Synthesis and Application Properties of New Hole Transport Material

bis(4-nitrobenzoyl)hydrazine was obtained through the reaction of p-nitrobenzoyl chloride and hydrazine hydrate. The compound was cyclized under the action present of phosphorus oxychloride, and deoxidized with Fe powder to prepare 2,5-bis(4-aminophenyl)-1,3,4-oxadiazole. Then 2,5-bis4-N,N-bis(4-methylphenyl)amino]phenyl]-1,3,4-oxadizole was synthesized in toluene using cuprous chloride as catalyst and o-phenanthroline as cocatalyst. The structure and composition of products were characterized by melting point, UV spectrum, IR spectrum, ~1H-NMR, MS and EA. Oxidation potential and electrophotoconductive properties of the objective compound were determined, and showed that it has a good carrier transmission performance.
