Colorimetric sensing of anions by a neutral biphenyl based amide receptor

subject

Biphenyl Chemistry Ligand Organic Chemistry Inorganic chemistry Halide Photochemistry lcsh:QD241-441 chemistry.chemical_compound Deprotonation lcsh:Organic chemistry Amide Receptor Fluoride Stoichiometry

description

A new colorimetric sensor for fluoride is described. Compound 1 shows an open structure and its behaviour is compared with that of two related closed compounds 2 and 3. In all cases, the red colour developed in the presence of fluoride can be related to deprotonation processes, however ligand 1 gives rise to a faster colour change than 2 or 3 because of its higher flexibility. Other halides as well as carboxylates have been studied and the stoichiometry and complexation constants for the corresponding ligands have been determined.
