Summary: Conducting reactions in the solid state without solvents allows for structural characterization through single-crystal X-ray crystallography. Single-crystal to single-crystal reactions are commonly observed in [2+2] cycloaddition reactions, and the principles of crystal engineering can be applied to achieve desired reactivities and physical properties. Photoreactions in the solid state exhibit regio- and stereospecificity and yield quantitative photoproducts. Dynamic crystals that undergo mechanical responses to light or heat energy have emerged as smart actuating materials.

Summary: The synthesis, structure, and properties of coordination polymers composed of linear zinc bis(diorganophospate)s (ZnDOPs) were described. The morphology, thermal transformations, and solubility of ZnDOPs strongly depend on the type of organic substituent and the thermal history. ZnDOPs can undergo reversible dissociation in polar organic solvents, allowing for easy modification of their composition and properties via anion exchange.

Summary: Observing the modulation in photoactuation properties in molecular crystals sheds light on the dimerization of olefins. In this study, cocrystals of 4-styrylpyridine were examined, employing aromatic dicarboxylic acids as hydrogen bonding templates. The results showed that the effects of photodimerization were most notable in structure 3, while the effects of photosalient were most notable in structures 1 and 3. Single crystal structural analyses revealed that the efficiency of dimerization varied depending on the distance between adjacent C= C in 4-spy molecules, the parallel-to-cross arrangement ratio, and the protonation/deprotonation ratio of the pyridine moieties.

Summary: We synthesized a designed monomer with azide and alkyne units that mimic alpha-D-galactose for topochemical azidealkyne cycloaddition polymerization. The resulting cross-linkable galactan-mimic showed improved properties, such as increased porosity, particle size, and thermal stability, when covalently cross-linked using bis-dioxaborolane as the dynamic covalent cross-linker. Our findings demonstrate that topochemical polymerization can be used to create polymers with enhanced properties from naturally available feedstock materials.

Summary: We have developed a new 1,3-bis-electrophilic motif and applied it in palladium-catalyzed (3 + 2) annulations. This method offers a straightforward approach to constructing functionalized pyrrolidines with good yields. Importantly, the configuration (Z/E) of the 1,3-bis-electrophilic motif does not affect the yield and chemoselectivity of the reaction. Furthermore, preliminary asymmetric investigations using Pd(0)/thiourea synergistic catalysis resulted in moderate enantioselectivity.

Summary: In the field of supramolecules, the fabrication of polyrotaxanes or poly-pseudo-rotaxanes remains a challenge. This study reports the formation of a poly-pseudo-rotaxane in which a single salt-type guest acts as both a linking and a threading agent. The use of A1/A2-thiopyridyl pillar[5]arene (L) and silver(I) trifluoroacetate in CHCl3/CH3OH produced a one-dimensional (1D) poly-pseudo-rotaxane. Surprisingly, the AgCF3CO2 guest not only linked the di-armed L ligands but also threaded into the pillar[5]arene cavity. However, a simple 1D coordination polymer was obtained in a different solvent due to the presence of a CH2Cl2 molecule in the pillar[5]arene cavity.

Summary: Developing cost-effective, highly catalytic active, and stable electrocatalysts in alkaline electrolytes is crucial for efficient anion-exchange membrane water electrolysis (AEMWE). Metal oxides/hydroxides have emerged as promising electrocatalysts for water splitting due to their abundance and tunable electronic properties. However, achieving efficient catalytic performance with single metal oxide/hydroxide-based electrocatalysts is challenging. This review focuses on advanced strategies such as nanostructure engineering, heterointerface engineering, single-atom catalysts, and chemical modification to synthesize multicomponent metal oxide/hydroxide-based materials. The challenges and future prospects of these electrocatalysts are discussed.

Summary: Three novel hierarchical Ni-based metallosupramolecular cages were constructed using nickel ions, pyridine dicarboxylates, and isophthalate derivative ligands. These cages consist of interlinked multinuclear nickel clusters and isophthalate-derivative ligands, forming a nickel-based triple-stranded helicate and serving as supramolecular building blocks for the metallocages. The crystal packing of the racemic cages was characterized by single-crystal X-ray diffraction. Additionally, a cobalt-based molecular cage with 5-methylisophthalate bridging ligands was synthesized for host-guest interaction studies.

Summary: The preparations and structural characteristics of three-dimensional Zn(II) metal-organic frameworks (MOFs) with dipyridyl-olefin and tricarboxylate are reported. Depending on the temperature or mole-ratio variations, self-interpenetrated, noninterpenetrated, and fourfold interpenetrated structures were generated with different molecular building blocks. Interestingly, although all three MOFs contain the same metal cation, anion, and spacer ligand, they show different emissions due to structure and connectivity.

Summary: In this study, a novel bridging and fixing strategy is reported to retain the ordered arrangement of metal-organic cages (MOCs) and increase their porosity. The cages are connected by methylene bridges through electrophilic aromatic substitution reactions and formaldehyde. Pore-filling and coordinating solvents are then replaced or removed by low surface tension, noncoordinating solvents, resulting in the increased porosity of the MOCs. This method provides a simple and pragmatic approach to preserve the porosity of MOCs and extends their potential applications as functional porous materials.

Summary: This study presents the design and synthesis of sulfated disaccharide inhibitors based on IdoA(2S)-GlcNS(6S), which showed potent inhibition of Sulf-2. The results suggest that IdoA(2S)-GlcNS(6S) is the shortest fragment size required for effective inhibition of Sulfs, and a trisulfated disaccharide is identified as the minimal fragment size of heparan sulfate for effective endosulfatase inhibition.

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.
