Transition metal ions can be moved reversibly between the two coordinatively unequivalent compartments A and B of a ditopic ligand, using as an input the variation of a bulk solution parameter, either pH or redox potential. In a redox-driven translocation, the metal moves reversibly from A to B on cycling between two consecutive oxidation states (e.g., CuII/CuI; FeIII/FeII) by means of auxiliary oxidation and reduction reactions. In a pH-driven process, one compartment displays also acid−base properties (AHn An- + nH+), and the Mn+ ion is translocated between B and An- through consecutive addition of base and acid.

Abstract

Transition metal ions can be moved reversibly between the two coordinatively unequivalent compartments A and B of a ditopic ligand, using as an input the variation of a bulk solution parameter, either pH or redox potential. In a redox-driven translocation, the metal moves reversibly from A to B on cycling between two consecutive oxidation states (e.g., CuII/CuI; FeIII/FeII) by means of auxiliary oxidation and reduction reactions. In a pH-driven process, one compartment displays also acid−base properties (AHn An- + nH+), and the Mn+ ion is translocated between B and An- through consecutive addition of base and acid.
