COMPOUND WITH HIGH EFFICIENCY AND ORGANIC LIGHT EMITTING DEVICE INCLUDING THE SAME

摘要

PURPOSE: A compound for High efficiency organic electroluminescent device is provided to improve electron injection properties through the embodying of characteristic according to independent energy-level and to improve efficiency by controlling charge balance in an electroluminescent layer. CONSTITUTION: A compound for High efficiency organic electroluminescent device is in the chemical formula 1: A-C-B. In the chemical formula 1, A unit and B unit are different each other, The HOMO energy level and the LUMO energy level of the A unit and B unit are crossed each other differently each other. The A unit, B unit and C unit comprise a conjugated structure, and the conjugated structure is expanded by connecting each other. An organic electroluminescent device comprises a first electrode, a second electrode and an electroluminescent layer. The electroluminescent layer comprises a host and a dopant. The host comprises the compound.
