A Diagram of a fish trap. Fish can get in through the wide part of the funnel-like door, but cannot get out. B Scanning tunneling microscopy image of a supramolecular architecture from a non-centrosymmetric hexagonal unit cell of cyano-functionalized triarylamines showing zigzag edges. C Supramolecular nanoribbon with zigzag boundaries and periodic in y direction. D Section of the nanoribbon depicting a phononic edge state as eigenvector intensity map. E Molecular dynamics simulations are employed to excite edge-localized phonon modes, which unidirectionally propagate along the edge. All scale bars measure 1 nm. Copyright: Matters of Activity
