摘要
A new kind of neutral carrier is described, binuclear metalloporphyrin, which exhibits the anti-Hofmeister selectivity pattern for anions. A comparison of potentiometric response characteristics between the binuclear and mononuclear metalloporphyrins is discussed in view of the coordination chemistry of metalloporphyrins. The interaction between the ionophore and the analyte anion was investigated by UV/Vis and IR spectroscopy. The transfer process of the analyte anion across the membrane interface was studied by A.C. impedance measurements. The origin of the anti-Hofmeister selectivity sequence was explored by quantum chemical calculations.
