Quantifying the working stroke of tetrathiafulvalene-based electrochemically-driven linear motor-molecules

Sune Nygaard, Bo W. Laursen, Amar H. Flood, Camilla N. Hansen, Jan O. Jeppesen and J. Fraser Stoddart

A highly constrained [2]rotaxane, constructed in such a way that the tetracationic cyclobis(paraquat-p-phenylene) ring is restricted to reside on a monopyrrolotetrathiafulvalene unit, has been synthesised and characterised. This design allows the deslipping free energy barrier for the tetracationic ring in all three redox states of the rotaxane to be determined.
