The results showed that the maximum UV absorption wavelengths of those 1,3,4-oxadiazole derivatives in dichloromethane were in the range of 268~327 nm, and their maximum photoluminescent wavelengths in dichloromethane and solid film were located at 332~390 nm and 359~439 nm, respectively. The 1,3,4-oxadiao1e derivatives exhibit a first endothermal peak at 120~328℃ in the DSC heating process, and the symmetrical 1,3,4-oxadiazole derivatives display a higher melting temperature. The CV curves of those 1,3,4-oxadiazole derivatives indicate that the reductive potentials of the 1,3,4-oxadiazole derivatives are located at -1.03~0.98 V, and their LUMO(the lowest unoccoupied molecual orbit) energy levels are -3.71~-3.76eV.
