【Abstract】 2, 6-Distyryl benzo-[l, 2d; 4, 5d’]-bisoxazole and 2, 6-distyryl benzo-[l,2d;5, 4d’]-bisoxazole as well as six derivatives of each of them were synthesized by condensation of the corresponding 2,6-dimethyl benzo-[l,2d; 4,5d’]-bisoxazole or 2, 6-dimethyl benzo-[l,2d; 5, 4d’]-bisoxazole respectively with benzaldehyde or substituted benzaldehydes in the presence of alkali. The m.p., λmax of UV spectra and fluorescence emission spectra, as well as laser properties of the products are listed in tables.更多还原
