Alk=CH3-C10H21, methods of obtaining them, photochromic polymers based on them, method of obtaining photochromic monomers and their application. The proposed materials exhibit thermal irreversibility of photochromic transformations and properties, making it possible to use photochromic polymers in two-photon random access optical memory.
EFFECT: obtaining materials with thermal irreversibility of photochromic transformations and properties, making it possible to use photochromic polymers in two-photon random access optical memory.
