A crystal‐to‐crystal phase transformation of organic cocrystals in response to multiple external stimuli, such as solvent vapor and heating, accompanied by reversible luminescence switching is described by B. Xu and co‐workers in their Communication on page 15098. The results indicate that the luminescence switching originates from the unique molecular rearrangement of a hydrogen/halogen‐bond‐directed stack into a π–π‐interaction‐directed stack in response to an external stimulus.
