Abstract
Acylhydrazone derivatives N′-[1-(2-fluorophenyl)ethylidene]pyridine-3-carbohydrazide (R1) and N′-[2-fluorobenzylidene]benzohydrazide (R2) were synthesized from their corresponding hydrazides and characterized by spectroscopic methods. The response of these acylhydrazones towards different anions was studied by colorimetric and spectrofluorometric methods in acetonitrile. The receptors exhibited a specific response towards fluoride ion. The binding affinity of the receptors with fluoride anion was studied by fluorescence spectroscopic techniques and ab initio density functional theory calculations with Becker’s three-parameter Lee–Yang–Par (B3LYP) exchange functional with 6-311G basis set.
