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. Crystallization may be problematic in some instances when secondary binding sites are present in the multidentate organic ligand. Multidentate organic ligands comprising first and second binding sites bridged together with a third binding site comprising a diimine moiety may alleviate these issues, particularly when using a preformed metal cluster as a metal source to form a MOF. Such MOFs may comprise a plurality of metal centers, and a multidentate organic ligand coordinated 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. Particular MOFs may comprise N,N′-di(1H-pyrazol-4-yl)ethane-1,2-diimine as a multidentate organic ligand.

Abstract: A method suitable for use in investigating synthesis conditions for metal-organic frameworks may include: identifying synthesis conditions that includes a first solvent system by which a metal-organic framework is successfully synthesized; and synthesizing the metal-organic framework under substantially the same synthesis conditions but with a second solvent system (or a comparable solvent system) having a difference (Ra) between Hansen solubility parameters of 5 MPa0.5 or less as compared to the first solvent system.

Abstract: Provided herein are adsorption materials comprising a metal-organic framework comprising metal ions of metals, a plurality of organic linkers and one or more modulator where each modulator forms a localized defect. Each organic linker in the plurality of organic linkers creates a bridge between metal ions. Each modulator is connected to only one metal chain. The adsorption material further comprises one or more ligands. Each ligand in the plurality of ligands can be an amine or other Lewis base (electron donor) appended to a metal ion of the metal-organic framework.

Abstract: Provided herein are adsorption materials comprising a mixed-metal mixed-organic framework comprising metal ions of two or more distinct metals and a plurality of organic linkers. Each organic linker in the plurality of organic linkers is connected to a metal ion. The adsorption material further comprises a plurality of ligands. In an aspect, each respective ligand in the plurality of ligands is an amine or other Lewis base (electron donor) appended to a metal ion in the two of more distinct elements of the mixed-metal organic framework to provide a mixed-metal mixed-organic framework system.

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.
