Abstract

original image

Open and friendly: The smallest member of the rht-type metal–organic frameworks (MOFs, see picture) constructed by a hexacarboxylate ligand with a nitrogen-rich imino triazine backbone shows a significantly enhanced gas binding affinity relative to all other isoreticular rht-type MOFs. The high adsorption capacity and remarkable selectivity of CO2 are attributed to the high density of open metal and Lewis basic sites in the framework.
