Capsular heterodimers are formed exclusively from a tetra(tosylurea)calix[4]arene (blue) and tetrakis(3,5‐dibutenyloxyphenylurea)‐ or tetrakis(dipentenyloxyphenylurea)calix[4]arenes (red). Metathesis between the prearranged alkenyl groups and subsequent hydrogenation leads to mechanically interlocked capsules which can neither dissociate nor release the included guest(s) owing to their fourfold [2]rotaxane structure.
