Summary: Carboxyl-containing and amine-rich Zn-MOF was synthesized using a simple stirring method, with the addition of organic amines reducing synthesis time to 2 hours. The hierarchical pores in the obtained Zn-MOF facilitated substrate diffusion and interaction with CO2, resulting in efficient catalysis of CO2 fixation with epoxides. The catalyst showed improved activity compared to traditional Zn-MOF, with a 97% yield of propene carbonate achieved at room temperature.

Summary: Poly(ionic liquid)s (PILs) have gained attention due to their excellent properties similar to ionic liquids and polymers. However, their applications are limited due to blockage of active sites by abundant and flexible ions. This study reports the synthesis of a PIL/graphene composite catalyst (iPOP-ZnTPy@GNFs) with controlled particle size and dispersion state. The iPOP-ZnTPy@GNFs exhibited higher catalytic activity in the CO2 cycloaddition reaction and efficiently converted epoxides to cyclic carbonates at room temperature or atmospheric pressure. The catalyst also showed excellent substrate scope, catalytic diversity, and reusability.

Summary: This study synthesized and described two new metal-organic frameworks (MOFs) and investigated their structures and properties. The results showed that both MOFs exhibited multifunctionality, being able to recognize organic amines and fix CO2 into cyclic carbonates. Additionally, they displayed good fluorescence stability in aqueous media and high quenching efficiency for certain amine compounds. The mechanism of amine recognition was proposed to involve hydrogen bonding and pi-pi stacking interactions. Furthermore, both MOFs showed high catalytic efficiency in the cycloaddition reaction and were recyclable for multiple cycles without significant loss of their sensing or catalytic efficiency.

Summary: We report the synthesis and characterization of three novel lithium complexes (2b-d) with different hydrazonyl anthraquinonic backbones, tested in the ring-opening polymerization (ROP) of lactide and epsilon-caprolactone for synthesizing cyclic polymers. Various analytical methods, including NMR, MS spectrometry, and FTIR spectroscopy, are used to identify the catalyst structures. The resulting cyclic polymers are characterized using MALDI-TOF, end-group NMR analysis, and PGSE diffusion NMR. Differences in selectivity (linear vs cyclic) are observed when using ligand backbones with different abilities and/or steric restrictions.

Summary: According to the World Health Organization, there are over 422 million people worldwide suffering from diabetes. The commonly used oral treatment for type 2 diabetes is metformin (MTF), which is formulated as a hydrochloride to increase solubility. However, MTF is highly hygroscopic and unstable. On the other hand, non-steroidal anti-inflammatory drugs (NSAIDs) have low solubility and require high doses, leading to potential side effects. This study aims to synthesize novel drug-drug pharmaceutical solids combining MTF and NSAIDs to improve their physicochemical properties, and the results show promising potential for the development of these multicomponent solid formulations.

Summary: Mesoporous silica-supported Zr-MOF-808 catalysts were synthesized and tested for the aldol condensation of furfural and methyl isobutyl ketone to bio-jet fuel precursors. The addition of Zr-MOF-808 nano-crystals to silica scaffolds resulted in well-dispersed Zr species with strong Lewis acidity. The Zr-MOF-808/silica hybrid materials exhibited higher condensation activity compared to unsupported Zr-MOF-808, and the textural properties of the silica support played a significant role in the catalytic performance.

Summary: Drug-drug salts are a new type of pharmaceutical multicomponent solid that contains active pharmaceutical ingredients (APIs) in ionized forms. They have garnered interest in the pharmaceutical industry for their ability to coexist and improve the pharmacokinetics of the APIs, particularly those with dose-dependent secondary effects like NSAIDs. In this study, six multidrug salts consisting of different NSAIDs and the antibiotic ciprofloxacin were synthesized and characterized. Solubility, stability, and bacterial inhibition assays were performed, showing enhanced solubility of NSAIDs without affecting antibiotic efficacy.

Summary: Pharmaceutical multicomponent solids effectively modulate the physicochemical properties of active pharmaceutical ingredients. Polyphenols, with their wide safety profile and antioxidant properties, are interesting coformers for designing pharmaceutical cocrystals. Mechanochemical synthesis was used to obtain novel 6-propyl-2-thiouracil multicomponent solids, which were fully characterized using X-ray diffraction methods. Computational methods were also employed to analyze the supramolecular organization, revealing a robust structure influenced by the different positions of the hydroxyl groups in the polyphenolic coformers. These cocrystals show enhanced solubility but limited thermodynamic stability in aqueous media, lasting only 24 hours.
