Abstract A series of xylyl ( ortho , meta , and para ) linked N -ferrocenylmethylene-substituted bis-imidazolium salts ( 3a–3c ) and bis-benzimidazolium salts ( 4a–4c ) were synthesized and structurally characterized. Their binding properties for anions were investigated by electrochemistry and 1 H NMR spectroscopy. The structure of 3b , 3c , 4a and 4b were confirmed by X-ray crystallography. As expected, all salts were good electrochemistry-signaling receptors for several anions (F − , AcO… Expand
