Concave versus Planar Geometries for the Hierarchical Organization of Mesoscopic 3D Helical Fibers

Concave versus Planar Geometries for the Hierarchical Organization of Mesoscopic 3D Helical Fibers

Chromophore–peptide systems: A study on a series of pentapeptides covalently connected to planar π systems (1 a and 1 b) or to a curved π system (1 c) showed the influence of the concave shape on the efficient chiral transmission at nano‐ and mesoscales. Control over the hierarchical growth by H bon...

Zusammenfassung:Chromophore–peptide systems: A study on a series of pentapeptides covalently connected to planar π systems (1 a and 1 b) or to a curved π system (1 c) showed the influence of the concave shape on the efficient chiral transmission at nano‐ and mesoscales. Control over the hierarchical growth by H bonding, π–π, and solvophobic interactions made possible the efficient generation of electroactive 3D helical fibers (see picture).
