero-cyclic compound in an organic compound layer.

First claim

The invention claimed is:

1. A hetero-cyclic compound represented by the following Chemical Formula] 2 or 3:

wherein, in Chemical Formula 2 and 3,
at least one of R1 to R5 is represented by -(L2)p-(Z2)q and the rest are hydrogen; or deuterium,
at least one of R12 to R16 is represented by -(L3)r-(Z3)s, and the rest are hydrogen; or deuterium,
L2 and L3 are the same as or different from each other, and each independently a direct bond; or a substituted or unsubstituted C 6 to C 60 arylene group,
Z2 and Z3 are the same as or different from each other, and each independently selected from the group consisting of a substituted or unsubstituted pyridine group; a substituted or unsubstituted pyrimidine group; a substituted or unsubstituted triazine group; a substituted or unsubstituted phenanthroline group; a substituted or unsubstituted quinoline group; a substituted or unsubstituted carbazole group; a substituted or unsubstituted dibenzofuran group; a substituted or unsubstituted dibenzothiophene group; a substituted or unsubstituted anthracene group; a substituted or unsubstituted phenanthrene group; a substituted or unsubstituted biphenyl group; a substituted or unsubstituted naphthyl group; and —P(═O)RR′,
p and r are an integer of 0 to 4;
q and s are an integer of 1 to 4;
R6 to R11 are hydrogen or deuterium; and
R, and R′ are the same as or different from each other, and each independently hydrogen; deuterium; —CN; a substituted or unsubstituted C 1 to C 60 alkyl group; a substituted or unsubstituted C 3 to C 60 cycloalkyl group; a substituted or unsubstituted C 6 to C 60 aryl group; or a substituted or unsubstituted C 2 to C 60 heteroaryl group.

2. The hetero-cyclic compound of claim 1 , wherein Chemical Formula 2 or 3 is represented by any one of the following compounds:
