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.

Colors and Magnetism
When atoms or molecules absorb light at the proper frequency, their electrons are excited to higher-energy orbitals. For many main group atoms and molecules, the absorbed photons are in the ultraviolet range of the electromagnetic spectrum, which cannot be detected by the human eye. For coordination compounds, the energy difference between the d orbitals often allows photons in the visible range to be absorbed and emitted, which is seen as colors by the human eye.
