Luminescent Supramolecular Assemblies Gold(III) thiolates supported by pyrazine‐based C^N^C pincer ligands show a variable photoluminescent behaviour that depends strongly on the type of pyrazine π‐stacking. Different types of π‐stacking lead to crystal polymorphs, but are also present in solution. Red emissions occur from a dimeric excited state, while monomeric or weakly stacked molecules give green emissions. The image illustrates that this π‐stacking is reversible, so that the emissions can switch between red and green.
