The assembly of molecular Borromean Rings from constitutionally independent rings in a stepwise manner depends on the preparation of robust “ring-in-ring” complexes. The π-electron rich macrocycle bis-1,5-dinaphtho[50]crown-14 (1) is shown to form a donor-acceptor ring-in-ring complex with the π-electron poor cyclophane cyclobis(paraquat-4,4'-biphenylene) (24+) in solution. In the crystal superstructure of [1⊂2]·4PF6, CH···O interactions between the polyether loops of 1 and the bipyridinium units of 24+ could disfavor the threading of dialkylammonium components of a third ring.

12. Calculations were carried out using Schrödinger MacroModel v9.6. A structural model of [1⊂2]·4Cl was built based on a related crystal structure of a [5]catenane [13] which has two dioxynaphthalene units encompassed by 24+. A conformational search using OPLS carried out in water showed that the polyether loops were of appropriate size to bind a dialkylammonium cation.
