Synthesis of optically active methacrylic oligomeric models and polymers bearing the side-chain azo-aromatic moiety and dependence of their chiroptical properties on the polymerization degree

Three oligomeric models (dimer, trimer and tetramer) of optically active methacrylic polymers containing in the side-chain the pyrrolidinyl group of one single configuration linked through the nitrogen atom to the azobenzene chromophore and the related homopolymers in a wide range of average polymerization degree (13
