Electronic Structure-Tuned Solvatochromic Probes for TBET-Driven Ratiometric Detection of Phosgene in Solution and Polymer Films.
Phosgene, a highly toxic industrial chemical, necessitates rapid, reliable, and field-deployable detection technologies because of its widespread industrial use and the risk of accidental release. Herein, we report two ICT-based solvatochromic fluorophores, RHTH-NMe2 and RHTH-NEt2, constructed from rhodamine-thiophene-...
