Three acylhydrazone-based compounds were designed as novel neutral sensors for anions, and synthesized by simple steps in good yields. Their anion recognition properties were studied by UV-vis and 1H-NMR spectroscopy. The results showed that the receptors 1, 2, and 3 all had a better selectivity for F- and CH 3 COO -, but no evident binding with Cl- , Br - , 1- , NO 3- , H2 PO4- , or HSO4- .The results indicated that anion recognition was achieved via convergent hydrogen bond interactions from acylhydrazone functionality on the side arms. The UV-vis data indicated that a 1:1 stoichiometry complex was formed between compounds 1 , 2, or3 and anions. The binding and selectivity were also tuned by the change of the place of the nitro group attached to the phenyl. Moreover, receptor 3 can act as the colorimetric sensor for such anions as F - and CH 3 COO - , and the recognition mechanism and binding mode were discussed. TUeBITAK.
