Abstract

See full text

Metal-organic framework materials (MOFs) are highly porous entities comprising a multidentate organic ligand coordinated to multiple metal centers, typically as a coordination polymer. Some highly porous MOFs lack stability at ambient conditions. MOFs having ambient condition stability may comprise a plurality of metal clusters (M4O clusters, M=a metal), and a plurality of 4-(1H-pyrazol-4-yl)benzoate ligands coordinated to the plurality of metal clusters to define an at least partially crystalline network structure having a plurality of internal pores. Methods for synthesizing these MOFs may comprise combining a metal source, such as a preformed metal cluster, with 4-(1H-pyrazol-4-yl)benzoic acid, and reacting the preformed metal cluster with the 4-(1H-pyrazol-4-yl)benzoic acid to form a MOF having an at least partially crystalline network structure with a plurality of internal pores defined therein and comprising a plurality of metal clusters coordinated to a multidentate organic ligand comprising 4-(1H-pyrazol-4-yl)benzoate.
