The weak‐link approach is illustrated by the reaction of hemilabile phosphinoalkyl thioether ligands that contain incorporated pyromellitic and naphthalene diimide moieties with [Cu(CH 3 CN) 4 ]PF 6 or [{Rh(norbornadiene)Cl} 2 ]. As a consequence, the two diimide units become cofacially aligned, as shown in the cover picture, within a supramolecular macrocyclic architecture. The introduction of ancillary ligands to the intermediates causes the weak thioether–metal bonds to break, thus generating a large macrocycle in which the distance between diimide units is significantly larger than for the intermediates.
