Design and synthesis of two porous metal-organic frameworks with nbo and agw topologies showing high CO2 adsorption capacity.

Two novel porous copper-based metal-organic frameworks with nbo and agw topologies have been designed and synthesized using tetracarboxylate and tricarboxylate ligands, respectively. They possess large surface areas and high CO2 adsorption capacities (up to 170 cm(3)/g or 7.59 mmol/g at 0 °C under ambient pressure).
