Summary: By using various experimental techniques, it is shown that the nucleation of UiO-66 occurs through the solution-mediated hydrolysis of zirconium chloroterephthalates, which is autocatalytic. The nuclei of UiO-66 possess the same local environment as the crystals, but lack long-range order, which is gained during the crystallization. Crystal growth is the rate-determining step, while fast nucleation controls the formation of small crystals of UiO-66 with a narrow size distribution of about 200 nanometers.

Summary: Fabricating MOFs with missing linker defects is a common method to enhance catalytic performances, but the stability of the defects should be investigated first. In this study, it was found that 3-phenylpropionaldehyde (3-PPA) could coordinate with the missing linker defects of UiO-66, indicating the instability of the defects. 3-PPA acted as a molecular patch to modify the Rh/UiO-66 catalyst, repairing the open Zr-6 sites and significantly improving aldehyde selectivity (from 50.0% to 89.6%) in 1-hexene hydroformylation.

Summary: The acid-base properties of supports have a significant impact on the selectivity and activity of supported catalysts. In this study, a series of Pd-X-UiO-66 (X = -NO2, -NH2, and -CH3) catalysts with different acidity/alkalinity functional groups and encapsulated Pd(II) species were developed and their activities in dimethyl carbonate (DMC) catalysis were investigated. The Pd-NO2-UiO-66 catalyst with acidity functionalization exhibited the best catalytic behavior, with a DMC selectivity of 68% and a CO conversion of 73.4%. The results showed that the -NO2 group not only affected the interaction between X-UiO-66 and Pd(II) active sites, but also played a crucial role in the adsorption and activation of MN and CO, promoting the formation of the COOCH3* intermediate and DMC product.

Summary: A series of bimetallic UiO-66-NH2(Zr-Hf) metal-organic frameworks (MOFs) were prepared using a green hydrothermal method and tested for their photocatalytic and piezo-catalytic properties. Among them, UN(0.75Zr) showed the highest piezo-photocatalytic activity. The degradation rate for 40 mg L-1 rhodamine B (Rh B) reached 96.78% within 30 minutes, which was about 4.66 and 3.30 times higher than that of photocatalysis and piezo-catalysis, respectively. The study also identified the main reactive oxidizing substances and analyzed the intermediates generated during Rh B degradation, providing insights into a reasonable degradation pathway.

Summary: In the study, the selective adsorption properties of metal-organic frameworks UiO-66, sulfo-functionalized UiO-66, and amino-functionalized UiO-66 were investigated for efficient wastewater treatment. Different organic dyes were used as model pollutants, and UiO-66 showed high adsorption capacity for certain dyes based on their molecular size. The functionalization of UiO-66 enhanced its adsorption capacity for specific dyes. The ion-selective adsorption properties of UiO-66 were also demonstrated. Overall, functionalized UiO-66 shows promise as an adsorbent for removing organic pollutants from aqueous solutions.

Summary: New functional materials, including mixed matrix membranes and MOF monoliths, demonstrate superior performance in gas separation and storage applications compared to traditional materials. However, simulation techniques currently available are unable to fully capture the spatial complexity exhibited by most engineered materials. This study introduces the MicMec implementation of a micromechanical model as a systematic coarse-graining approach to access larger length scales and characterize the mechanical properties of these materials. The results show that the micromechanical simulations can achieve time steps 2 to 3 orders of magnitude larger than atomistic simulations, while accurately capturing the macroscopic mechanical properties of the spatially disordered material. MicMec implementation can serve as a complementary tool to existing atomistic and coarse-grained software, facilitating the computational design of new materials for pressing applications.

Summary: In this article, a novel strategy for preparing bistable porous nanocrystals is presented, which involves anchoring switchable molecules in the pores of a host matrix through strong host-guest interactions. The loaded nanocrystals, based on a prototypical Fe(III) spin-crossover complex in MOF-808, exhibit a hysteretic thermal spin transition close to room temperature, regardless of the complex loading and the MOF particle size, while maintaining high porosity, making them promising for applications in chemical sensing.

Summary: Cancer is a leading cause of death worldwide, with nearly 10 million deaths in 2020. Palladium complexes have great potential as anticancer agents, offering advantages over platinum drugs such as better speciation control and lower toxicity. This study developed two novel complexes and thoroughly investigated their speciation in solution, demonstrating their stability and behavior towards nucleic acid models and serum proteins. Furthermore, these complexes showed higher efficiency and specificity compared to the benchmark cisplatin drug due to their lower toxicity to healthy cells.

Summary: The microporous bioderived Al dicarboxylate MIL-160(Al) MOF in its shaped form has shown potential as a candidate for biogas upgrading (BU) and/or carbon capture and storage (CCS). The adsorption isotherms of CO2, CH4, and N2 at different temperatures and pressures were studied, revealing the loading capacities and fitting with the dual-site Langmuir model. Uptake rate experiments and Response Surface Methodology (RSM) were used to calculate the driving force coefficients and maximize selectivity for CO2/CH4 and CO2/N2 mixtures. Breakthrough curve experiments were simulated using ASPEN Adsorption, confirming the potential of MIL-160(Al) for BU and/or CCS applications.

Summary: Metal-organic frameworks (MOFs) have gained interest in biomedical applications, with the mesoporous iron(III) carboxylate MIL-100(Fe) being one of the most studied MOF nanocarriers. Nanosized MIL-100(Fe) particles coordinate with drugs to achieve high drug loading and controlled release. A study investigated the interactions between the anticancer drug prednisolone and nanoMOFs, showing that prednisolone with phosphate groups had the strongest interactions and slowed down degradation, while prednisolone with sulfate groups had lower efficiencies and easily released in phosphate media. The nanoMOFs maintained their structure even after drug loading and degradation. Scanning electron microscopy and X-Ray energy-dispersive spectrometry were used to analyze the structural evolution.

Summary: The synthesis of ZSM-5 zeolites with dendritic nanoarchitectures was achieved by functionalization of protozeolitic nanounits using amphiphilic organosilanes with different chain lengths. The presence of dendritic nanostructure positively influenced the textural and catalytic properties of ZSM-5 zeolite, with higher mesoporosity observed in the C14 and C18 samples. These materials also exhibited the highest catalytic activity in the aldol condensation reaction. The formation of a covalently stabilized mesophase during gel preparation was found to be essential for obtaining dendritic ZSM-5 zeolites.

Summary: Recent breakthrough experiments have identified iso-reticular Zr-MOFs, MIL-140B and MIL-140C, as promising sorbents for C6 isomer separation. The elution order of hexane isomers in MIL-140C exhibited an uncommon shift compared to MIL-140B, which was speculated to be caused by the flexibility of the MOFs. Through simulations, it was predicted that MIL-140B preferentially adsorbs n-C6 over 3MP, while MIL-140C slightly favors n-C6. The mobility of the isomers in MIL-140B and MIL-140C was found to be different, which explains the experimental inversion of elution order in MIL-140C.
