Long Time CO₂ Storage Under Ambient Conditions in Isolated Voids of a Porous Coordination Network Facilitated by the "Magic Door" Mechanism.

ABSTRACT: A coordination network containing isolated pores without interconnecting channels is prepared from a tetrahedral ligand and copper(I) iodide. Despite the lack of accessibility, CO₂ is selectively adsorbed into these pores at 298 K and then retained for more than one week while exposed to the atmosphere. The CO₂ adsorption energy and diffusion mechanism throughout the network are simulated using Matlantis, which helps to rationalize the experimental results. CO₂ enters the isolated voids through transient channels, termed "magic doors", which can momentarily appear within the structure. Once inside the voids, CO₂ remains locked in limiting its escape. This mechanism is facilitated by the flexibility of organic ligands and the pivot motion of clust
