Anion-templated calixarene-based pseudorotaxanes and catenanes.
We present the rational design and anion-binding properties of the first anion-templated pseudorotaxanes and catenanes in which the "wheel" component is provided by a calixarene macrobicyclic unit. The designs and syntheses of two new calixarene macrobicycles, 2 and 3, are presented, and the abilities of these new species both to bind anions and to undergo anion-dependent pseudorotaxane formation are demonstrated. Furthermore, it is shown that performing ring-closing metathesis reaction...Expand abstract
