Tunable cyclic operation of dissipative molecular switches based on anion recognition
CHEMICAL COMMUNICATIONS(2024)
摘要
Artificial dissipative molecular switches based on anion recognition are of great importance to simulate biological functions and construct smart materials. Five activated carboxylic acids are used as chemical fuels for dissipative molecular switches, which consist of an imidazolium macrocyclic host and a carboxylate anionic guest. By choosing different types of chemical fuels and using varied fuel concentrations, the rates of cyclic operations are tunable. The operation is capable of undergoing at least three cycles. Chemical fuel-driven anion recognition-based dissipative molecular switches with tunable kinetics are designed and investigated.
