Abstract

A novel compound represented by Chemical Formula 6 below and an organic electroluminescent device including the same are disclosed. The inclusion of the compound in an organic material layer of an organic electroluminescent device, preferably as a light emitting layer, can improve luminous efficiency, driving voltage, lifetime and the like of the organic electroluminescent device:

Claims (7)

1. A compound selected from the group consisting of the following compounds:

2. An organic electroluminescent device comprising:

an anode;

a cathode; and

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

wherein at least one of the one or more organic material layers includes a compound of claim 1 .

3. The organic electroluminescent device of claim 2 , wherein the organic material layer includes one or more layers selected from the group consisting of a hole injection layer, a hole transport layer, a hole transport auxiliary layer, an electron transport layer, an electron transport auxiliary layer and a light emitting layer.
