Changed in a flash : A photochemically unreactive crystal of 5‐methyl‐2‐pyridone with a trimesic acid host is transformed in the solid state into a reactive phase by heating or by contact with solvent vapor. The mechanism was revealed to involve desolvation and a 180° turn of one molecule with respect to the other.
