Rotaxanes and Catenanes in Action,ation state of the copper centre (I or II) entirely determines the set of ligands coordinated to the metal. Oxidizing or reducing the central copper atom thus induces a complete gliding motion of one cycle within the other. This process can be regarded as electrochemically triggerred swinging of the copper catenate.

This supports the presence of the spin frustration.

The intramolecular spin alignment in these systems is based on orthogonality of the singly occupied orbitals either of the one-centered diradical, carbenes, or the .-phenylene diradicals having right topological symmetry [4].
