Abstract

The present specification relates to a carbazole derivative of Chemical Formula 1, a coating composition including the carbazole derivative, an organic light emitting device using the same and a method for manufacturing the same.

Claims (19)

1. A carbazole derivative having any one of the following structural formulae:

2. A coating composition comprising the carbazole derivative of claim 1 .

3. The coating composition of claim 2 , further comprising a p-doping material.

4. The coating composition of claim 2 , further comprising:

a monomer comprising a thermocurable group or a photocurable group; or

a monomer comprising a terminal group capable of forming a polymer by heat.

5. An organic light emitting device comprising:

a cathode;

an anode; and

one or more organic material layers provided between the cathode and the anode,

wherein one or more layers of the organic material layers comprise a cured material of the coating composition of claim 2 .

6. The organic light emitting device of claim 5 , wherein the organic material layer comprising a cured material of the coating composition is a hole transfer layer, a hole injection layer, a layer carrying out hole transfer and hole injection at the same time, or a light emitting layer.

7. A method for manufacturing an organic light emitting device comprising:

preparing a substrate;

forming a cathode or an anode on the substrate;

forming one or more organic material layers on the cathode or the anode; and

forming an anode or a cathode on the organic material layers,

wherein the forming of organic material layers comprises forming one or more organic material layers using the coating composition of claim 2 .

8. The method for manufacturing an organic light emitting device of claim 7 , wherein the forming of organic material layers using the coating composition comprises coating the coating composition on the cathode or the anode; and heat treating or light treating the coated coating composition.
