Detection and remediation of organophosphorus compounds by oximate containing organogels

Abstract

A series of supramolecular diamide organogels containing a reactive compound for the remediation of organophosphorus (OP) species, in particular OP chemical warfare agents (CWAs), has been prepared in DMSO. The organogels have been found to absorb, encapsulate and decontaminate various OP CWA simulants in situ. At high simulant concentrations the gels also undergo a gel–sol transition releasing high local concentrations of remediation agent.
