Theretofore Highest Efficiency in Vacuum‐Deposited Organic Solar Cells Originating From Triarylamine‐Based Small‐Molecule Donors Containing Fused Heterocycle Units

Advanced Science, EarlyView.
Fused‐ring engineering unlocks record efficiency in vacuum‐deposited organic solar cells. By replacing linear π‐bridges with fused‐ring analogues in triarylamine‐based donors, we achieve enhanced molecular planarity, red‐shift optical absorption, minimize energy loss and optimized phase separation.

Isomeric Ag14 Nanoclusters With Distinct Photophysical and Nanomechanical Properties

Advanced Science, EarlyView.
Ligand‐shell isomerism in atomically precise Ag14 nanoclusters is demonstrated to regulate core distortion, photoluminescence, and mechanical properties. Subtle changes in phosphine ligand arrangement drive a pronounced emission shift from green to red and alter crystal rigidity, revealing a direct structure‐property correlation that offers new design ...

Pyrazole‐Derived Antibacterial Compounds Effectively Treat Methicillin‐Resistant Staphylococcus Aureus Infections by Inhibiting Aspartate Transcarbamoylase

Advanced Science, EarlyView.
This study unveils a novel antibacterial mechanism against MRSA, in which the compound Py‐27 selectively targets and inhibits aspartate transcarbamoylase (ATCase), a key enzyme in pyrimidine synthesis. This inhibition disrupts DNA replication, induces oxidative damage, leading to potent bactericidal activity.
