Strongly fluorescent, switchable perylene bis(diimide) host-guest complexes with cucurbit[8]uril in water.
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.
