  • Supramolecular machines: double translocation by electron input for ditopic heterometallic Cu,Zn complexes:

The driving force of the translocation is the electrochemical switch of the copper cation between oxidation states I and II coupled with the balance between the preferential coordinating mode of the ditopic ligand for the two pairs Zn(II)/Cu(I) and Zn(II)/Cu(II).
