An amine functionalized rht-type metal-organic framework with the improved performance for gas uptake

• Dendritic hexacarboxylate linker containing amine and triazole groups
• Amine functionalized rht-type copper(II) metal-organic framework
• High CO2 and H2 uptake capacities and selectivity of CO2 over N2

A dendritic hexacarboxylate ligand featuring amine and triazole groups was rationally designed and synthesized, which was employed to construct a (3,24)-connected rht-type copper(II) metal-organic framework (MOF, NTU-105-NH2) under solvothermal conditions. The desolvated amine-functionalized MOF demonstrated improved CO2 and H2 uptake capacity as well as significant higher selectivity towards CO2 over N2 in comparison to its parent MOF.

A triazole and amine dually functionalized MOF exhibited high CO2 and H2 uptake capacity as well as high selectivity towards CO2 over N2.Figure optionsDownload as PowerPoint slide
