A Highly Selective Chemosensor for Naked-Eye Detection of Fluoride and Aluminium(iii) Ions Based on a New Schiff Base Derivative

A Highly Selective Chemosensor for Naked-Eye Detection of Fluoride and Aluminium(iii) Ions Based... A new chromogenic receptor, 4-((2,4-dichlorophenyl)diazenyl)-2-(3-hydroxypropylimino)methyl)phenol, has been designed and synthesized for quantitative and low-cost detection of various biological anions and cations. The dye was characterized by elemental analyses, infrared, UV-visible spectroscopy, and NMR spectroscopy. The chemosensor showed visual changes towards anions, such as F and H2PO4, in DMSO and towards cations, such as Al3, Cu2, Fe3, and Cr3, in DMSO/water (9:1). The anion recognition property of the receptor via proton transfer was monitored by UV-visible titration and 1H NMR spectroscopy. The binding constant (Ka) and stoichiometry of the hostguest complexes formed were determined by the BenesiHildebrand (BH) plot and Job's method, respectively. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Australian Journal of Chemistry CSIRO Publishing

Abstract

A new chromogenic receptor, 4-((2,4-dichlorophenyl)diazenyl)-2-(3-hydroxypropylimino)methyl)phenol, has been designed and synthesized for quantitative and low-cost detection of various biological anions and cations. The dye was characterized by elemental analyses, infrared, UV-visible spectroscopy, and NMR spectroscopy. The chemosensor showed visual changes towards anions, such as F and H2PO4, in DMSO and towards cations, such as Al3, Cu2, Fe3, and Cr3, in DMSO/water (9:1). The anion recognition property of the receptor via proton transfer was monitored by UV-visible titration and 1H NMR spectroscopy. The binding constant (Ka) and stoichiometry of the hostguest complexes formed were determined by the BenesiHildebrand (BH) plot and Job's method, respectively.
