Abstract

Abstract: Twenty-two of the 2-(substituted styryl)-5-substituted benzoxazole compounds were synthesized by condensation of the corresponding₂-methyl benzoxazole or 5-t-Bu-2-methylbenzoxazole with benzaldehyde, substituted benzaldehyde in the medium of KOH/DMFrespectively. Their m. p., v_max of UVspectra and fluorescence emission spectra, fluorescence quantum yields, as well as Stokes shifts of the compounds were examined. The solvent effect of compounds 1 and 15 was also discussed.

Key words: Substituted benzoxazole compounds, UV, FL, Solvation effect
