Frustrating: A sterically unencumbered aniline base (see picture, left) can be transformed into a bulky Lewisbase by converting it into a [2]rotaxane (right). This Lewisbase donor, which is surrounded by a protective macrocyclic ring, exhibits the reactivity of a frustratedLewis pair (e.g. activation of H2(g)) without the need for direct covalent modification to increase its bulk.
