Summary: Two quaternary pyridinium-type cationic-based porous organic frameworks (DB-POF and LB-POF) were synthesized and incorporated into a PEO/LiTFSI matrix to prepare solid polymer electrolytes (SPEs). These POFs have higher polarizability, stable structure, and simple preparation, making them ideal for achieving rapid Li+ conductivity in SPEs. The inclusion of POFs in PEO-based SPEs positively impacts ion transport capacity, mechanical properties, and stability of the lithium metal anode.

Summary: The study investigates the binding of anions to the surface of an octanuclear coordination cage H-W in aqueous solution. Anionic aromatic fluorophores bind strongly to the cage, with up to six fluorescent anions binding to each face of the cubic cage. The study also introduces a fluorescence displacement assay to study the binding of other anions, with relative binding affinities of simple anions rationalized based on ease of desolvation, electrostatic factors, and the hydrophobic surface of the cage.

Summary: This study presented a precise surface modification method for water treatment membranes by grafting polymers to control the density of the modifying polymer, achieving precise control over fouling behavior of the membrane. By varying solvent types during immobilization reaction, high-density surface modification with poor solvents and low-density surface modification with good solvents were achieved, demonstrating that a membrane modified with higher molecular-weight polyMPC with a higher density was more effective for antifouling.

Summary: In this study, iron-based crystalline porous materials were constructed as drug delivery systems with high loading capacity and controllable structures. These materials exhibited high adsorption selectivity for anticancer drug 5-fluorouracil (5-Fu) due to their suitable pore size and electrostatic force. Furthermore, they demonstrated sustained release kinetics for up to 96 hours with pH-responsive controlled release, prolonging the release process and decreasing plasma concentration. The biocompatibility of the materials was also satisfactory. This work has significant research significance and application value for the development of novel drug delivery materials.

Summary: A novel geminized cationic amphiphilic polymer,PAGB(n), was synthesized and utilized to desorb asphaltenes by exposing preadsorbed asphaltene layers to PAGB(n) aqueous solution with different concentrations. The desorption process was studied using quartz crystal microbalance with dissipation (QCM-D), atomic force microscopy (AFM) and contact angle (CA) measurements. The desorbed mass of asphaltenes increased from approximately 31.6 ng/cm² to 799.5 ng/cm² as the concentration of PAGB(n) increased from 0.5 times the critical aggregation concentration (CAC) to 10.0 times the CAC, with significant improvement observed at 5.0 times the CAC. A gradual peeling off process of asphaltenes displaced by PAGB(n) aggregates from the solid/liquid interface was speculated based on the desorbed mass, AFM images, and surface wettability. The self-aggregation behavior of PAGB(n) on the solid-liquid interface was further investigated using dynamic light scattering (DLS) and transmission electron microscopy (TEM). A network aggregate consisting of spherical multisize micelles was formed, and a removal mechanism of asphaltenes from solid surfaces was proposed, providing insight into heavy oil recovery improvement.

Summary: This work demonstrates that water can depolymerize polyhedra with labile metal-ligand bonds in a cobalt-based coordination network, resulting in nonstoichiometric glasses. The addition of water molecules promotes the breakage of network bonds and coordination number changes, thereby lowering melting and glass transition temperatures. These structural changes alter the physical and chemical properties of the glass, similar to the concept of modifiers in oxides. This approach can be extended to other transition metal-based coordination networks, enabling diversification of hybrid glass chemistry.

Summary: In this study, a calixpyrrole-based chiral macrocyclic system, calix[1]furan[1]pyrrole[1]thiophene (1), was synthesized from an oligoketone. The macrocycle adopts a partial cone conformation and undergoes racemization via ring inversion. N-methylation of the pyrrole moiety suppresses racemization and enables chiral resolution. Furthermore, this system can also serve as a precursor to yield various calix[n]furan[n]pyrrole[n]thiophene products (n = 2-4), including the largest calix[n]pyrrole-like species to be structurally characterized.

Summary: In this paper, a selective DMF sensor using a molybdenum disulfide (MoS2) field-effect transistor (FET) is proposed. The sensor responds to DMF molecules but not to similar molecules of formamide, N,N-diethylformamide, and N,N-dimethylacetamide. The thin structure of MoS2-FET can be incorporated into a microfluidic chamber, which allows for real-time DMF monitoring by exchanging solutions subsequently. The designed device shows DMF monitoring in NaCl ionic solutions from 1 to 200 μL/mL. This work proposes the concept of selectively monitoring redox-inactive molecules based on the nonideal atomic affinity site on the surface of two-dimensional semiconductors.

Summary: In this study, a environmentally friendly method for synthesizing crystalline COFs from CO2 molecules as a precursor was proposed. The COFs showed high stability and a large surface area, and remained stable under strong acid, base, and high temperature conditions.

Summary: This study reports the achievement of spin-polarized radicals with extremely long spin-lattice relaxation times at room temperature in a metal-organic framework. The generation of persistent radicals through charge separation after photoexcitation and the successful transfer of spin polarization to these radicals have been demonstrated. This achievement in MOFs with nanopores accessible to guest molecules will play a significant role in highly sensitive quantum sensing and efficient dynamic nuclear polarization.
