Abstract

A pivotal guest role: A new porphyrin polymer, poly(PorZn⋅DD) (see picture, pink/purple), composed of a porphyrinatozinc and a porphyrin double‐decker complex as a repeating unit was synthesized. In poly(PorZn⋅DD), porphyrinatozinc complexes recognize a divalent amine (tan/red) to induce an intramolecular pivoting motion through the rotation of porphyrin double‐decker complexes and the polymer undergoes shortening and compaction.

Abstract

Abstract: A macrocyclic host molecule that comprised two different rotating modules, cerium(IV) bis(porphyrinate)s and ferrocenyl rotating units, exhibiting contraction/expansion motion was synthesized, which can be regarded as a prototype of artificial molecular spring driven by cooperative guest binding in 1:6 stoichiometry.
