Summary: In this study, two new chiral CdII MOFs were characterized, which were formed through spontaneous chiral resolution during solvothermal synthesis using achiral precursors. These chiral MOFs possess infinitely-linked, chiral Cd-O helical chains, which are the apparent cause of chirality in each system. The preservation of homochirality is achieved by avoiding a physical analogue of geometric frustration.

Summary: We report the characterisation of two new chiral CdII MOFs derived from achiral precursors, showcasing the transposition of achirality to chiral structures. The MOFs exhibit chiral hexagonal and orthorhombic space groups due to the presence of infinitely-linked, chiral, and 1D Cd-O helical chains. The preservation of homochirality is attributed to the avoidance of geometric frustration caused by the tripartite nature of the underlying triangular lattice.

Summary: This study presents a novel metal/anion-coordination co-driven strategy for the synthesis of nanoscale supramolecular metallocycles with unique topology and desired chirality. The enantiomeric Janus-type metallocyclic strips are formed through the synergistic coordination of sulfate anions and Co-II ions to a bifunctional chiral ligand. The chirality is derived from two types of helical chiralities, namely triply twisted Mo''bius ring and circular helicate, which represent a new phenomenon in metal-organic complex systems.

Summary: The study found that in the presence of lactic acid enantiomers, three-dimensional chiral 3d-4f heterometal-organic frameworks can be formed and spontaneously resolved from achiral ligands, while in the absence of lactic acid enantiomers, the reactants randomly generated both enantiopure crystals. The enantiopure lactic acid induced asymmetric resolution to achieve single chiral crystallization. DFT theoretical calculations showed that the absolute chiral resolution of the enantiomers is due to the difference in the interactions between the two enantiomeric units and the chiral inducer.

Summary: In this study, we achieved the expression and amplification of chirality in 2D metallosupramolecular networks formed by a nucleobase derivative. A racemic compound was obtained in the absence of coordinating metal ions, but spontaneous resolution occurred upon the addition of a coordinating ion or suitable guest molecule. The use of enantiopure solvent broke the mirror symmetry and resulted in a globally homochiral surface.

Summary: In this study, Anderson-Evans type polyoxometalates modified with anthracene groups were successfully synthesized and used for the construction of chiral hexamers. The chiral hexamers maintained their structure stability in organic solvents and were characterized by physicochemical measurements. Crystal data analysis revealed that the chirality of the hexamers originated from the arrangement of twenty Na-O subclusters. When a non-chiral linker was used, a one-dimensional supramolecular polymer chain was formed.

Summary: Nonconjugated polymer dots (NPDs) were utilized as fluorescent probes to selectively and sensitively detect picric acid (PA), demonstrating high sensitivity and selectivity in environmental monitoring. The fluorescence of NPDs was efficiently quenched by PA through the inner filter effect, attributed to the overlapping absorption band of PA and excitation spectrum of NPDs.

Summary: Incarcerated gravid uterus is a rare obstetrical complication that can lead to adverse outcomes, with approximately 1 in 2300 pregnancies remaining incarcerated at term or near-term. Spontaneous resolution was observed in 78.5% of cases after 16 weeks of gestation. Expectant management may be an option in cases where there are no severe symptoms related to the incarceration itself.

Summary: Gold(II) complexes have been less utilized in catalysis compared to their gold(I) and gold(III) counterparts. However, gold(II) complexes offer potential in homo-coupling and cross-coupling reactions, as they are more easily accessible through simplified oxidation and reduction processes. Gold(II) exhibits characteristics of both soft acid gold(I) and hard acid gold(III). This review explores the unique reactivity and potential applications of gold(II) species, highlighting their significance in catalytic transformations.

Summary: A new aryl selenonium polyoxometalate hybrid was developed and compared with an aryl sulfonium polyoxometalate hybrid in terms of their photocatalytic properties. It was found that the aryl selenonium hybrid exhibited better catalytic performance, which could be attributed to the larger atomic radii of selenium stabilizing the photogenerated electron-hole pair more efficiently. Additionally, the generation of elemental selenium through cleavage of C-Se bonds during catalysis was observed.

Summary: Na-ion batteries (NIBs) have attracted great interest as a potential technology for grid-scale energy storage due to the wide distribution, low cost, and environmental friendliness of sodium resources. However, their implementation is hindered by low rate capability and cycling stability caused by the large ionic size of Na+.
