Fluorescence sensing of anions has attracted continuing interest given that a variety of anion molecules are involved in chemical and biological systems. A number of fluorescence anion sensors have been developed based on different disciplines in the sensor design. However, the development of fluorescence turn–on type sensing systems for anions of biological importance remains as a challenging issue, because in many cases fluorescence quenching rather than enhancement results. Recently, we have demonstrated that introduction of a H-bonding donor such as carboxamide or sulfonamide group at ortho position to the trifluoroacetyl group stabilizes the anionic adducts and thus enhances the association constant toward anions such as carboxylates to a useful level. This H-bonding stabilization approach enabled us to introduce novel fluorescent, colorimetric, and electrochemical probes for cyanide, carboxylates, and dicarboxylates. Herein, we wish to disclose some of our recent results obtained from the recognition and sensing of amino carboxylates.
