摘要
PURPOSE: A dibenzotetracene-based derivative is provided to have excellent luminous efficiency, color purity, and lifetime, and to have excellent structure with moderate color coordination. CONSTITUTION: A dibenzotetracene-based derivative is represented by chemical formula F. In an organic electroluminescent device, one or more organic thin film layers including a light emitting layer are inserted between a negative electrode and a positive electrode. At least one layer of the organic thin film layers includes one or a combination of two or more kinds of the dibenzotetracene-based derivative. The dibenzotetracene-based derivative contains a fluorescence green host compound or a light-emitting green dopant compound in the light emitting layer of the organic thin film layers.
