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.
聚对苯二甲酰亚胺（PDI）染料与大环主体葫芦脲（CB[8]）的超分子络合可防止染料分子的自聚集，并使其能够在水中用作高度（光）化学稳定、强发射荧光团。这些配合物对配体具有刺激响应性，并可进行电化学循环，从而实现荧光开关的可逆开启和关闭，以及在水中非共价形成更高阶结构。
