The thermochromic and photochemical properties of bis-spiropyranes

Conclusions

  1. 1.

    The spectral properties of the indoline bis-spiropyrans are substantially different from the properties of the components of their monoderivatives.

  2. 2.

    In bis-spiropyrans with two open pyrane rings the absorption band is split into long wavelength and short wavelength components.

  3. 3.

    The ratio of the intensities of the short wavelength and long wavelength components is determined by the angle between the chromophores and corresponds to the theoretically calculated ratio.
