Mercapto Thiadiazole-Based Sensor with Colorimetric Specific Selectivity for AcO- in Aqueous Solution
A novel acetate selective anion sensor 3 based on azophenol and mercapto thiadiazole had been designed and synthesized. Sensor 3 behaves a single selectivity and sensitivity in the recognition for AcO* anion over other anions such as F‐, C1‐ Br‐, I‐, H2PO4‐, HSO4‐ and CIO4‐ by naked-eyes and UV-vis spectra changes in aqueous solution (H2O/DMSO, 5:5, v/v). 1H NMR titration results revealed that the binding process includes two steps: (I) hydrogen bonding interactions (for small quantities of acetate) and (ii) proton transfer between the sensor 3 and the coordinated anion (for high quantities of acetate).
