✦ Synopsis
Non-ionic template effects [1] proved to be a successful concept to synthesize supramolecular architectures [2], especially hydrogen bond-mediated catenane [3] and rotaxane [4] formation [5].
In the beginning aromatic diacid dichlorides were believed to be the guests to fit into tetralactame macrocycles. Reaction with bulky amine stoppers in the presence of a macrocycle led to amide-based rotaxanes. Yet by replacing the aromatic diacid dichloride "guests" with aliphatic ones it was even possible to synthesize amidebased rotaxanes with aliphatic building blocks [6]. So
