Organic Photochromics

The results of targeted fundamental studies of the photochromism of organic compounds, systems and materials on their basis, performed at the Photochemistry Center of the Russian Academy of Sciences, have been analyzed. The scientific basis for the creation of photochromic materials for light-modulating devices and photosensitive recording media for three-dimensional (3D) optical memory with acceptable functional properties has been developed. Practically significant advances have been achieved in the development of photochromic nanoparticles, photochromic optical sensors, and light-adaptive coatings with negative photochromism. The prospects of using photochromic compounds in biomedical technologies are noted.
