Abstract

Disclosed are a heterocyclic compound represented by the following Chemical Formula having proper energy level, and excellent electrochemical stability and thermal stability, and an organic light emitting device using the same:

First claim

The invention claimed is:

1. A heterocyclic compound represented by the following Chemical Formula 3:

wherein, in Chemical Formula 3,
X is O or S;
R1 is a substituted or unsubstituted alkyl group or a substituted or unsubstituted aryl group,
R2 to R5 are the same as or different from each other, and each independently hydrogen; deuterium; a substituted or unsubstituted alkenyl group; a substituted or unsubstituted phosphine oxide group; a substituted or unsubstituted aryl group; or a substituted or unsubstituted heteroring group including one or more of N, O and S atoms,
R6 to R8 are each independently hydrogen, and
at least one of R2 to R5 is a substituted or unsubstituted alkenyl group; a substituted or unsubstituted aryl group; a substituted or unsubstituted phosphine oxide group; or a substituted or unsubstituted heteroring group including one or more of N, O and S atoms.

2. The heterocyclic compound of claim 1 , wherein R2 to R5 are the same as or different from each other, and each dependently hydrogen; an alkenyl group; an aryl group; a phosphine oxide group; or a heteroring group including one or more of N, O and S atoms,
wherein the alkenyl group; the aryl group; the phosphine oxide group; and the heteroring group including one or more of N, O and S atoms are unsubstituted or substituted with one, two or more substituents selected from the group consisting of deuterium, a nitrile group, a substituted or unsubstituted alkyl group, a substituted or unsubstituted alkenyl group, a substituted or unsubstituted aryl group, a substituted or unsubstituted silane group, a substituted or unsubstituted phosphine oxide group, and a substituted or unsubstituted heteroring group including one or more of N, O and S atoms, or two or more substituents bond to each other to form an aliphatic ring, an aromatic ring, an aliphatic heteroring or an aromatic heteroring, or form a spiro bond.

3. The heterocyclic compound of claim 1 , wherein at least one of R2 to R5 is any one of the following structures:

4. A heterocyclic compound represented by the following Chemical Formula 3:

wherein the heterocyclic compound represented by Chemical Formula 3 is represented by any one of the following structures:
