Figure 5
(a) Schematic representation of right- or left-handed helix formation in the C60-encapsulated st-poly(methyl methacrylate) (PMMA) supramolecular assembly induced by R- or S-phenylethanol (1). The macromolecular helicity was maintained even after the removal of the chiral dopant. Adapted from Kawauchi et al.59 (2008 Wiley-VCH). (b) Schematic representation of the formation of macromolecular helicity in the copolymer with a fullerene pendant induced by complex formation between a crown ether and L-alanine. A chiral crown ether and a fullerene were arranged in helical arrays with the screw-sense along the backbone of the polymer. Adapted from Nishimura et al.64 (2004 RSC).
