A conformational analysis of three triazole‐containing bridged bis‐β‐cyclodextrins has been carried out to evaluate their recognition ability. In their Full Paper on page 3949 ff. , E. Monflier et al. demonstrate that one of the cyclodextrin glucopyranose units undergoes a 360° rotation in water so that the spacer linking the two cyclodextrins is included deep within one of the cyclodextrin cavities. The evidence of the tumbling is of crucial importance because it allows for a better understanding of the supramolecular recognition abilities of these compounds.
