Abstract: The conformation of copper "funnel" complexes that contains a coordinating appended arm can be electrochemically switched between endo, which corresponds to the self-coordination of the arm through the cavity, and exo positions. This process, which is reminiscent of a cup-and-ball device, is activated by an exogenous ligand for complexes that contain a hydroxy-terminated arm. The exchange is electrochemically triggered and is operated in either Cu(I) or Cu(II) redox states, depending on the exogenous ligand, that is, CO or n-butylamine, respectively.<br /> (Copyright © 2013 WILEY-VCH Verlag GmbH & Co.
