Among molecular chiralities, a "rotaxane chirality" recognized in rotaxanes consists of unsymmetric components is of special scientific interest. The rotaxane chirality that comes from difference in component's topology, orientation, or interpenetration is based on an "intercomponent" restriction, and can be distinguished from ordinary molecular chiralities. The rotaxane chirality based on an intercomponent restriction would have unique properties owing both to its dynamic mobility of components and switching function. In this study to clarify the essence of rotaxane chirality we evaluated the ability and significance of their asymmetric field on the chirality induction to polyacetylene helix.
