Whereas chiral monomers with asymmetric carbon atoms have been widely used and their chiral copolymers have been studied (6-8), chiral monomers based on atropisomerism (chirality originating from hindered rotation about single bonds which leads to two conformationally stable optical antipodes) have not yet been used in order to obtain chiral copolymers.
This is to the best of our knowledge the first example of the use of atropisomerism in order to induce chirality in copolymers.
