Abstract

A material for an organic electroluminescent device and an organic electroluminescent device including the same, the material including a monoamine compound represented by the following Formula 1:

Claims (12)

1. A material for an organic electroluminescent device, the material comprising a monoamine compound represented by the following Formula 1:

wherein, in Formula 1,

R 1 and R 2 are each independently a hydrogen atom, a halogen atom, an alkyl group having 1 to 15 carbon atoms, a substituted or unsubstituted aryl group having 6 to 30 ring carbon atoms, or a substituted or unsubstituted heteroaryl group having 1 to 30 ring carbon atoms, and

Ar 1 includes a substituted or unsubstituted naphthalenylphenyl group.

2. The material for an organic electroluminescent device as claimed in claim 1 , wherein all dibenzofuranyl groups that are directly bonded with a nitrogen atom of the monoamine are bound to the nitrogen atom at a 3 position of the dibenzofuranyl group.

3. The material for an organic electroluminescent device as claimed in claim 1 , wherein the compound represented by Formula 1 includes the following compound:

4. An organic electroluminescent device comprising a material for an organic electroluminescent device, wherein the material for an organic electroluminescent device includes a monoamine compound represented by the following Formula 1:

wherein, in Formula 1,

R 1 and R 2 are each independently a hydrogen atom, a halogen atom, an alkyl group having 1 to 15 carbon atoms, a substituted or unsubstituted aryl group having 6 to 30 ring carbon atoms, or a substituted or unsubstituted heteroaryl group having 1 to 30 ring carbon atoms, and

Ar 1 includes a substituted or unsubstituted naphthalenylphenyl group.

5. The organic electroluminescent device as claimed in claim 4 , wherein the material for an organic electroluminescent device is included in a hole transport layer.

6. The organic electroluminescent device as claimed in claim 4 , wherein the compound represented by Formula 1 includes the following compound:
