Abstract
Left‐handed‐helical nanoropes are formed from higher‐order self‐assemblies of chiral aggregates during the gelation of a rigid π‐conjugated oligo(p‐phenylenevinylene) with remote chiral handles (see picture; R=C12H25). The concentration‐ and temperature‐dependent CD‐signal changes observed for these assemblies are indicative of a helix transition. This process is reminiscent of the folding and unfolding of helical biological macromolecules.
