A new chemosensor L has been synthesized using Schiff base reaction of pyridoxal with hydrazine and characterized by various spectroscopic techniques such as FTIR, 1H NMR and mass spectrometry. The anion recognition ability of the synthesized sensor has been investigated by UV-vis, fluorescence and 1H NMR methods. Among the tested anions, the developed sensor shows a naked-eye detectable color change from colorless to red and spectral changes in the presence of fluoride and acetate ions due to the partial deprotonation of the sensor. With a micromolar detection limit, the developed sensor is highly efficient and may be utilised for the colorimetric detection of fluoride/acetate ions. The developed sensor has been successfully fabricated in to the INHIBIT logic gate at molecular level.
