The Synthesis and Spectral Properties of Stilbenylbisbenzoxazoles

A series of fluorescent compounds of 5,5'-disubstituted-2,2'-stilbenyl-4,4'-diyl-bisbenzoxazole were synthesized through cyclization and condensation reactions using p-cyano benzyl chloride and substituted o-aminophenols as starting materials. The UV absorption spectra and the fluorescence emission spectra were obtained by UV and fluorescence spectrophotometers. The fluorescence quantum yields were determined using quinine sulfate in 0.5mol/l H2SO4 as fluorescence standard. The relationships between molecular structure and ultraviolet, fluorescence properties were investigated.
