Dispersion‐Enhanced Nitrogen‐Centered Photocatalysis of the Direct Hydrogen Atom Transfer
Angewandte Chemie, Volume 138, Issue 6, 2 February 2026.Nitrogen‐centered acridine photocatalysts for direct hydrogen atom transfer have been developed, leveraging dispersion interactions to enhance photocatalytic activity. This approach enables diverse functionalization reactions of strong C─H bonds even under cryogenic conditions and provides a new strategy for boosting the efficiency of direct HAT ...

Small, EarlyView.The development of gated systems enabling controlled pore opening offers new opportunities for sensing applications. This study explores dye loading in porous and non‐porous cerasomes and pH‐dependent ATP‐triggered gating via polyamine anchors. Porous cerasomes were synthesized using block‐co‐polymers, enabling controlled proton influx and fluorescence‐

Counterion Effects on the Properties and Reactivity of Charged Photoredox Catalysts
ChemPhotoChem, Volume 10, Issue 8, August 2026.The choice of a counterion for a charged photocatalyst has long been overlooked. In this review, we summarize recent reports on counterion effects in photocatalysis, providing readers with a comprehensive theoretical understanding and synthetic applications for the use of a carefully chosen counterion. Electrostatic interactions represent the strongest

ChemistryOpen, Volume 15, Issue 7, July 2026.Selective monosubstitution in cyclooctane dimesylates is investigated by DFT calculations. Despite favorable SN2 conditions, the second substitution is suppressed due to increased activation strain and unfavorable conformational reorganization. The results reveal that intrinsic structural constraints, rather than external factors, govern reactivity ...

, 2016 Seven-membered lactones undergo selective SmI2–H2O-promoted radical cyclization to form substituted cyclooctanols. The products arise from an exo-mode of cyclization rather than the usual endo-attack employed in the few radical syntheses of cyclooctanes.

Chemistry – A European Journal, Volume 32, Issue 22, 9 June 2026.Ir pincer complexes bearing a triazole architecture in the pincer backbone and O‐ancillary chelating ligands are presented. These were employed in the catalytic transfer dehydrogenation of alkanes as well as of saturated heterocycles. Reactivity of these complexes with silver salts and Lewis acids produced various cationic iridium complexes.
