Synthesis and Performance Study of 5, 5 '- Diaryl - 2, 2' Bi (1,3,4-oxadiazoles )

1,3,4-oxadiazole (OXD) and its derivatives have excellent thermal stability and oxidation resistance and strong blue fluorescence emission [.Six novel compounds have been designed and synthesized And their structures were confirmed by 1 HNMR,FT-IR,MS, UV-vis absorption results showed that the maximum absorption wavelength appeared at 430nm,and fluorescence spectroscopy results showed that emit strong purple fluorescence in DMF solution.
