Supramolecular recognition of CWAs simulant by metal-salen complexes: the first multi-topic approach

Sensing of Chemical Warfare Agents is today an important target, mainly due to the international scenario. Here a new approach, based on supramolecular multi-topic recognition of dimethyl methylphosphonate, a simulant of Chemical Warfare agents, is reported. These receptors, based on metal-salen complexes, combine their abilities to establish Lewis Acid-Base interactions and hydrogen bonds and pave the way for the realization of a new class of supramolecular sensors for the non-covalent recognition of Chemical Warfare Agents simulants.
