Abstract

Concentration-dependent dynamically equilibrating systems play a crucial role in biology, supramolecular assemblies, and materials science. Herein, host-guest interaction triggered fluorescence emissions have been exploited to monitor concentration-dependent superstructures including a supramolecular polymer and dimers in aqueous solution. Given the unique photophysical properties associated with the dye guest in the cucurbit [8]uril-based rigid confined cavity, the resulting host-guest interactions exhibited unprecedented concentration-dependent dynamic assemblies. These can be clearly distinguished by multiple fluorescence emissions and by the naked-eye under UV-light. This work provides new insight for designing and characterizing dynamic equilibria in host-guest chemistry and materials science.
