A novel indole Hydrazone receptor 1 has been synthesized by one step of condensation, which can act as an efficient colorimetric and turn on fluorescent sensor for fluoride anions; Benesi-Hildebrand equation indicates that 1 associates with F- in a 1:1 stoichiometry; [TBA]OH and H-1 NMR titration experiments indicate that the deprotonation process involved upon addition of fluoride anions.
