Aperture‐Controlled Cs <sup>+</sup> Uptake/Release Kinetics and Extremely Short Cs <sup>+</sup> –π Contact in Open‐Cage Cobalt(III) Metallocryptands
-π distances in the range of 2.98-3.04 Å, significantly shorter than the previously reported range of 3.3-3.6 Å, due to geometrical constraints imposed by the rigid metallocryptand framework with a 6.0 Å π-π spacing. Structural comparisons demonstrated that the steric bulk of the amine ligands modulates the cage aperture sizes, accounting for the observed kinetic trends.
