Abstract
Metal-organic framework materials (MOFs) are highly porous entities comprising a multidentate organic ligand coordinated to multiple metal centers, typically as a coordination polymer. MOFs may comprise a plurality of metal centers, and a multidentate organic ligand coordinated via at least two binding sites to the plurality of metal centers to define an at least partially crystalline network structure having a plurality of internal pores, and in which the multidentate organic ligand comprises first and second binding sites bridged together with a third binding site comprising a diimine moiety. The multidentate organic ligand may comprise a reaction product of a vicinal dicarbonyl compound and an amine-substituted salicylic acid to define the first, second and third binding sites. Particular MOFs may comprise 5,59'-(((1E,2E)-ethane-1,2-diylidene)bis-(azaneylylidene))bis(2-hydroxybenzoic acid) as a multidentate organic ligand.
