AbstractProton‐conducting metal–organic frameworks (MOFs) have attracted attention as potential electrolytes for fuel cells. However, research progress in utilizing MOFs as electrolytes for fuel cells has been limited, mainly due to challenges associated with issues such as the fabrication of MOF membranes, and hydrogen crossover through the MOF's pores. Here, we report proton conductivity and fuel cell performance of a self‐standing membrane prepared from of a bismuth subgallate MOF nanosheets with non‐porous structure are reported. The fabricated MOF nanosheet membrane with no binding agent exhibitsed structural anisotropy. The proton conductivity in the membrane thickness direction (4.4 × 10−3 S cm−1) at 90 °C and RH 100% is observed to be higher than that in the in‐plane direction of the membrane (3.3 × 10−5 S cm−1). The open circuit voltage (OCV) of a fuel cell with ≈120 µm proton conducting membrane is 1.0 V. The non‐porous nature of the MOF nanosheets contributes to the relatively high OCV. A fuel cell using ≈40 µm membrane as proton conducting electrolyte records a maximum of 25 mW cm−2 power density and a maximum of 109 mA cm−2 current density with 0.91 V OCV at 80 °C in humid conditions.

AbstractThickness of two‐dimensional (2D) metal‐organic frameworks (MOFs) govern their intriguing functionalities. Primarily this thickness is controlled by the stacking between the metal‐organic layers (MOL). It is observed that until now such modulating factors for stacking efficiency of MOL are not well studied. Here, we report a fundamental hypothesis to comprehend regulation of stacking efficiency among MOLs as a function of chemical structure of organic ligands (dicarboxylic acids and pillar linkers). This basically involves a series of isostructural three‐dimensional (3D) MOFs which contain linkers of variable chemical nature that could be depillared to generate 2D stacked MOFs of different thickness. Depending on the linkers, we encountered the formation of single MOL to stacked multiple MOLs as evidenced from atomic force microscopic and other experimental analysis. The present study gives a concrete correlation between the stacking within 2D MOFs (from monolayer to multilayers), and their 3D counter parts, which may provide a thickness tuning pathway for 2D MOFs.

A novel three-dimensional two-fold interpenetrated bi-porous metal-organic framework IPM-325 (IPM: IISER Pune Materials) having pcu topology was synthesized at room temperature. Single crystal X-ray diffraction (SC-XRD) study revealed that the compound crystallizes in monoclinic lattice with molecular formula {[Zn(L)2 (SiF6)] (CH2Cl2) xG}n where G = Guests). All metal centers were found to have octahedral geometry. From single crystal analysis it can be inferred that SiF62− anion play a vital role in extending the dimensionality of the framework by bridging between two metal centers. Interestingly, IPM-325 exhibited two-step structural transformation maintaining the crystallinity of the framework as characterized by powder X-ray diffraction (PXRD).

Utilization of the robust metal-carbonate backbone in a series of water-stable, anionic frameworks has been harnessed for the function of highly efficient solid-state ion-conduction. The compact organization of hydrophilic guest ions facilitates water-assisted ion-conduction in all the compounds. The dense packing of the compounds imparts high ion-conducting ability and minimizes the possibility of fuel crossover, making this approach promising for design and development of compounds as potential components of energy devices. This work presents the first report of evaluating ion-conduction in a purely metal-carbonate framework, which exhibits high ion-conductivity on the order of 10-2 S cm-1 along with very low activation energy, which is comparable to highly conducting well-known crystalline coordination polymers or commercialized organic polymers like Nafion.

A luminescent coordination polymer was synthesized based on a linker prefunctionalization-based design principle coupled with an appropriate template selection protocol adopted during crystallization. Luminescent linker derived photoluminescence emission signature together with the reversibly dynamic host polymer exhibited a unique response toward environmentally toxic aromatics in the solid state, arguably crucial for the designed development of toxin-responsive solid materials.

AbstractDerived from a strategically chosen hexafluorinated dicarboxylate linker aimed at the designed synthesis of a superhydrophobic metal–organic framework (MOF), the fluorine‐rich nanospace of a water‐stable MOF (UHMOF‐100) exhibits excellent water‐repellent features. It registered the highest water contact angle (≈176°) in the MOF domain, marking the first example of an ultrahydrophobic MOF. Various experimental and theoretical studies reinforce its distinctive water‐repellent characteristics, and the conjugation of superoleophilicity and unparalleled hydrophobicity of a MOF material has been coherently exploited to achieve real‐time oil/water separation in recyclable membrane form, with significant absorption capacity performance. This is also the first report of an oil/water separating fluorinated ultrahydrophobic MOF‐based membrane material, with potential promise for tackling marine oil spillages.

AbstractA three‐dimensional water‐stable cationic metal–organic framework (MOF) pillared by a neutral ligand and with NiII metal nodes has been synthesized employing a rational design approach. Owing to the ordered arrangement of the uncoordinated tetrahedral sulfate (SO42−) ions in the channels, the compound has been employed for aqueous‐phase ion‐exchange applications. The compound exhibits rapid and colorimetric aqueous‐phase capture of environmentally toxic oxoanions (with similar geometries) in a selective manner. This system is the first example of a MOF‐based system which absorbs both dichromate (Cr2O72−) and permanganate (MnO4−) ions, with the latter acting as a model for the radioactive contaminant pertechnetate (TcO4−).

Highly selective and sensitive aqueous phase-detection of the well-known nitro explosive environmental pollutant 2,4,6-trinitrophenol (TNP) by a water-stable, porous luminescent metal–organic framework has been reported. The presence of a guest accessible aliphatic amine functionality in the MOF channels has been strategically harnessed for serving the purpose of exclusive TNP-sensing in water even in concurrent presence of other nitro aromatic and nitro aliphatic analytes.

A new function of metal-sulfate-based coordination polymer (CP) for proton conduction was investigated through rational integration of a continuous water array and protonated amine in the coordination space of the CP. The H-bonded arrays of water molecules along with nitrogen-rich aromatic cation (protonated melamine) facilitate proton conduction in the compound under humid conditions. Although several reports of metal-oxalate/phosphate-based CPs showing proton conduction are known, this is the first designed synthesis of a metal-sulfate-based CP bearing water arrays functioning as a solid-state proton conductor.

The separation of styrene and ethylbenzene mixtures is industrially important and is currently performed in highly energy-intensive vacuum distillation columns. The primary objective of our investigation is to offer an energy-efficient alternative for selective adsorption of styrene by a flexible metal-organic framework, DynaMOF-100. The structural transformation of DynaMOF-100 is specifically triggered on inclusion of styrene within the framework; this structural transformation is reversible. The styrene/ethylbenzene adsorption selectivity, originated as an outcome of the framework flexibility, is found to be much superior to the only two MOFs yet reported, serving styrene/ethylbenzene separation purpose.

Owing to the conformational (cis or trans) flexibility of a N-donor ligand, the combinations of the same and Cd(ClO4)2 under variable solvent templates afforded two supramolecular isomers based on two-dimensional metal-organic frameworks. Both compounds contain weakly coordinating ClO4(-) anions attached to the metal centers. Both frameworks showed facile anion exchange behaviors with various kinds of foreign anions. Moreover, both frameworks showed anion-driven structural dynamism and exhibited the preferential uptake of strongly coordinating anions over others. Anion-regulated modulation in luminescent behaviors was also observed in both cases.
