Abstract

Abstract: Two structurally simple rhodanine-based derivatives were synthesized and their UV-vis absorption spectra responses(in CH₂Cl₂-DMSO) on anions were examined.It was found that only fluoride can lead to remarkable spectrum changes.Job’s plot indicates a 1:1 stoichiometric relation between receptors and fluoride,which was also confirmed by ¹H NMR titration.The interaction mode between fluoride and receptors may be attributed to either hydrogen bonding or deprotonation.

Key words: rhodanine, anion recognition, fluoride
