  The reaction of 6-methoxynaphtho[1,8-bc]pyran-3-one with dimethylformamide dimethyl acetal gave the corresponding 2-dimetbylaminomethylidene derivative which reacted with amines to form new 2-aminomethylidene-6-methoxynaphtho[1,8-bc]pyran-3-ones via replacement of the dimethylamino group. 2-Dimethylaminomethylidene-6-methoxynaphtho[1,8-bc]pyran-3-one also reacted with 2,3-dimethylchromenium perchlorate and 1,2,3,3-tetramethyl-3H-indolium perchlorate to give the corresponding merocyanine dyes. The latter were examined for chemosensor and photochromic properties.

  New spiro compounds of the indole, phthalazine, isobenzofuran, and benzopyran series, containing a fused benzopyranone fragment in the chromene moiety, were synthesized. Indole derivatives were found to exhibit photochromic properties under stationary conditions at 293 K. The thermal stability of merocyanine isomers sharply decreases upon introduction of electron-withdrawing nitro group into the indole fragment and fusion of a benzene ring to the chromene fragment.

  Novel photochromic spirobipyrans containing benzothiazole group in the 2H-chromene moiety have been synthesized. The spirobipyrans combine with Co2+, Ni2+, Zn2+, and Cu2+ ions to give intensely colored complexes of merocyanine form with long-wavelength absorption bands at lambda > 600 nm.
