This study reports the first cationic chalcogenaboranes that retain the same skeletal electron pair count as their neutral counterparts, defying Wade’s rules. The ionization significantly enhances their electrophilicity, enabling reactions with very weak bases. Furthermore, it allows for regioselective control over interactions with hard and soft bases by modulating the LUMO. https://onlinelibrary.wiley.com/doi/10.1002/anie.202419677

This study presents the synthesis and structural modification of a silver-based nanocluster [Ag17(o1-CBT)12]3- (Ag17) by incorporating Au and Cu at specific sites, forming AuAg16, Ag13Cu4, and AuAg12Cu4. These modifications systematically alter their structural, electronic, and optical properties, with Au stabilizing the core and Cu enhancing photoluminescence and prolonging excited-state lifetimes. The study demonstrates a tunable […]

The macropolyhedral compound anti-B18H22 was long thought to be the only boron hydride compound that exhibited fluorescence when illuminated with ultraviolet light. We have recently shown that new and, indeed, some previously known macropolyhedral compounds, containing sulphur or selenium, and exhibiting a wide range of structural types, possess luminescent properties. https://onlinelibrary.wiley.com/doi/full/10.1002/ange.202401872
