Reversible switching between order and disorder in a 1‐nonanethiol selfassembled monolayer (SAM) is easily accomplished by alternately exposing the monolayer to liquid ethanol then to a helium stream (see picture). Upon removing the liquid phase, the development of crystalline order in the monolayer takes place over a time scale of hours, which implies the sequential crystallization of individual thiol domains.
