Chemical Modification of a [2]Rotaxane Composed of Dithiacrown Ether and Dialkylammonium with Organic and Inorganic Compounds
The complexation of Pd with dithia[24]crown-8-ether (DTC) and decomplexation by PPh3 addition led to reversible shuttling of the [2]rotaxane, which is composed of DTC and dialkylammonium whose shuttling behavior is different from that induced by N-acetylation of the ammonium moiety of the axle component causing irreversible structural change.
