Porous Cobalt(II)–Organic Frameworks with Corrugated Walls: Structurally Robust Gas‐Sorption Materials

Resilient hosts: The porous coordination solids CUK-1 (see structure; Co purple, C gray, N blue, O red/pink) and CUK-2 are synthesized from unsymmetrical ligands and CoII ions. Even after the removal of co-crystallized guests, the host frameworks are exceptionally stable. CUK-1 shows a high capacity for H2 adsorption and is one of very few materials capable of separating N2 from O2.
