Benzothiazospironaphthooxazine compounds with photochromic property have been synthesized by the reaction of benzothiazole derivatives with 1-nitroso-2-naphthol under microwave irradiation, in which triethylamine and anhydrous ethanol were used as the catalyst and the solvent, respectively. The structures of title compounds were characterized by elemental analyses, IR MS and H-1 NMR spectra. The solvent and fluorescence effects of these compounds were studied by UV and fluorescence spectrometries, respectively. The results demonstrated that these compounds show good fluorescence and their ring opening forms have a good linear correlation with solvent polarity.
