摘　　要：Eight of trans-2-{4-[2-(4-R-Phenyl) ethenyl] phenyl} -5- (4-biphenyl ) oxadiazoles (R=H, i-Pr, t-Bu, Ph, OMe, F, Cl, Br) were synthesized. Their UV, MS, FL spectra,fluorescence quantum yields and laser conversion efficiencies as well as fluorescence lifetime,laser turning range are given and discussed.Eight of trans-2-{4-[2-(4-R-Phenyl) ethenyl] phenyl} -5- (4-biphenyl ) oxadiazoles (R=H, i-Pr, t-Bu, Ph, OMe, F, Cl, Br) were synthesized.
