Tetrathiafulvalene cyclophane based

It is widely known that tetrathiafulvalene (15) - commonly known as TTF -can be easily oxidized to its radical cation and then on to its dicationic state. Previous research [36] from our laboratories had shown that reduction of the tetracationic cyclophane CBPQT4+ reduces enormously its binding affinity for 7i-electron-rich guests. In the light of this knowledge, it was considered possible to develop a pseudorotaxane-based switch in which the switching process is not only controlled and monitored electrochemically, but in which it can be accomplished [37] in one of two ways.
