Аннотация:One of the most urgent problems in the informational nanotechnology is the development of photochromic recording media for three-dimensional optical memory with a high information capacity. Usually these light-sensitive materials are developed using thermally irreversible photochromic compounds, particularly 1,2-diarylethenes, in polymer binders [1]. Unfortunately, the information capacity (resolution) of these recording media is limited by diffusion and low content (up to 5 mass %) of photochromic compounds in a polymer matrix.
This report represents synthesis and spectral-kinetic study of photochromic three-dimensional silicone polymers (coatings) based on 1,2-dihetarylethenes with N-hydroxyethyl and N-allyl groups, polysiloxanes and polysilazanes. The polymers obtained contain photochromic moieties linked to the polymer chain by covalent bonds that allow achieving of photochromic units with a high concentration (up to 40%).
