The present specification provides a heterocyclic compound and an organic light emitting device using the same.
First claim
Opening claim text (preview).
The invention claimed is: 1. A heterocyclic compound represented by the following Chemical Formula 1: wherein, in Chemical Formula 1, R is a substituted or unsubstituted aryl group, R1 is a substituted or unsubstituted alkyl group; or a substituted or unsubstituted aryl group, R2 to R8 are the same as or different from each other, and each dependently hydrogen; deuterium; a substituted or unsubstituted aryl group; or a substituted or unsubstituted heteroring group including one or more of N, O and S atoms, wherein when R1 is a substituted or unsubstituted aryl group, at least one of R2 to R8 is a substituted or unsubstituted aryl 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 at least one of R2 to R8 is any one of the following structures: 3. The heterocyclic compound of claim 1 , wherein the heterocyclic compound represented by Chemical Formula 1 is represented by any one of the following structures:
