Studies on 2, 5-Diaryloxadiazoles (Ⅲ)—The Synthesis, Spectra and optical Properties of trans-2-{4-[2-(4-R-phenyl) ethenyl]phenyl}-5-(4-biphenyl)oxadiazole
【Abstract】 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.
