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,　H-1　and　C-13　NMR　spectra.　The　anion　binding　studies　were　carried　out　using　various　techniques　such　as　electrochemistry　(cyclic　voltammetry)　and　H-1　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.　H-1　NMR　titrations　demonstrated　that　the　receptor　1　could　bind　anions　in　a　(C-H)(+)center　dot　center　dot　center　dot　X-　type　ionic　hydrogen　bonding　and　showed　affinity　and　high　selectivity　for　F-　anion　in　DMSO-d(6)　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.　(C)　2013　Elsevier　B.　V.　All　rights　reserved.
