The　reaction　of　2,2-diferrocenylpropanealkylimidazole　with　sodium　2-bromoethanesulphonate　led　to　the　formation　of　2,2-diferrocenylpropane-　substituted　imidazolium　sulphonate　salt.　All　of　these　compounds　were　characterized　by　IR,　MS,　HRMS,　1H　and　13C　NMR　spectra.　The　anion　binding　studies　were　carried　out　using　various　techniques　such　as　electrochemistry　(cyclic　voltammetry)　and　1H　NMR　spectroscopy.　The　electrochemical　behavior　indicated　that　the　receptor　1　had　unique　selectivities　for　F-　and　H2PO4　-　with　the　remarkable　phenomenon　of　merging　the　two　redox　peaks　in　response　to　the　increment　addition　of　the　anions.　1H　NMR　titrations　demonstrated　that　the　receptor　1　could　bind　anions　in　a　(C-H)+â̄X　-　type　ionic　hydrogen　bonding　and　showed　affinity　and　high　selectivity　for　F-　anion　in　DMSO-d6　on　account　of　the　intensity　of　the　imidazolium　C-H　resonance　decreased　gradually　and　disappeared　along　with　the　increase　of　F-　and　had　a　triplet　around　the　16　ppm　region　for　the　HF2　-　ion,　indicating　deprotonation　and　fluoride　ion　mediated　hydrogen-deuterium　exchanges.　©　2013　Elsevier　B.V.　All　rights　reserved.
