Summary: By utilizing solvent-oriented structural self-assembly and solvent-induced single-crystal to single-crystal transformation strategies, eight structurally distinct Cd-CPs were controllably synthesized with the same linkers for the first time. The significant role of solvents in the self-assembly and transformations in CPs has been demonstrated, and rare reversible CP-based phase transition phenomena at low temperatures were observed, including the first example of a novel turn-on-off CP-based Fe3+ ion sensor.

Summary: Microencapsulated phase change materials (MEPCMs) containing paraffin were prepared using SiO2 and Cu-BTC MOF as shell materials. The synthesized materials were characterized and evaluated for their benzene vapor sorption, NH3 adsorption, and formaldehyde adsorption capacities. The MEPCM exhibited a melting temperature of 22.7 degrees C, latent heat of 84.5 J/g, and encapsulation ratio of 44.5%. After 100 melting-freezing cycles, the heat storage and release capacities were minimally decreased. The MEPCM also showed potential for indoor building purification and improving the living environment.

Summary: Dyed wastewater has a serious impact on living organisms and must be treated before being released into the environment. Metal organic frameworks (MOFs) have been proposed as the most effective method for dye wastewater removal due to their high adsorption capacity and adjustable pore diameter and surface morphology. This study aims to evaluate the effectiveness of different types of MOFs in dye separation from wastewater and includes the examination of adsorption isotherms, kinetics, and characterization studies. The desorption and reuse of MOFs are also considered.

Summary: With the increasing population, industrialization, and agriculture, water contamination has adverse effects on both individuals and ecosystems. Metal-organic frameworks (MOFs) have large surface area and porosity, making them promising adsorbents for removing pollutants like heavy metals from contaminated water. This study focuses on examining copper (II) benzene-1,3,5-tricarboxylate (Cu-BTC) MOFs and understanding their mechanism for adsorbing lead (II) from aqueous solution.

Summary: In this study, Cu-BTC@Fe3O4 composite materials were prepared through a secondary growth strategy, and the effects of different activation solvents and temperatures on their adsorption performance were investigated. The results showed that ethanol as an activation solvent had higher adsorption capacity, while temperature change had little influence on pore structure.

Summary: This study investigates the effect of changes to the divalent metal node on the thermodynamic stability of zeolitic imidazolate frameworks. The use of nodes with larger ionic radius metals stabilizes the porous sodalite topology. Contrary to popular belief, the 2D frameworks are energetically stable, shedding light on the energetic landscape of these materials.

Summary: In this study, a series of lanthanum-based metal-organic frameworks were synthesized for fluoride removal in water, showing higher adsorption capacities compared to other adsorbents. The adsorption isotherms of La-MOFs for fluoride fit well with the Langmuir isotherm model. La-MOFs are suitable for fluoride removal in a relatively wide pH range.

Summary: Adsorptive separation is crucial in various industries, but the requirements for adsorbents differ during adsorption and desorption processes. To address this challenge, the development of process-oriented smart adsorbents (POSAs) that dynamically adjust pore structures and surface properties is essential for enhancing efficiency in adsorption and desorption simultaneously.

Summary: The study focused on synthesizing polyMOF ligands featuring MOF-forming benzenedicarboxylic acid linkers using common radical polymerization techniques: reversible addition fragmentation chain transfer (RAFT) polymerization and free radical polymerization (FRP). It was found that high-dispersity ligands prepared through FRP formed crystalline polyMOFs, while low-dispersity ligands prepared through RAFT required additional H(2)bdc to yield crystalline materials similar to MOF-5 and UiO-66. This work suggests that ligand dispersity is a key factor for polyMOF synthesis and presents new possibilities for developing polymer-MOF hybrids based on radical polymerization.

Summary: Metal-organic frameworks (MOFs) are efficient carriers for controlled drug delivery due to their large surface area and adjustable pore size. A new approach called Pore Space Partition (PSP) was used to effectively encapsulate and pH-controlled co-delivery of two guest molecules. ZIF-8's pore space was partitioned by encapsulating the large molecule ursolic acid (UA), and the remaining space was filled with the small molecule 5-fluorouracil (5-FU). This approach resulted in a high loading capacity of UA (12.80 wt %) and 5-FU (11.20 wt %) in the 5-FU&UA@ZIF-8. This smart carrier exhibited pH-controlled delivery of UA and surprisingly showed pH-responsive delivery of 5-FU after pore space partition. The co-delivery of 5-FU and UA demonstrated excellent anticancer performance against 4T1 cells.
