Synthetic Study of Organic Electroluminescent Materials

Starting from benzoylhydrazine and isophthaloyl chloride,synthetic method and technology of (1,3-bis (5-phenyl)-1,3,4-oxadiazol-2-yl)benzene are studied in details. The yield of product is 56.1% and the purity is 99.9% by the analysis of HPLC. The affection laws of factors such as solvent and method for purification are discussed. The structure and properties of the material are also tested and its PL peaks are between 400~472 nm with its melting point in the range of 247~248℃.
