| Outline of Final Research Achievements |
We aimed to develop new open/close mechanisms of host structures that can be used to control the guest uptake/release rates. We introduced cobalt(III) ions into the newly designed tris(saloph) cage and bis(saloph) macrocyclic host molecules. The introduction of hexanediamine ligands at the cage apertures efficiently suppressed the guest uptake into the cage cavity. In the case of the macrocyclic system, the counteranions at the capping sites efficiently reduced the guest uptake and exchange rates. By taking advantage of the slow guest uptake behavior, we developed a new on-demand type guest exchange system, in which the guest exchange can be accelerated by counteranion.
