Quest for the <b>Ncb</b>-type Metal–Organic Framework Platform: A Bifunctional Ligand Approach Meets Net Topology Needs

Abstract

A custom-designed bifunctional ligand was used to connect an in situ formed Co₃(OH) cluster affording a porous metal-organic framework, which represents the first case of ncb-type networks constructed from a single kind of ditopic ligand. Noticeably, the activated MOF shows high volumetric C₂H₂ uptake and excellent adsorption selectivity for C₂H₂/CO₂ separation at room temperature with a low sorption heat.
