Naked-eye detection of inorganic fluoride and acetate ion in an aqueous medium using organic receptor: Real life application

Abstract

A new colorimetric chemosensors R was designed and synthesized for the recognition of biological important anions. The binding mode of R was analyzed by colorimetric, and UV-visible. Receptors R1 showed color changes from pale yellow to orange and pale yellow to wine red in the presence of fluoride and acetate ions in DMSO. In addition, receptor R showed high selectivity towards sodium salts of fluoride and acetate ion in an aqueous medium. Moreover, the designed receptor Ralso revealed highly promising results for the quantitative detection of fluoride in real samples like sea water, toothpaste, and mouthwash.
