A chameleonic, redox‐switchable carrier molecule: A [4,4]ferrocenophane ligand can selectively recognize Mg 2+ ions through complexation. This ligand can transport and release Mg 2+ ions by application of an external electrochemical stimulus across a CH 2 Cl 2 liquid membrane (see picture). Furthermore, dramatic color changes are seen, which allow the potential for “naked‐eye” detection.
