Side chain liquid crystal polyacrylates and polysiloxanes containing photochromic spiropyran moieties of different structures were synthesized. They exhibited photochromic properties substantially different from the properties of amorphous photochromic polymer. Kinetics of the reversible photochromic conversions as well as spectral properties of the polymers depended on temperature and phase conditions. Incorporation of spiropyran groups in a macromolecule in turn results in change of structure and physical properties of the mesophase. This was associated with the conformational changes accompanying the spiropyran → merocyanine conversion and with aggregation of the merocyanine form of the photochrome. Possible applications of the polymers for the imaging technologies will be discussed.
