Water-recyclable and reusable fluorescent sensors for nerve gas mimetic detection†
Herein, the serendipitous discovery of two water-recyclable and reusable fluorescent sensors IMPC (cyan–blue–cyan) and IMPC-OH (green–blue–green) is reported for sensing nerve agent simulants diethylcyanophosphonate and diethylchlorophosphate, respectively, with high sensitivity, short response time, and low detection limits. The unique features of these probes are their regeneration with the addition of a green and cheap solvent, namely water in CHCl3, and ease of fabrication into a portable paper-strip system that can also be regenerated. Various spectroscopic studies were employed to understand the mechanism of sensing and regeneration of both probes; the results reveal that water plays a critical role in the hydrolysis of the adduct formed with DCNP and DCP, which enables the retrieval of the probe with its original fluorescence.
