ORGANIC ELECTROLUMINESCENCE DEVICE USING THE TRIPHENYLENE DERIVATIVE

摘要

PURPOSE: A triphenylene based compound and an organic electroluminescent device using the same are provided to enhance chromatic purity and luminous efficiency of the organic electroluminescent device in the application of a light-emitting layer. CONSTITUTION: A triphenylene based compound is represented by chemical formula 1. The organic electroluminescent device comprises a positive electrode, cathode, one or more organic layers interposed between the anode and cathode. One or more of the organic layers include the compound. The organic layer is selected from a group comprised of the light-emitting layer, a hole injection layer(HIL) and a hole-transport layer. The organic layer including the compound represented by chemical formula 1 is phosphorescence host or fluorescence hoste material of the light-emitting layer.
