Redox‐Modulated σ‐Bond Reactivity in a Radical‐Anion Dimer

Angewandte Chemie, EarlyView.
A radialene‐based radical anion σ‐dimer comprising an elongated C‐C bond exhibits orthogonal stimuli responsiveness. Homolytic cleavage of the dimer to the radical state is triggered by mechanical strain and high temperature. Dimer scission is also achieved via oxidation, resulting in formation of neutral radialenes.

Hole‐Activated Lattice Oxygen Enables Pt‐Free Propane Dehydrogenation by Eliminating the Hydrogen Recombination Bottleneck

Angewandte Chemie, EarlyView.
Trace Mg doping into gallia–alumina generates hole‐type oxygen species that accelerate hydrogen recombination, eliminating the need for Pt promotion. The fully oxide‐based catalyst resists sintering under repeated regeneration, outperforming benchmark PtSn and CrOx catalysts with exceptional stability over 30 dehydrogenation–regeneration cycles ...

Modifications of Lysine Residues 294 and 311 Within the Microtubule‐Binding Region Alter Tau Aggregation and Tubulin Binding Equilibria

Angewandte Chemie, EarlyView.
The molecular consequences of specific lysine modifications in Alzheimer´s disease remain insufficiently resolved in the context of full‐length protein. Here we integrate protein semisynthesis, segmental isotope labelling, and high‐resolution NMR spectroscopy to achieve residue‐resolved interrogation of site‐specific acetylation and carboxymethylation.

Activating Triplet Excitons in COFs via Layer‐Bridging Co Single Atoms for Photocatalytic H2O2 Production and Tandem C─N Coupling

Angewandte Chemie, EarlyView.
This work demonstrates a layer‐bridging coordination strategy of Co single atoms in COFs that promotes the formation and utilization of triplet excited states. The introduction of Co single atoms induces pronounced energy‐level splitting and enhanced spin–orbit coupling, facilitating the generation of 1O2 and O2•– for efficient photocatalytic H2O2 ...

Spin‐Polarized Interfaces Redirect CO2 Reduction From CO to Formate

Angewandte Chemie, EarlyView.
The chiral electrocatalyst exploits the CISS effect to establish a spin‐polarized interface that selectively promotes formate production during CO2 reduction while effectively suppressing the competing hydrogen evolution. ABSTRACT Achieving high product selectivity in electrocatalytic carbon dioxide reduction (CO2RR) remains a critical challenge due to
