Summary: The self-assembled behaviors between calixpyridinium and two pyrenesulfonate guests were studied, revealing differences in morphology, properties, and iodine capture capability. PS guests formed spherical aggregates, while PyTS guests formed rodlike aggregates. The calixpyridinium-PyTS aggregates showed strong green fluorescence and had the ability to adsorb iodine in both liquid and vapor phases, whereas the calixpyridinium-PS aggregates could not capture iodine. The diverse capabilities were determined by the self-assembled structure at the molecular level.

Summary: Synthetic chemists have developed various methods to synthesize molecules, polymers, and networks, but have long lacked the ability to prepare two-dimensional polymers from designed monomers. Recent advances in polymerization strategies and characterization methods have enabled the realization of covalently linked macromolecular sheets. Three predominant 2D polymerization strategies have emerged, producing 2DPs as either monolayers or multilayer assemblies.

Summary: ZIF-8 membranes prepared on polyamide substrates demonstrated successful separation of acetylene/methane and acetylene/carbon dioxide mixtures with separation factors of 12.1 and 1.8 respectively. The separation mechanism for C2H2/CH4 is attributed to acetylene affinity and molecular sieving, while C2H2/CO2 separation is related to thermodynamic factors. This study marks the first successful separation of C2H2 from CH4 and CO2 by MOF membranes.

Summary: The study demonstrates that a chiral metal-organic framework can guide the formation of highly chiral nanocomposites with intense chiral signals from buckminsterfullerene through in situ self-assembly strategy. Experimental and theoretical studies reveal that the chiral induction is attributed to the hybridization of molecular orbitals with the pore surface of the MOF.

Summary: This paper proposes a design approach using mixed metal-organic frameworks (MOFs) as tunable stationary phases in liquid chromatography (LC). By systematically designing ligands, the pore sizes in the MOFs can be tuned. Columns packed with the MOFs and their mixed-particle/solid-solution stationary phases are prepared and tested for the retention capability of polyethylene glycol (PEG) in LC. The results demonstrate that mixed-linker solid-solution MOFs have higher retention capability compared to pure MOF stationary phases, due to their specific nanostructures.

Summary: This report presents a bottom-up synthesis method for a polymer-based 2D electrolyte using a metal-organic framework (MOF) as a template. Crosslinking polymerization of methyl methacrylate (MMA) within MOF nanochannels resulted in poly(methyl methacrylate) (PMMA) monosheets. Hydrolysis of the precursor polymer gave poly(methacrylic acid) (PMAA) sheets. PMAA-1 exhibited high solubility and viscous liquid-like nature when dispersed in water at a pH higher than 5.7, and the addition of Al3+ ions promoted hydrogel formation.

Summary: Polyacrylonitrile (PAN) nanosheets with unimolecular thickness were successfully synthesized by cross-linking polymerization in the 2D nanospaces of a metal-organic framework. The ultrathin 2D network structure inhibited crystallization and allowed for efficient thermal transformation reaction of PAN. The amorphous nature of the PAN nanosheets facilitated thermal dehydroaromatization reactions to yield a ladder polymer structure with a highly extended conjugated system. Notably, further carbonization of this ladder polymer produced graphitic carbon with a highly ordered structure due to the well-defined precursor structure.

Summary: The self-adaptability of galvanostatic electrolysis was found to be helpful in a multistage chemo- and diastereoselective electrochemically promoted cyclodimerization of chalcones. Through a series of reductive events, densely functionalized cyclopentanes with five contiguous stereocenters were obtained (25 examples, yields up to 95%, dr values up to >20:1). Further experimental and electrochemical investigations indicated the crucial role of dynamic kinetic resolution of the aldol intermediate in the reaction mechanism.
