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

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

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,...

Zusammenfassung: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.
