Abstract:Optically active left (M)‐ and right (P)‐handed helical syndiotactic poly(methyl methacrylate)s (M‐ and P‐st‐PMMAs) with a helicity memory enantioselectively encapsulated the racemic C60 derivatives, such as 3,4‐fulleroproline tert‐butyl ester (rac‐1) and tetraallylated C60 (rac‐2), as well as the C60‐bound racemic 310‐helical peptides (rac‐3) within their helical cavities to form peapod‐like inclusion complexes and a unique “helix‐in‐helix” superstructure, respectively. The enantiomeric excess (ee) and separa… Show more
