| Abstract: | Twenty-two of the 2-(substituted styryl)-5-substituted benzoxazole compounds were synthesized by condensation of the corresponding 2-methyl benzoxazole or 5-t-Bu-2-methylbenzoxazole with benzaldehyde, substituted benzaldehyde in the medium of KOH/DMF respectively. Their m. p. , vmax of UV spectra 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. |
