Luminescent Europium(III) “Turn-On” Sensor for G-Series Chemical Warfare Simulants: A Mechanistic Investigation
Kritika Gupta, Ashis K. Patra
Abstract
A thermodynamically stable terpyridine-dicarboxylate based emissive Eu(III) probe, [Eu(OH-TPDC)] (1), was designed as a time-resolved “turn-on” luminescent probe for the selective sensing of diethyl chlorophosphate (DCP), a G-series nerve agent simulant through modulation of sensitization of 5D0 → 7FJ transitions from Eu(III) via quenching of nonradiative vibrational energy transfer.
