An Electroactive Nitrogen‐Rich [4.4]Ferrocenophane Displaying Redox‐Switchable Behavior: Selective Sensing, Complexation, and Decomplexation of Mg²⁺ ions

Abstract

A chameleonic, redox-switchable carrier molecule: A [4,4]ferrocenophane ligand can selectively recognize Mg2+ ions through complexation. This ligand can transport and release Mg2+ ions by application of an external electrochemical stimulus across a CH2Cl2 liquid membrane (see picture). Furthermore, dramatic color changes are seen, which allow the potential for “naked-eye” detection.
