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).
