| Abstract: | We report here a selective, efficient and very simple receptor which can easily detect F? in the presence of a wide range of other anions Cl?, Br?, I?, HSO 4 ? , NO 3 ? , Acetate (AcO ?) and Benzoate (BzO ?)] by use of colorimetric or fluorometric detection. 4-Chloro-2,6-bis(hydroxymethyl) phenol (CBHMP) is a simple and available phenolic receptor having no special chromophoric function. In this colorimetric method, naked-eye detection of F? with CBHMP is described. Interestingly, fluorometric detection of F? is also possible by highly selective fluorescent quenching response CBHMP in dimethyl sulfoxide (DMSO) media. |
