文摘

Macroscopic continuous hierarchical ordering of achiral nanotube “imogolite” was achieved by thixotropic gelation of imogolite with chiral hydroxy acid and their flow-orienting/subsequent standing for uniaxial alignments of imogolite. The chirality change of the hydroxy acids resulted in an inversion of the helical ordering. The study presented here first exhibits the millimeter-scale supramolecular chirality induced by angstrom-scale molecular handedness in the architecture of nanotubes.
