Abstract:
PURPOSE: An organic electroluminescent compound is provided to have excellent red-light luminous efficiency and life time properties. CONSTITUTION: An organic electroluminescent compound is in chemical formula 1. In chemical formula 1, L is single bond, substituted or non-substituted (C1-30) alkylene, substituted or non-substituted (C6-30) arylene, substituted or non-substituted heteroarylene, substituted or non-substituted 5-7 membered heterocycloalkylene of substituted or non-substituted (C3-30) cycloalkylene, or substituted or non-substituted (C6-C30) arylene - (C1-C30) alkylene. An organic electroluminescent device comprises a first electrode, a second electrode, and one or more layers of organic material inserted between the first electrode and the second electrode. The organic material layer comprises one or more of the organic electroluminescent compounds, and one or more of photo-dopant.
Abstract:
PURPOSE: A novel compound for electronic materials is provided to ensure excellent luminous efficiency and good lifetime property of materials when being included in an organic light-emitting device, thereby producing an OLED device with excellent driving durability of a device. CONSTITUTION: A novel compound for electronic materials is represented by chemical formula 1. The organic light-emitting device comprises a first electrode, a second electrode, and at least one organic layer(3~7). The organic layer is interposed between the first electrode and the second electrode. The organic layer includes at least one compound for electronic materials.
