Reproducible switching of the polymorph‐dependent excited‐state intramolecular proton‐transfer (ESIPT) luminescence of an imidazo[1,2‐ a ]pyridine between blue‐green and yellow (see picture) is achieved by thermal control of its solid‐state molecular packing. Thus, ESIPT is a promising mechanism for packing‐to‐luminescence transduction and amplification that offers a novel design concept for tunable organic luminescent solids.
