A family of three molecular shuttles based upon ammonium/triazolinium salt motifs with one, two, and three catalytic centers were prepared along with their corresponding non-interlocked threads. The switching process for all rotaxanes was tested through an in situ procedure in solution. Furthermore, their organocatalysis of two Michale-type reactions by iminium activation was tested to check whether the increase of the number of catalytic centers in the same shuttle is a decisive factor to improve their efficiencies compared with those of single-active-site organocatalytic shuttles under the same conditions.

Switch it on! The activity of an organocatalytic group incorporated within a rotaxane architecture can be controlled by switching the position of the macrocycle. The system was used to mediate the progress of the Michael addition of an aliphatic thiol to trans-cinnamaldehyde. Copyright
