摘要：

The spectral and kinetic properties of 5-(4,5-diphenyl-1,3-oxazol-2-yl)spiro[indoline-naphthopyran] derivatives were studied by experimental and theoretical methods. The additional long-wavelength maximum in the absorption spectra of compounds studied is due to the introduction of a diphenyloxazole fragment and corresponds to a pi-pi* electronic transition with a partial charge transfer character. Substituents have little effect on the kinetic parameters of the spironaphthopyrans studied.
