Conclusion

  1. 1.

    The spiropyrans investigated have a weakly pronounced bipolar structure of the colored form and are characterized by anomalously high activation parameters of the thermal reaction in toluene solutions.

  2. 2.

    The change in the shape of the spectrum in the process of photo-activation and the anomalous parameters of the decoloration reaction are due to the formation of associates of the colored form in toluene solutions.
