The availability of sodium ions can be regulated indirectly (through electron transfer reactions) and reversibly through the addition and removal of zinc ions. In this cyclic process (depicted on the right) a redox‐responsive ferrocene substituted with two dipicolylamino ligands (Fcdpa) coordinates two Zn 2+ ions, while a redox‐switchable ferrocene cryptand (Fccrypt) only forms stable complexes with Na + when the ligand is in its reduced form. L is a strong ligand such as 1,4,8,11‐tetraazacyclotetradecane.
