No2 Detection

A new fluorescent chemodosimeter for detecting NO2 has been synthesized. The sensing mechanism is based on the regeneration of the carbonyl group induced by the target molecule. This reaction gives rise to both colorimetric and fluorescent changes. A LOD of 0.1 ppm has been determined.

Fluorescent Chemodosimeter

A smart ratiometric red fluorescent chemodosimeter (AH) has been explored for specific detection of F− with a lowest detection limit of 3.45 × 10−10 M. The sensing mechanism was worked out as fluoride-triggered deprotonation of imidazole accompanied by deprotection of the nosylate group.
