NEW OXADIAZOLE FOR SYNTHESIZING LUMINESCENT POLYMER AND SYNTHETIC METHOD OF NEW LUMINESCENT POLYMER AND ELECTRIC LUMINESCENT ELEMENT USING THEM

摘要

PURPOSE: New oxadiazole for polymerizing a luminescent polymer and synthetic methods of new luminescent polymers and electoluminescent elements using them are provided which promote the luminescent efficiency of electoluminescent elements. CONSTITUTION: New oxadiazole for polymerizing a luminescent polymer and synthetic methods of new luminescent polymers and a method for making luminescent elements are described which comprise: (a)obtaining oxadiazole which enable to excel in an electron injection and transfer capability in a luminescent polymer; (b)synthesizing luminescent polymers of formula (P-1) and (P-2) having a solubility in an organic solvent and an excellent electron and hole transfer capability by reacting them with a compound having a hole transfer capability; (c)forming semitransparent electrodes, polymer luminescent layers comprising the formula (P-1) and (P-2) and metal electrodes in regular series.
