Hi,, To test the selectivity of a molecular chemosensor toward anions, Tetrabutylammonium salts are used, is it okay to use other salts for the same anions, for example is it okay to use sodium acetate instead of tetra-n-butylammonium acetate?

It's perhaps due to the solubility difference and polarity as in comparison. I think the binding processes with the anions are fast and reversible. However, the anion chemosensors operate by a deprotonation mechanism of the central N–H proton rather than by hydrogen bonding as is often reported.
