Conclusions

  1. 1.

    A scheme of the photochemical transformations in photolysis of spiropyrans (SSP) of the dihydroisobenzofuran series was proposed: The elementary rate constants of formation of long-lived isomers of the merocyanine form were determined.

  2. 2.

    Photodecolorization of the merocyanine form of SPP is also observed together with dark decolorization.

  3. 3.

    The lower boundaries of the extinction coefficients of the photoinduced merocyanine forms and the upper limits of the quantum yields of photocoloration were estimated.
