| Spanish abstract | El ensamblaje por pasos de Anillos Borromeos moleculares a partir de anillos constitucionalmente independientes depende de la preparación de complejos robustos "ring–in–ring". El macrociclo rico en electrones n bis–1,5–dinafto[50]corona–14 (1) forma en solución un complejo "ring–in–ring" donador–aceptor con el ciclofano pobre en electrones π ciclobis(paracuat–4,4'–bifenileno) (24+). En la superestructura cristalina de [12]·4PF6, las interacciones CH···O entre los lazos poliéteres de 1 y las unidades bipiridinio de 24 +pueden desfavorecer el enhebrado de componentes dialquilamonio de un tercer anillo |
| English abstract | 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 [12]·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 |
