Abstract

original image

A commodity plastic, syndiotactic poly(methyl methacrylate) (st-PMMA), has been found to fold into a right- or left-handed helix through the assistance of (R)- or (S)-1-phenylethanol (1) and encapsulates fullerenes within its helical cavity to form a robust, processable, and optically active peapod-like complex whose helicity is retained after removal of the chiral alcohols.
