A　new　anion　receptor　that　utilized　boron-fluoride　interaction　and　(C-H)(+)...F--type　ionic　hydrogen　bonding　in　the　binding　of　F　ions　had　been　synthesized　and　characterized　by　IR,　MS,　HRMS,　B-11,　H-1,　and　C-13　NMR　spectra.　The　signaling　process　was　confirmed　by　UV-vis,　electrochemistry　measurements　as　well　as　H-1,　F-19,　and　B-11　NMR　spectroscopy.　Among　the　tested　anions:　F-,　Cl-,　Br-,　OAc-,　H2PO4-,　HSO4-,　only　F-induced　a　remarkable　red-shift　(29　nm)　in　the　absorption　spectrum　which　was　concomitant　with　a　color　change　from　pink　to　faint　yellow.　This　receptor　provided　a　new　approach　for　naked-eyed　detection　of　F-　and　the　detection　limit　was　calculated　to　be　1.26　mu　M.　Besides,　Cyclic　Voltammetry　(CV)　showed　that　the　receptor　had　unique　selectivities　for　F-　with　a　remarkable　phenomenon　in　merging　of　the　two　reduction　peaks　in　response　to　the　increment　addition　of　the　anions.　H-1,　F-19,　and　(11B)　NMR　titration　demonstrated　that　the　receptor　showed　affinity　and　high　selectivity　for　F-　and　provided　the　evidence　of　interaction　between　the　receptor　and　F-.　(C)　2016　Elsevier　Ltd.　All　rights　reserved.
