Summary: Depending on the size and basicity of the anion, the self-assembly of 2,5-diformylpyrrole, tris(2-aminoethyl)amine, and silver(I) resulted in new cascade complexes or plenates, which are cryptates incorporating Ag-n(n+) clusters. The nature of the product was determined by the counterion and its formation was driven by either cascade anion binding or argentophilic interactions stabilizing the cluster within the cavity. The reaction of plenates with tetrabutylammonium halides led to the protonation-coupled replacement of the Ag-3(3+) with anion(s), forming cascade cryptates.

Summary: We synthesized and characterized four new copper(II) complexes with 2-hydroxypyridine in its lactam tautomeric form (2-pydo) and 4-hydroxypyridine in both lactim (4-hpy) and lactam (2-pydo) tautomeric forms. The complexes were structurally characterized by single-crystal X-ray analysis and FT-IR spectroscopy. Magnetic measurements showed a magnetic moment of approximately 1.7 BM for Cu2+ at room temperature, as expected. Thermal analysis demonstrated the formation of nanosized elemental copper when heating the compounds to 600 degrees C in nitrogen, consistent with literature reports on similar compounds.

Summary: The first oligopyrrolic Cu(ii)-based metallocage with two antiferromagnetically coupled dimeric cupric tetracarboxylate units linked by a single molecule of water was successfully assembled using a nonlinear pyridine-pyrrolate ligand. Broken symmetry density functional theory (BS-DFT) calculations showed that the exchange couplings between Cu(ii) ions in the Cu-2 unit and over the water bridge were -298 and -0.13 cm(-1), respectively.

Summary: This study presents the self-assembly and structure of a multi-metallic motif-based Cu-II metal-organic cage (MOC) functionalized with free bis(pyrazolyl)methane sites. PdII chloride can be quantitatively inserted into the MOC, resulting in a heterometallic cage structure. The choice of solvent in the metalation process determines the solid-state isomerism of the cage, providing a means to control the MOC's structural diversity and permanent porosity.

Summary: In this study, binuclear copper(I) complexes of P,N-containing cyclophanes with two 1,5-diaza-3,7-diphosphacyclooctane rings incorporated into a macrocyclic core were synthesized. The structure of one complex was determined by X-ray diffraction analysis, and the complexation caused a slight distortion of the cyclophane conformations.

Summary: Using different evaporation rates of the dispersion solvent, controlled assembly of CsPbBr3 nanoplatelets was achieved. Electron microscopy, X-ray scattering, and diffraction confirmed the superlattice structures in both the face-down and edge-up configurations. Polarization-resolved spectroscopy revealed significantly polarized emission in the edge-up superlattices compared to the face-down counterparts. Variable temperature X-ray diffraction revealed a uniaxial negative thermal expansion in ultrathin nanoplatelets, explaining the anomalous temperature dependence of the emission energy. Additional structural aspects were investigated by multilayer diffraction fitting, showing a decrease in superlattice order and an expansion of the organic sublattice and lead halide octahedral tilt with decreasing temperature.

Summary: The emerging field of molecular cybernetics has the potential to broaden our understanding of chemistry, beyond its focus on single transformations, pure compounds, and mixtures. Chemistry will become autonomous, networked, and intelligent through communication between molecules, each serving a control engineering purpose.

Summary: We demonstrate the locomotion capabilities of a biped on a tetrahedral track using chemical fuel, cooperative binding, and kinetic selectivity. The biped's movement is enabled by the binding of its dibenzyl amine feet to zinc porphyrin units and the subsequent protonation and binding to dibenzo 24-crown-8 sites, forming pseudorotaxane linkages.

Summary: This study investigates the enhancement of emission of aggregation-induced emission (AIE)-active molecules in dilute solution by restricting intramolecular motion (RIM). A Pd-4 molecular vessel (MP1) was assembled to restrict the active intramolecular motions of AIE active molecule SG. SG showed significant enhancement in emission in dilute solution upon addition of MP1. This strategy has the potential to design materials for high emission in the aggregated state as well as in dilute solution.

Summary: Research on self-assembled metallosupramolecular architectures has seen a recent surge. A unique class of triazine based immidazolium water-soluble metal-free interlocked organic cage was successfully synthesized without the use of dynamic covalent chemistry or chromatographic separation. An analogous non-interlocked cage was also achieved by steric control using different positional isomers of the building blocks.
