A Selective Fluorescent and Colorimetry Competition Assay for Fluoride Ions in DMSO Media Based on 4-Chloro-2,6-bis(Hydroxymethyl) Phenol~1

摘要

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.
