Summary: Large S-8-corona[n]arene macrocycles with alternating aryl and 1,4-C6F4 subunits were successfully synthesized on large scales using new high acceleration SNAr substitution protocols. The size and functionality of the macrocycles can be adjusted by selecting the appropriate precursor and catalyst. Furthermore, the inclusion of solvent controls the conformation and fluorine-fluorine interactions of the macrocycles, leading to spontaneous self-assembly into honeycomb-like lattices.

Summary: This paper reports the synthesis and X-ray characterization of two derivatives containing the four most abundant halogen atoms, aiming to study Ha···Ha halogen bonding interactions. The heavier halogen atoms exhibit anisotropy of electron density, leading to the formation of multiple Ha···Ha contacts in the solid state. The halogen bonding assemblies in both compounds were analyzed using various methods such as DFT calculations, MEP surfaces, QTAIM, NCIplot, and ELF.

Summary: Metal-organic frameworks can be fine-tuned by adjusting the metal-ligand combination, and ligand isomers can be used to synthesize frameworks with new properties and topologies. In this study, ten lanthanide frameworks were synthesized using the cis-stilbene derivative ligand, resulting in five 2D sheet structures and five 3D frameworks with microporous channels. These frameworks exhibit a previously unrecognized underlying net topology, designated as lmj1.

Summary: A new polycationic pseudo[1]rotaxane was successfully synthesized through hydrazone bonds, self-assembled in excellent yield in aqueous media. The thermodynamically controlled process involves the [1 + 1] reaction of a bisaldehyde and a trishydrazine, formation of the macrocyclic part, conversion into pseudo[1]rotaxane, and the one-pot [1 + 1 + 1] condensation process. The obtained molecule exhibited the ability to form self-inclusion complexes and supramolecular aggregates in different concentration ranges.

Summary: Self-assembly relies on the ability of smaller entities to arrange into organized systems, with the design of the media playing a crucial role. The media determines the self-assembly pathway and can control the wrapping process of supramolecular homo-aggregates by a different crystal lattice component. This reverse coating process is controlled by the media composition and could lead to the construction of hierarchical supramolecular structures.

Summary: We have derived design principles for assembling rectangular tetramines into Zn8L6 pseudo-cubic coordination cages. The ligand panels' rectangular geometry and the handedness of each metal center at the corners of the pseudo-cube result in multiple possible cage diastereomers. However, our experiments showed that each tetra-aniline subcomponent assembled with zinc(II) and 2-formylpyridine into a single Zn8L6 pseudo-cube diastereomer. The preferred diastereomer depended on the subcomponent's aspect ratio and conformational flexibility.

Summary: A thermal gradient method was used to synthesize three novel lead mixed-ligand coordination polymers, which were structurally characterized by single crystal X-ray diffraction and their thermal behavior was identified by thermogravimetric analysis. Compounds 2 and 3 were also prepared by an ultrasonic process and characterized by IR spectroscopy, powder X-ray diffraction, and scanning electron microscopy. The particle size and morphology of compounds 2 and 3 were examined by changing the initial concentration of reagents, time, and ultrasonic power.

Summary: Terminal ligand exchange and framework linker exchange are powerful tools for functionalizing reticular structures like MOFs, with kinetic analysis showing adaptive linker installation is faster than isometric linker exchange. In this study, a 6-connected layered MOF was postsynthetically modified to achieve a 12-connected fcu framework through simultaneous isometric linker exchange and linker installation between layers. Adaptively reorganized domains create sites for new linker installation, gradually transitioning to dominate the crystal structure.

Summary: The study used in situ synchrotron X-ray scattering analysis to evaluate the binding sites for reagent and product molecules near catalytic Ni-oxo clusters in NU-1000 with different surface functionalization, showing a correlation with ethylene hydrogenation activity. The most active catalyst had ethylene reagent molecules binding close to the catalytic clusters only at temperatures near the experimentally observed onset of catalysis, while ethane product molecules favored a different binding location.

Summary: In this study, MnCo2S4 nanosheet catalyst was successfully synthesized and found to exhibit superior performance in hydrogen evolution. Compared to MnCo2S4, MnCo2S4 showed low overpotentials, moderate Tafel slope, and excellent sustainability. The outstanding performance can be attributed to the increased number of electrochemically active sites and enhanced electronic conductivity on the catalyst surface.
