Hooks and feelers : The use of a bulky tripod‐shaped stopper as a solid‐phase attachment point proves essential for the controlled iterative solid‐phase synthesis of an α‐cyclodextrin [3]rotaxane (see picture). NMR spectroscopy confirms the structure and shows that both the cyclodextrin units have well‐defined locations and orientations.
