✦ Synopsis

Helices and superhelices are key structural features of proteins, nucleic acids, and oligosaccharides. It is therefore no surprise that helical structures and superstructures have received increasing attention in biomimetic and synthetic supramolecular systems. [1] Helical organization in synthetic systems has been obtained through covalent conformational restrictions, metal complexation, [3] solvophobic effects, intermolecular interactions, [5] and nonbonding intramolecular interactions. [6] Several approaches to the generation of helical entities have been pursued in our group starting from double-helical metal complexes (helicates), [8] followed by triple helicates, [9] circular helicates, and helically wound, supramolecular liquid crystalline polymers.
