Abstract

The assembly of molecular Borromean Rings from constitutionally independent rings in a stepwise manner depends on the preparation of robust "gring-in-ring" complexes. The π-electron rich macrocycle bis-1,5-dinaphtho[50]crown-14(1) is shown to form 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.
