Abstract

Novel Hg2+ receptors having two N-benzyloxyamide groups are synthesized, and their complexation ability toward metal cations is examined. The structure of the formed complexes was elucidated by ESI-MS and 1H NMR spectroscopy. Deprotonation of the amide groups allows the receptors to form stable complexes with Hg2+. As an application of this neutral Hg2+ complex, an anion-selective electrode combined with a cationic additive is prepared, and exhibits an anti-Hofmeister selectivity pattern with enhanced selectivity for the iodide anion. The overall selectivity pattern of the electrode is I- > ClO4- > SCN- ≈ Br- > salicylate- > NO2- > Cl- > NO3- ≫ HCO3- > SO42- > F- > H2PO4-.
