Özet:

 

Six novel 2,5-bis[4-(2-arylvinyl)phenyl]-1,3,4-oxadiazoles  were synthesized by introducing 1,3,4-oxadiazole moiety into the  stilbene skeleton.  The synthesis route included the cyclization of  p-toluic acid and hydrazine hydrate catalyzed by polyphosphoric acid  (PPA), bromination of 1,3-dibromo-5,5-dimethylhydantoin (DBDMH),  esterification, and the Wittig-Horner reaction.  All the title  compounds were characterized by 1H-NMR, MS, and elemental analysis.  UV-Vis absorption and fluorescence emission spectra in THF solution  were investigated; the compounds may have potential for use in organic optical materials.
