Bulletin of the Korean Chemical Society, EarlyView.The development of organic solar cells (OSCs) has been driven by structural modifications of Y6‐series non‐fullerene acceptors. In particular, side‐chain engineering regulates solubility, molecular packing, and energy levels, enabling efficiencies to increase from 15.7% to over 20%.

Carbon Energy, EarlyView.Beyond the hype surrounding the self‐healing properties of gallium‐based liquid metals (Ga‐LMs), this perspective critically examines their functional roles in metal‐ion batteries, highlighting both their underlying merits and the often‐overlooked challenges, including non‐representative design and testing configurations, performance overestimations ...

Chemistry – A European Journal, EarlyView.ABSTRACT Inorganic analogues of aromatic compounds, wherein C═C bonds are replaced with B─N bonds, are isoelectronic with the original aromatic compounds, however, they can show different properties. While borazine, an inorganic analogue of benzene, has been well‐studied, inorganic analogues of chalcogenophene have been less explored.

Cationic Sulfonium‐Based Tripodal Ligand and Its Rh(I) Complexes
Chemistry – A European Journal, EarlyView.We report a cationic EP3‐type tripodal ligand based on an aromatic sulfonium cation (E = S+) along with a series of its Rh(I) complexes. Structural, spectroscopic, electrochemical, and computational analyses of these complexes compared to isostructural analogs (E = Si− or P) reveal pronounced electron density depletion at Rh in the sulfonium congener ...

N─H or O─H Bond Activation With a Bicyclic Si4 Ring Compound
Chemistry – A European Journal, EarlyView.The bicyclic Si4 ring compound with zwitterionic character reacts with NH3, H2O, and selected alcohols to give functionalized saturated silicon rings, siliconoid clusters with unsubstituted Si atoms, or simple 1,3‐addition products. The experimentally observed reactivity could be rationalized based on results from mechanistic calculations employing ...

A persistent germylyne radical enabling reversible σ-dimerization and diverse bond activation
Nature CommunicationsThe reversible σ-dimerization of radicals is a fundamental process in bond formation and cleavage, yet achieving this with an isolable heavy carbyne analogue has remained a paramount challenge.

Deriving General Energy Predictors for Pnictogen Bonding
Chemistry – A European Journal, EarlyView.This study derives general energetic predictors for pure pnictogen bonds from nitrogen to bismuth based on the potential energy density at the bond critical point. The research highlights the increasing occurrence of secondary interactions for heavier elements.

Multi‐state Photoswitching in Thienoquinoid‐Based Fluorescent Trithiophenes
Chemistry – A European Journal, EarlyView.A methine‐bridged trithiophene with a thienoquinoid core undergoes photoisomerization of both C═C bonds, affording three geometrical isomers in a ratio controlled by the irradiation wavelength. Despite full π‐conjugation, the system retains fluorescence, enabling wavelength‐addressable multi‐state switching with luminescent readout.
