A stable tetrathiafulvalene (TTF) functionalized self-assembled monolayer has been fabricated from compound 3. The electrochemical adjustment of the guest properties of the TTF moiety of this unit has facilitated the development of surfaces in which the 30 state forms a pseudorotaxane with the electron deficient macrocyclic host cyclobis(paraquat-p-phenylene) 1, and the electrochemically generated dicationic state 32+ forms a pseudorotaxane with the electron rich macrocyclic host 1,5-dinaphtho[38]crown-10 2.
