Abstract
A simple colorimetric anion chemosensor based on 2-amino-6-nitrobenzothiazole was synthesized. The addition of tetrabutylammonium (TBA) salts of <TEX>$F^-,\;{CH_3COO}^-,\;and\;{H_2PO_4}^-$</TEX> to the solution of receptor 3 caused dramatic and clearly observable color changes from light to dark yellow due to the deprotonation process which is totally different from previously reported receptors based on the same motif. According to the basicity of the anions, the sensitivity of receptor 3 towards various anions decreased in the following order: <TEX>${CH_3COO}^-\;>\;F^-\;>\;{H_2PO_4}^-$</TEX>.
