Freed at the flick of a photoswitch : An acyl hydrazone forms supramolecular assemblies upon the binding of specific salts, such as potassium thiocyanate. This process presents cation and anion selectivity as well as thermo‐ and photoreversibility (see scheme). In particular, the system displays photorelease of potassium cations and undergoes dynamic component exchange in the acyl hydrazone.
