Spherical 24 Butyrate Aggregate with a Hydrophobic Cavity in a Capsule with Flexible Pores: Confinement Effects and Uptake-Release Equilibria at Elevated Temperatures

Forced interaction: The encapsulation of a large assembly of organic species—the 24 butyrate unit, which exhibits a remarkable central spherical hydrophobic cavity spanned by 72 H atoms—in a porous capsule (see picture) leads to interesting interactions between the butyrates under the confined condi...

Summary:Forced interaction: The encapsulation of a large assembly of organic species—the 24 butyrate unit, which exhibits a remarkable central spherical hydrophobic cavity spanned by 72 H atoms—in a porous capsule (see picture) leads to interesting interactions between the butyrates under the confined conditions. The quarantine for the guests is lifted upon temperature increase: guests can easily leave and return.
