“…Metal-organic interactions provide highly rigid bonding to produce hybrid framework structures using coordination bonding [28][29][30][31][32][33] or ionic bonding 34 . The representative materials are metal-organic frameworks (MOFs), which were invented by the pioneering work of the Yaghi group.…”

Considerable research approaches have focused on improving the crystallinity of conducting polymers to enhance the electrical conductivity. However, it is difficult to control the arrangement of polymer chains without the use of expensive and complex methods because of the intrinsic morphology of polymers. Herein, we report a one-step in situ process to produce controlled molecular-scale ordered polyaniline (PANI) films by coordination crosslinking with Zn ions using solvent-vapor thermal annealing (SVTA). The resulting PANI film crosslinked by Zn coordination has a face-centered cubic structure at the molecular scale, which was confirmed by high-voltage electron microscopy. The in situ coordination crosslinking produced a new class of molecular ordering in the PANI films and drastically enhanced their conductivity, showing their potential for use in various electronic and energy devices.

“…Establishing a greater understanding of such factors is expected to play an important role in the successful integration and optimisation of MOFs within higher-order structures. In one approach to overcoming the challenges of integration and loading of MOF particles into composite materials, Cohen and co-workers have developed polyMOFs, 94 hybrid materials in which the MOF 'additive' and the polymer 'support' are chemically integrated. Such systems were initially reported with MOF-5 analogues but have been extended to photo-linked UiO-66 composites 95 and used to produce high MOF-loading mixed matrix membrane composite materials.…”

Metal-organic Frameworks are a unique class of materials well known for their crystallinity and ultra-high porosity. Since their first report over fifteen years ago, research in this area has sought to actively exploit these properties, especially in gas adsorption. In this article we canvass some emerging topics in the field of MOF research that show promise for new applications in areas such as biotechnology, catalysis, and microelectronics. 26 and Cytochrome c 27 into Tb-based MOFs. These examples were limited to biomacromolecules with sizes smaller than the MOF cavities, although more recent work by Yaghi and coworkers 28has demonstrated the precise tuning of the pore size to adsorb and accommodate bigger biomacromolecules, such as myoglobin and green fluorescent protein.

“…CO2/N2 selectivities, however, reached a maximum at 23 wt % and then declined at 40 wt % signaling the presence of interfacial defects induced by the agglomeration of the MOF crystals at high loadings. A novel approach for the preparation of polymers that inherently incorporate controlled porosity came from the work of Z. Zhang, et al in 2015 with the synthesis of polyMOFs [255]. Since the first examples of the preparation of MOF-based MMMs, the aim was to disperse perfectly the crystallites in the polymer matrix without aggregation and voids at the interface.…”

Origins and Evolution of Inorganic-Based and MOF-Based Mixed-Matrix Membranes for Gas Separations

Abstract:Gas separation for industrial, energy, and environmental applications requires low energy consumption and small footprint technology to minimize operating and capital costs for the processing of large volumes of gases. Among the separation methods currently being used, like distillation, amine scrubbing, and pressure and temperature swing adsorption, membrane-based gas separation has the potential to meet these demands. The key component, the membrane, must then be engineered to allow for high gas flux, high selectivity, and chemical and mechanical stability at the operating conditions of feed composition, pressure, and temperature. Among the new type of membranes studied that show promising results are the inorganic-based and the metal-organic framework-based mixed-matrix membranes (MOF-MMMs). A MOF is a unique material that offers the possibility of tuning the porosity of a membrane by introducing diffusional channels and forming a compatible interface with the polymer. This review details the origins of these membranes and their evolution since the first inorganic/polymer and MOF/polymer MMMs were reported in the open literature. The most significant advancements made in terms of materials, properties, and testing conditions are described in a chronological fashion.
