A series of novel unsymmetrical stilbene-based 1,3,4-oxadiazole derivatives were efficiently synthesized by a four-pots reaction sequence. All of the title compounds were characterized by MS, 1H-NMR and elemental analysis. UV–Vis absorption and fluorescence emission spectra of the compounds were investigated in dilute chloroform solution; the compounds exhibit strong blue-green fluorescence ranged from 397 to 499 nm and show potential for application in organic optical materials.
