NOVEL ORGANIC ELECTROLUMINESCENT COMPOUNDS AND ORGANIC ELECTROLUMINESCENT DEVICE USING THE SAME

摘要

PURPOSE: An organic electroluminescent compound and organic electroluminescent device using the same are provided to secure high luminous efficiency, color purity, and lifetime. CONSTITUTION: An organic electroluminescent compound is represented by formula 1. An organic electroluminescent device comprises the organic electroluminescent compound. The organic electroluminescent compound is used as a host material of a light-emitting layer. The organic electroluminescent device comprises a first electrode, second electrode, and at least one organic layer(3~7). The organic layer is interposed between the first electrode and second electrode. The organic layer comprises one or more organic electroluminescent compounds. The organic layer comprises the light-emitting layer(5).
