[3]Rotaxanes with two axle components and one ring component were synthesized by the combination of a coupling reaction using a transition-metal catalyst and a metal-template approach. Thus, [2]rotaxanes were prepared by the oxidative dimerization of alkyne promoted by macrocyclic phenanthroline–CuI complexes. The [2]rotaxane was reacted with a CuI salt and an acyclic ligand to generate a tetrahedral
