Ultrastable 3D cage-like metal–organic frameworks constructed using polydentate cyanurate ligands and their gas adsorption properties

An ultrastable cage-like MOFs (SrCu(HC 3 N 3 O 3 ) 2 ) was constructed by polydentate cyanurate ligand, which possesses the highest porosity up to 36.7% among cyanuric acid-based MOFs, and can achieve efficient C 3 H 4 /C 3 H 6 separation under dynamic conditions.
