Summary: The reaction between differently substituted borasiloxanes and 2,5-bis(3-pyridylethynyl)thiophene resulted in the formation of luminescent borasiloxane-based chiral helices held together by N-B bonds, which were fully characterized along with the starting building blocks. The nature of the N-B bond was rationalized through theoretical calculations.

Summary: Materials that can undergo reversible changes typically require top-down processing for microstructure programming, making it difficult to program microscale 3D shape-morphing materials that deform in non-uniaxial ways. However, a new bottom-up approach is described here, using liquid crystal monomers with controlled chirality to create bending microactuators. By adjusting the concentration of chiral dopants, the bending behavior of these microactuators can be controlled. The asymmetric molecular alignment within the 3D structure confirms the effectiveness of this fabrication method.

Summary: Chiral coordination polymers and porous chiral MOFs have great potential for enantioselective separations, sensing, and catalysis due to their well-structured internal chiral cavities. Various synthetic approaches have been developed over the past two decades, with a focus on using enantiopure ligands to yield homochiral network solids that influence the applications of these materials. Despite being a mature field, there is still huge potential for functional chiral materials, and areas ripe for exploration are highlighted.

Summary: Two thiacalix[4]arene-protected silver(I) alkynyl nanoclusters, Ag-9 and Ag-18, were synthesized and characterized. The structural unit of these nanoclusters migrated in different modes under the influence of different coordination ions, resulting in different Ag.Ag distances. Both nanoclusters exhibited good solution stability and their fluorescence responses were influenced by the polarity of the solvent.

Summary: The metal-induced self-assembly strategy promotes the pi-dimerization of viologen-based radicals, forming discrete box-shaped 2:2 macrocycles or coordination polymers. Changing the redox state of the tectons leads to reversible inflation/deflation of the macrocyclic assemblies, with viologen-centered electron transfer triggering dissociation of coordination polymers. The driving force of the disassembling process is the formation of stabilized 2:2 assemblies through pi-dimerization of viologen cation radicals.

Summary: Metal-organic frameworks (MOFs) are porous materials with potential applications in gas separation, drug delivery, sensing, and catalysis. This study demonstrates that increasing the reaction concentration during the synthesis of MOFs leads to the unexpected trapping of a new framework called CORN-MOF-1. The structure of CORN-MOF-1 is similar to that of known MOFs, but with partially protonated linkers and charge-balancing or coordinated formate groups. CORN-MOF-1 exhibits strong photoluminescence in the solid state, while other MOFs show weak emissive properties due to excimer formation.

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: 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.
