A new neutral receptor containing 2-aminobenzimidazole moieties was synthesized. The binding properties of the host 1 toward dicarboxylates and mono anions have been examined by using fluorescence spectrometry. The host 1 effectively recognized malonate, succinate, glutarate, adipate, and pimelate with 1:1 binding through hydrogen bonding interactions, and it also recognized acetate with 1:1 binding.
