Vitamin B6 cofactor derived chemosensor for the selective colorimetric detection of acetate anions

A novel Vitamin B6 cofactor derived anion sensor L for the selective colorimetric detection of acetate has been developed by the Schiff base condensation of pyridoxal and 2-aminothiophenol. The anion recognition ability of the sensor L was investigated by spectroscopic (UV-vis and 1H NMR) and DFT methods.
