Condensation of Pyridine carboxaldehydes with aminophenol and related compounds have been synthesized and characterized by Spectroscopic methods such as NMR and IR. The generated Schiff bases optical properties were determined. They were investigated as chemical sensors for detection of variety of anions. They showed high colorimetric and optical selectivity towards basic and nucleophilic anions. The selectivity was tuned by solvent choice. High selectivity towards cyanide was observed in aqueous media. Visual detection and spectroscopic titrations were used to determine the binding constants and their high selectivity and detection ability towards specific anions. The synthesis and their properties as chemical sensors will be presented.
