Anions　are　ubiquitous　in　the　world　and　play　important　roles　in　modern　chemistry　and　life　process,　numerous　efforts　have　been　devoted　to　the　design　of　acyclic　receptors　capable　of　selectively　binding　and　sensing　anions.　Herein,　several　novel　trinuclear　ferrocene-based　imidazole　receptors　2a-2c　were　synthesized　from　the　reactions　of　1-(ferrocenylmethylene)　imidazole　with　corresponding　bromides　1a-1c.　All　of　these　receptors　were　characterized　by　1H　NMR,　13C　NMR,　MS,　IR　and　elemental　analysis.　The　anion　binding　studies　were　carried　out　by　various　techniques　such　as　electrochemistry　(CV　and　DPV)　and　1H　NMR　spectroscopy.　Electrochemical　behavior　indicated　that　all　the　receptors　displayed　unique　electrochemical　sensing　property　for　F-　with　a　remarkable　phenomenon:　the　previous　peak　of　the　free　receptor　gradually　diminished,　a　new　wave　at　more　negative　potential　(ΔEp>-150　mV)　appeared　due　to　the　hydrogenation　reaction.　1H　NMR　titrations　demonstrated　that　all　the　receptors　could　bind　anions　through　(C-H)+…anion　hydrogen　bonds　forming　1:1　stoichiometric　complexes　and　had　good　fluoride　binding　ability　in　DMSO-d6.　Addition　of　F-　caused　deprotonation　effect　on　the　receptors,　indicating　the　receptors　showed　better　affinity　for　F-.　Particularly,　receptor　2b　turned　out　to　be　a　very　good　anion　receptor　with　remarkably　high　preference　in　binding　with　F-.　©,　2015,　Higher　Education　Press.　All　right　reserved.
