A versatile metal-organic framework for carbon dioxide capture and cooperative catalysis

A multi-functional MOF PCN-124 was constructed from Cu paddlewheel motifs and a judiciously designed novel ligand bearing carboxylate, pyridine, and amide groups. PCN-124 exhibits selective adsorption of CO2 over CH4 and excellent catalytic activity in a tandem one-pot deacetalization-Knoevenagel condensation reaction as a cooperative catalyst.
