Summary: Pyridine-boryl (py-boryl) radicals act as efficient electron-doping reagents for single-walled carbon nanotubes (SWCNTs) by transferring electrons from the py-boryl radical to the SWCNT. The formation of a stable py-boryl cation is crucial for effective doping, with the captodative effect of the py-boryl cation playing a key role in this process.

Summary: The chemistry of low valent p-block metal complexes is of great interest due to their reactivity that surpasses that of d-block metal complexes. The introduction of aluminyl anions, complexes with a negatively charged Al(I) center balanced by an alkali metal cation, has opened up a new area of chemical research. Aluminyl compounds exhibit diverse reactivity towards small molecules and functional groups. This article presents an account of the structure and reactivity of aluminyl compounds, investigating the relationship between aluminyl anions and alkali metal cations. It also discusses the potential application of these compounds in chemical synthesis.

Summary: This contribution describes the formation of homonuclear sigma bonding between boron mediated by alkaline earth metals. The reaction between alkaline earth bis-(trimethylsilyl)amides and bis(pinacolato)diboron resulted in the formation of group 2 silazide diborane adducts. Further reaction with bis(pinacolato)diboron led to the formation of bis-triboranate derivatives. These complexes provide rare examples of catena-boron species with propagated B-B bonds beyond the common diboranes.

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: In this work, two metal organic frameworks (MOFs) containing {Cu2I2} clusters, Eu-CuI-INA and Sr-K-CuI-INA, were synthesized and characterized. Both materials have a three-dimensional structure with {Cu2I2} clusters coordinated by INA(-) ligands and Eu3+ or Sr2+ ions. The Sr-K-CuI-INA material exhibited sensitive fluorescence sensing behaviors towards cysteine and nitro-bearing molecules, showing potential applications in bio and explosive molecule sensing. This work provides a good reference for designing fluorescent MOF probes containing CuI molecules.

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+. In this study, a three-dimensional nanoarchitectured coral-like CoSe2@N-doped carbon (CL-CoSe2@NC) was synthesized, and it exhibited improved sodium storage properties with better electrode kinetics and a stable SEI film.
