“…This is favorable for seeking a chirality linkage among the hierarchical structures in universe [54,55], where supramolecular chirality in crystals are significant as one of the expression of molecular information [3,4,8,10]. The 21 helical columns seem to be analogous to 3D building-bricks in daily life, inducing a delightful research in crystal engineering toward creation of chiral materials, including organic, inorganic and polymeric compounds, starting from achiral components.…”
