title = "A preliminary step toward molecular spring driven by cooperative guest binding",
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.",
