<p>PURPOSE: A compound is provided to have e function as a light emitting host together with moderate dopant, to function as a hole injection and transfer or an electron injection and transfer material, and to provide an organic light-emitting diode with excellent lifetime, efficiency, driving voltage, electrochemical stability, and thermal stability. CONSTITUTION: A compound is represented by chemical formula 1; and a combination of chemical formula 2 or 3. The compound has triplet excitation energy of 2.0 eV or more. An organic optoelectronic diode includes a positive electrode, a negative electrode, and one or more organic thin film layer. At least one layer of the organic thin film layer includes the compound for the organic optoelectronic diode. The organic thin layer is selected from a light emitting layer, a hole transfer layer, an electron transfer layer, an electron injection layer, a hole-blocking layer, and a combination thereof.</p> |
