Terpyridine–Lanthanide Complexes Respond to Fluorophosphate Containing Nerve Gas G‐Agent Surrogates

The significant problem of nerve gas poisoning requires new methods of detection that are sensitive and selective. A new G-type agent chemical sensor is reported that exploits terpyridine–lanthanide emission (see graphic). A detection limit of 6 ppb is obtained and the selectivity for reactive surrogates over a variety of other close chemical analogues is demonstrated.
