Dynamers in action can be observed with responsive supramolecular architectures on surfaces. In their Communication on page 1963 ff., G. P. Spada, P. Samorì, and co‐workers report how scanning tunneling microscopy was used to achieve submolecular‐scale visualization of the metal‐templated reversible assembly/reassembly process of N 9 ‐alkylguanine monolayers. Changes in pH switch the resulting structures from highly ordered quartets to ribbons.
