摘要：

We have found an unprecedented memory of macromolecular helicity induced in an achiral sodium salt of poly(4-carboxyphenyl isocyanide) (poly-1-Na). Poly-1-Na folds into a one-handed helix through configurational isomerization around the C=N backbones by interactions with optically active amines in water. The helix remains when the optically active amines are completely removed, and further modifications of the side group to carboxy and esters can be possible without loss of the macromolecular helicity memory.
