Abstract: Fiber compositions are provided that incorporate metal organic framework (MOF) materials into the polymeric matrix of the fiber. The metal organic framework materials can be incorporated by including MOF particles into a “dope” or synthesis solution used to form the fiber. The dope solution can then be used to form fibers that include 5.0 wt % or more of MOF in the resulting polymeric structural material of the fiber, relative to a weight of the fibers. In some aspects, the metal organic framework material can correspond to a MOF with selectivity for adsorption of CO2.

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.

Abstract: Metal-organic frameworks are synthesized from either a high concentration synthesis where reaction solutions comprising increased reagent concentrations, or suspensions of reagents which exceed their solubility limit in the reaction solution in a high solids synthesis. In both approaches, the solubility of reagent is maximized by inclusion of a buffer, fixing a nominal pH of the reaction solution to allow metal-organic framework formation. These methods improve yields and scale up of metal-organic frameworks.

Abstract: Methods of making metal-organic frameworks in yields of at least about 50 percent by volume of metal-organic frameworks in a metal-organic framework material per liter of synthesis solution and/or about 75 molar percent of metal-organic frameworks in a metal-organic framework material are provided. Methods of making MOF Cu(Qc)2 in aqueous solutions are further provided where a solvent composition of less than about 30% volume water is combined with a buffer and a plurality of reagents to provide the synthesis solution.

Abstract: Provided herein are methods of novel methods of synthesizing a metal-organic framework system by vapor-phase appending of a plurality of ligands appended to a metal-organic framework. Also, provided are methods of recycling metal-organic framework systems by detaching the ligand and re-appending the same ligand or appending a different ligand to the metal-organic framework to provide a recycled or repurposed metal-organic framework system.

Abstract: Ink compositions are provided for using solvent-based additive manufacturing (SBAM) techniques to form contactor structures and/or structures for use in an adsorption or absorption contactor. Methods forming a contactor using SBAM are also provided. The ink compositions can include a substantial content of adsorbent particles to provide enhanced adsorption by a contactor. Metal organic framework (MOF) structures and zeotype framework structures are examples of types of adsorbent particles that can be incorporated into an ink composition for forming a contactor structure by SBAM. The ink can further include a polymeric component that can serve as the structural component of a polymeric structural material produced by the additive manufacturing method. Such a structural material can correspond to a polymeric material with incorporated adsorbent particles. In some aspects, the polymeric structural material and/or the adsorbent particles can have selectivity for adsorption of CO2 from a process fluid flow.

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: Methods are provided for appending amines to metal organic framework (MOF) compositions. In some aspects, the methods can allow for appending of amines in the solution or synthesis solution used for synthesizing a MOF. In such aspects, an amine-appended MOF can be formed without having to first separate and dry the underlying non-amine-appended MOF composition. In other aspects, amines can be appended to an existing MOF composition by exposing the MOF to a suitable amine in a protic solvent, such as water or an alcohol.
