Novel organic electroluminescent compounds and organic electroluminescent device using the same

摘要

PURPOSE: An organic electroluminescent compound is provided to excellent luminous efficiency and life time properties, thereby using for manufacturing an organic electroluminescent device of which driving life time is very superior. CONSTITUTION: An organic electroluminescent compound is in chemical formula 1. An organic electroluminescent device comprises the organic electroluminescent compound, the organic electroluminescent compound is using as material for hole injection or hole transport. The organic electroluminescent compound comprises a first electrode, a second electrode, and one or more organic material layer between the first electrode and the second electrode. The organic layer comprises the organic electroluminescent compound in chemical formula 1. The organic layer comprises a light emitting layer and a charge generating layer at the same time.
