Abstract

The present specification describes a novel polycyclic compound and an organic electroluminescent device using the same.

First claim

What is claimed is:

1. A compound represented by the following Formula 1:

Formula 1 is represented by any one of the following Formulae 1-1 to 1-4,

in Formulae 1-1 to 1-4,
X is O, S, or NAr,
n is an integer of 0 to 6,
when n is 2 or more, a plurality of R5's is the same as or different from each other,
R1 to R5 are the same as or different from each other, and are each independently hydrogen, or combine with an adjacent group to form a substituted or unsubstituted ring,
R6 to R10 are the same as or different from each other, and are each independently hydrogen; deuterium; a halogen group; a nitrile group; a nitro group; a hydroxy group; a carbonyl group; an ester group; an imide group; an amino group; a substituted or unsubstituted silyl group; a substituted or unsubstituted boron 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 aralkyl group; a substituted or unsubstituted aralkenyl group; a substituted or unsubstituted alkylaryl group; a substituted or unsubstituted amine group; a substituted or unsubstituted arylphosphine group; a substituted or unsubstituted phosphine oxide group; a substituted or unsubstituted aryl group; or a substituted or unsubstituted heterocyclic group, or combine with two or more adjacent groups in R6 to R10 to form a substituted or unsubstituted ring, and
Ar is hydrogen; a substituted or unsubstituted heteroaryl alkyl group; a substituted or unsubstituted aryl group; or a substituted or unsubstituted heterocyclic group.

2. The compound of claim 1 , wherein X is NAr.

3. The compound of claim 1 , wherein Ar is an aryl group which is unsubstituted or substituted with one or two or more substituents selected from the group consisting of deuterium, a nitrile group, a substituted or unsubstituted alkyl group, a substituted or unsubstituted amine group, a substituted or unsubstituted aryl group, and a substituted or unsubstituted heterocyclic group; or a heterocyclic group which is unsubstituted or substituted with one or two or more substituents selected from the group consisting of deuterium, a nitrile group, a substituted or unsubstituted alkyl group, a substituted or unsubstituted amine group, a substituted or unsubstituted aryl group, and a substituted or unsubstituted heterocyclic group.

4. The compound of claim 1 , wherein Ar is a phenyl group; a naphthyl group; a biphenyl group; a terphenyl group; a quarterphenylene group; a fluorene group; a fluoranthene group; an anthracene group; a chrysene group; a phenanthrenyl group; a pyrene group; an amine group; a pyridine group; a pyrimidine group; a triazine group; a quinoline group; a quinazoline group; a carbazole group; a dibenzothiophene group; a dibenzofuran group; a furan group; a thiophene group; or a phenanthroline group, and Ar is substituted with one or two or more substituents selected from the group consisting of deuterium; a nitrile group; an alkyl group having 1 to 10 carbon atoms; a phenyl group; a naphthyl group; a biphenyl group; a terphenyl group; a quarterphenylene group; a fluorene group; a fluoranthene group; an anthracene group; a chrysene group; a phenanthrenyl group; a pyrene group; an amine group; a pyridine group; a pyrimidine group; a triazine group; a quinoline group; a quinazoline group; a carbazole group; a dibenzothiophene group; a dibenzofuran group; a furan group; a thiophene group; and a phenanthroline group, or is unsubstituted or substituted with a substituent to which two or more substituents are linked.

5. The compound of claim 1 , wherein the compound represented by Formula 1-1 is represented by any one of the following Formulae 1-1-1 to 1-1-195:
