Ultra-micropores are typically made of small ligands and hence exhibit significant rigidity. This has made them find a special place in gas separation and storage. Stepping out of this realm, we have managed to introduce flexibility into these otherwise rigid frameworks via a 'by design' approach. Regulated flexibility introduced to these MOFs imparts 'Molecular Sieving' behavior. We have exploited this flexibility to gain CO2-specific adsorption from these otherwise non-porous MOFs. Here we will discuss the concept of "Hard-Soft Gate Control (HSGC)," a simple chemical tool to introduce porosity in MOFs. We will shed light on the intricacies of the concept when applied to MOFs. Our choice of achieving the MOF flexibility via the metal-ligand coordination makes the approach highly tunable, unique and versatile.
