Conclusions

  1. 1.

    The rate constants of dark cyclization of spiropyrans of the naphtho[1,8-b,c]furan series increase with an increase in the polarity of the solvent; this is due to the role of the state with charge transfer during a change in the hybridization of the carbon spiro atom.

     
  2. 2.

    The photochromism reaction takes place through a triplet state in sensitized photolysis.
