Abstract

The present disclosure relates to a novel organic compound and an organic electroluminescent device comprising the same, and more particularly, to an organic compound having excellent lifespan, efficiency, electrochemical stability, and thermal stability, and an organic electroluminescent device comprising the same.

Claims (5)

1. A compound selected from the group consisting of:

2. An organic electroluminescent device including: a first electrode; a second electrode provided to face the first electrode; and one or more organic material layers provided between the first electrode and the second electrode, wherein at least one of the one or more organic material layers comprises the compound according to claim 1 .

3. The organic electroluminescent device of claim 2 , wherein the organic material layer is selected from the group consisting of a hole injection layer, a hole transport layer, an electron blocking layer, a light emitting layer, a hole blocking layer, an electron transport layer, and an electron injection layer.

4. The organic electroluminescent device of claim 2 , wherein the organic material layer is the light emitting layer.

5. The organic electroluminescent device of claim 2 , wherein the compound according to claim 1 is used as a dopant material for the light emitting layer.
