Supramolecular complexation of perylene bis(diimide) (PDI) dyes with the macrocyclic host cucurbit[8]uril (CB[8]) prevents self‐aggregation of the dye molecules and enables their use as highly (photo)chemically stable, strongly‐emitting fluorophores in water. The complexes are stimuli‐responsive to binders and can be electrochemically cycled, leading to reversible on–off fluorescence switching and access to noncovalent formation of higher‐order architectures in water.
