Hydrogel Lasers Via Supramolecular Host–Guest Complexation

Advanced Optical Materials, 2023
AbstractSupramolecular host–guest complexes are dynamic systems composed of typically macrocyclic host molecules encapsulating smaller guest molecules. One of their applications is the selective encapsulation of fluorescent dye molecules to tackle quenching and photobleaching in solution.

Transient host-guest complexation to control catalytic activity

Journal of the American Chemical Society, 2022
Signal transduction mechanisms are key to living systems. Cells respond to signals by changing catalytic activity of enzymes. This signal responsive catalysis is crucial in the regulation of (bio)chemical reaction networks (CRNs). Inspired by these networks, we report an artificial signal responsive system that shows signal-induced temporary catalyst ...
