Rapid ‘naked eye’ response of DCP, a nerve agent simulant: from molecules to low-cost devices for both liquid and vapour phase detection

Abstract

A rhodamine-based new chemosensor, RHM, has been designed and synthesized. It reacts selectively with the organophosphate compound, DCP, a well-known nerve gas simulant (both in the liquid and vapour phase). Moreover, RHM offers the potential for detection by the naked eye for color and fluorescence change. The sensing phenomenon is supported by DFT calculation.
