Angewandte Chemie, EarlyView.A five‐membered digermacycle exhibits an unusual 4π electron delocalization enabled by σ*(Ge–C)–π coupling within a nearly planar framework. Combined experimental and theoretical analyses reveal a continuous cyclic delocalization pathway, highlighting σ*–π interactions as a design principle for aromatic stabilization beyond classical π‐conjugated ...

Structural Insights Into Man9 Recognition by the HIV Antibody 2G12 Revealed by Paramagnetic NMR
Advanced Science, EarlyView.The HIV gp120 glycoprotein displays Man9 oligomannose structures that are recognized by the neutralizing antibody 2G12. Detailed characterization of the binding epitope in solution is important for immunogen design but remains challenging, since the signals of the terminal mannoses from the three arms of Man9 (D1, D2, and D3) cannot be distinguished in

Acta Crystallographica Section E: Crystallographic CommunicationsThe reaction of dibenzonorcarynyliden(e/oid) with phencyclone was recently reported to give a congested spiropentane with endo stereochemistry. Herein we report that, in sharp contrast, an analogous reaction using tetracyclone, instead of phencyclone ...

Advanced Science, EarlyView.SPARK decodes structure‐property relationships in anion exchange membranes (AEMs) via a chemically informed dual‐channel graph attention network (DEGAT) that explicitly captures microphase separation. It outputs five‐level grades for hydroxide conductivity and alkaline stability and highlights relevant key structural units, enabling robust pre ...

Chiral‐Encoded Pt‐Ir Surfaces as Apparent Spin Filter for Enhanced Oxygen Reduction
Advanced Science, EarlyView.The Chiral‐Induced Spin Selectivity (CISS) effect is employed in chiral‐encoded mesoporous Platinum‐Iridium (Pt‐Ir) electrocatalysts to enhance the oxygen reduction reaction (ORR). A break in spin symmetry leads to a substantial antagonistic difference in activity (>200%) when comparing two enantiomorphs of the same electrode.
