A porous cobalt-based MOF with high CO 2 selectivity and uptake capacity

A porous cobalt-based metal–organic framework [CoL 2− ] n has been designed by self-assembling [Co 2 (COO) 4 ] paddlewheel SBUs and a novel trigonal hetero–functional ligand. [CoL 2− ] n exhibits large CO 2 uptake and selectivity.
