Anion detection through control and activation of halogen bonding triggering by electrochemistry

Séminaire du Dr Claire Fave (LEM UR 7591, Université de Paris)

Abstract :

Non-covalent interactions are crucial and of increasing interest in “supramolecular electrochemistry” concerning redox properties of supramolecular assemblies in solution. The importance of halogen bonding, an only recently described non-covalent interaction, is nowadays fully recognized. In this context we have shown the electrochemically triggered switching of halogen bonding in solution and at the electrode/electrolyte interface. The observed high sensitivity for chloride detection is a promising finding considering fundamental understanding of reactivity issues as well as potential applications of the concept for the future development of novel selective anion sensors, capture/release systems and organocatalysis.
