ABSTRACT:
The invention relates to photochromic monomers based on benzothiophenes and a method for preparing them, and to photochromic polymers-polyazomethines that are reversibly photocontrollable due to the introduction of photochromic fragments from the class of dihetarylethenes into their structure. The invention provides photochromic photocontrollable polymers for the creation of new information technologies.
