Mechanophotochemistry: Lighting up EDA Complexes in the Solid State

Angewandte Chemie, EarlyView.
Examples of mechanophotochemical EDA complex‐mediated radical reactions, including a Giese reaction, a C─S cross‐coupling reaction, a phosphorylation reaction, and a sulfonylation reaction are shown to rapidly proceed in air using visible light excitation.

Chalcogen‐Bond‐Driven Electrochemical Bromide Sequestration in Benzothiazole‐Functionalized Covalent Organic Frameworks

Angewandte Chemie, EarlyView.
To address the unresolved challenge of selective bromide removal from reverse‐osmosis permeate, we developed benzothiazole‐functionalized COF/rGO electrodes that exploit directional chalcogen bonding to preferentially capture Br− over Cl−. The mesoporous BTzTp@rGO electrode achieved a maximum Br− uptake of 36.7 mg g−1, a Br−/Cl− selectivity factor of ...

Fine Tuning of Catalyst Active Sites to Access Advanced Ultrahigh‐Melting Polyolefins

Angewandte Chemie, EarlyView.
A redesign of the active site of the pyridylamido hafnium (Hf) catalysts can enhance the performance of this catalyst family and unlock previously inaccessible polymer structures. When the catalyst is precontacted with allyltrimethylsilane the active species is modified and the catalyst experiences a new life becoming able to polymerize sterically ...

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

Angewandte Chemie International Edition, Volume 65, Issue 44, 26 October 2026.
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.
