Abstract

A 2,4-dinitrophenyl hydrazine appended sensing material has been synthesized and characterized by NMR, IR and HRMS spectral studies. The selective colorimetric sensing property of the chemosensor for F− has been thoroughly investigated with UV–Vis, NMR and DFT analysis. The limit of detection (LOD) and association constant has been found to be 1.37 μM and 3.09 × 107 M−1, respectively. High electronegativity of F− is responsible for hydrogen bonding induced deprotonation of chemosensor and subsequent color change from yellow to pink. Paper strip kit of the chemosensor has been applied successfully for sensing of F−.
