Abstract

Abstract: Macroscopic enantiomerically pure helical supramolecular fibers are bottom‐up assembled in aqueous media from a chiral π‐electron donor template and an achiral π‐electron acceptor. The helices can be assembled to the sub‐millimeter scale with controlled handedness. These dynamic supramolecular architectures allow for a quantitative exchange of the chiral donor template with achiral analogues. During this process, a chiral memory effect was observed, affording enantiomerically pure helices composed entirely of achiral components.
