Redox-controlled self-inclusion of a lasso-type pseudo[1]rotaxane.

The self-inclusion behavior of a tetrathiafulvalene-containing lasso-type pseudo[1]rotaxane can be reversibly switched between threaded and non-threaded states by redox-stimuli. The switching mechanism was investigated by cyclic voltammetry in solution and monitored by ion mobility mass spectrometry in the gas phase.
