Multicomponent Molecular Systems Incorporating Porphyrins and Copper(<scp>I</scp>) Complexes: Simultaneous Synthesis of [3]‐ and [5]Rotaxanes

Abstract

A copper(I)-templated synthesis furnishes rotaxanes, in which porphyrin subunits serve as bridges and bulky stoppers and the threaded rings contain chelating phenanthroline groups. A [5]rotaxane is shown schematically on the right, ○ = CuI, thick lines = phenanthroline units, ⋄ = porphyrins.
