Abstract: Metal-organic framework materials (MOFs) are highly porous entities comprising a multidentate organic ligand coordinated to multiple metal centers. MOFs having ambient condition stability may comprise a plurality of metal clusters comprising one or more M4O clusters (M is a metal), and a plurality of 4-pyrazolecarboxylate ligands coordinated to the plurality of metal clusters to define an at least partially crystalline network structure having a plurality of internal pores. The MOFs may have a Pa3 symmetry, which upon activation may convert into Fm3m symmetry. Methods for synthesizing the MOFs may comprise combining a metal source, such as a preformed metal cluster, with 4-pyrazolecarboxylic acid, and reacting the preformed metal cluster with the 4-pyrazolecarboxylic 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-pyrazolecarboxylate.

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. 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.

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.
