Using conducting materials as emission layer (EML), Organic light-emitting diode (OLEDs) has been applied on monitors. Its contribution has drawn more and more attention from academic and industrial circles. Currently the components of electroluminescent are composed in the way of multi-layers, that means to paint a coating of electron transport layer (ETL) and hole transport layer (HTL) separately between electrode and emission layer, so as to control the injection balance of electron and hole and manufacture best luminous element. This study focuses on synthesizing 1,3,4-oxadiazole ring that has electron transport capacity to be the main frame, and finding out the effect of its 2,5 positions to the derivatizing reaction of non-aromatic substituent and various reagents to its productive rate. This report uses 4-nitrobenzoyl chloride and various benzohydrazide of substitutional group to carry out condensation reaction and obtained dicarboxylic hydrazide compound, then through various cyclization reagents to carry out cyclization reaction to form 2,5-aromatic base oxadiazole derivate. There after, following up the study of various nitro- hydrogenation reduction reaction and synthesized 1,3,4-oxadiazole derivate that contains aminopheny. Finally, using amino group, ketones, diphenyl ketone, methyl iodide, and benzoyl chloride to carry out various condensation and substitution reactions, so as to prepare various derivatives of 2,5-aromatic base, -1,3,4- oxadiazole (2,5-diaryl-1,3,4- oxadiazole) ring organic luminous materials.
