Mentions: One of the interesting emerging properties of supramolecularhost–guestsystems is the stimuli-dependent expansion and contraction of molecularconstructs. This behavior will be revisited in rotaxane systems in section 8. In double-strandedhelicate 52 (bridged by spiroborates at each end), sodiumion-induced reversible extension and contraction was observed withan accompanying directional twisting (Figure 21).589 In thepresence of Na+, the molecule was forced to twist its centraltetraphenol moiety to better coordinate the cation. The handednessof the helicate was preserved during this process. This process couldbe reversed by the sequestration of Na+ by [2.2.1]cryptand.
