The image shows a representative one-handed helical structure of poly(naphthalenecarboxamide) obtained by DFT calculation. On page 739, Koichiro Mikami and Tsutomu Yokozawa present the synthesis and chiral amplification of a helical aromatic polyamide, poly(naphthalenecarboxamide), with alkyl side chains. The helical polyamide is synthesized by means of chain-growth condensation polymerization. The folding of the polymer is exemplified using UV and CD spectroscopy. The copolymer of monomers having a chiral alkyl side chain and an achiral alkyl side chain shows a significant chiral amplification on the basis of the sergeants and soldiers principle in a hydrophobic environment even with only a tiny incorporation of chiral units.
