Summary: Zeolitic imidazolate frameworks (ZIFs) have been developed to mimic the structural characteristics of zeolites, with high surface area and adjustable pore size being their main features. The emerging hybrid zeolitic imidazolate frameworks (HZIFs) combine the advantages of zeolites and ZIFs, such as high stability and porosity. HZIFs find wide applications in electrocatalysis, photocatalysis, and ion storage, contributing to the progress in material chemistry, coordination chemistry, and structural chemistry.

Summary: By coating a uniform layer of BMZIF onto the surface of MoO3 nanorods, a core-shell catalyst Mo2C@BMZIF-700 degrees C (4 h) was created, enabling the high selective conversion of guaiacol to phenol under relatively mild reaction conditions. The catalyst also exhibited selective cleavage of the methoxy group of lignin derivatives, making it suitable for biomass catalysis. It showed excellent recyclability and stability without changing its structure or active species.

Summary: Nanoscaled metal organic frameworks, such as zeolitic imidazolate frameworks (ZIFs), have shown great promise in the biomedical field as a novel type of organic-inorganic hybrid coordination polymeric nanomaterials. ZIFs, constructing with metal ions and imidazolate linkers, possess unique advantages of high porosity, large surface area, good biocompatibility, pH sensitivity, making them attractive platforms for delivering drugs, imaging probes, and biomacromolecules for cancer diagnosis and therapy. This review focuses on the latest research in biosensing, cancer imaging, and phototheranostics using ZIFs within the past 5 years, discussing synthesis strategies, characterization, and functionalization, as well as the potential future opportunities and challenges in translational medicine.

Summary: Researchers developed a novel nanostructure, ZIF-8-Cu1,Nix(OH)2@Cu, by combining sol-gel and co-precipitation methods. The synthesized nanocomposite was characterized, and then coated onto a PEDOT:PSS/ITO electrode for antibody immobilization. The resulting ZIF-8-Cu1,Nix(OH)2@Cu/PEDOT:PSS/ITO electrode was used for the detection of cystatin C, a biomarker for chronic kidney disease. The proposed sensor exhibited excellent electrochemical sensing performance with a low detection limit, high selectivity, stability, and reproducibility compared to a bare ZIF-8/PEDOT:PSS/ITO-based immunosensor. The clinical feasibility of the sensor was confirmed by measuring human serum samples.

Summary: ZIF-8-PhIm was prepared for the removal of p-nitrophenol from petrochemical wastewater. It exhibited stronger interactions, a multistage pore structure, increased hydrophilicity, and higher adsorption capacity compared to ZIF-8 materials. The adsorption process was described by the Langmuir isotherm and pseudo-second-order kinetic models, and hydrogen bonding and p-p interactions played a dominant role.

Summary: First-principles crystal structure prediction (CSP) is a powerful method for discovering new materials by predicting and evaluating their properties based on the underlying components. In this study, metal-organic frameworks (MOFs) were discovered using CSP, providing an alternative to conventional techniques relying on geometry and experimental screening. Experimental validation of the CSP procedure was done by synthesizing materials with structures matching the lowest-energy calculated structures, and properties such as combustion energies were evaluated from the CSP-derived structures.
