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.
