Activation of Aryl Halides by Triplet–Triplet Annihilation Upconversion Enabling Coupling Processes Under an Open‐to‐Air Environment

open access: yesEuropean Journal of Organic Chemistry, Volume 29, Issue 24, 23 June 2026.
Triplet–triplet annihilation upconversion (TTA‐UC) performed inside supramolecular viscoelastic gels enables efficient CC and C–heteroatom coupling reactions under green LED irradiation in open‐air conditions. The gel network restricts oxygen diffusion, preserves triplet states, and allows aryl halide activation through upconverted excited states ...

Proline Ring‐Inversion Dynamics in Peptides Enable Cross‐Relaxation‐Based Dynamic Nuclear Polarization

open access: yesChemPhysChem, Volume 27, Issue 11, 15 June 2026.
A systematic investigation of SCREAM‐DNP beyond methyl groups, using ring‐inversion dynamics on proline as a model compound. Comparison between free proline and proline‐containing oligopeptides at different sequence positions shows how local structural context modulates ring dynamics and site‐specific DNP enhancement.

Monitoring Redox Pathways and Performance Limitations in Lithium‐Sulfur Batteries Using In Situ 7/6Li and 33S NMR Spectroscopies

open access: yesAngewandte Chemie, Volume 138, Issue 24, 8 June 2026.
Lithium‐sulfur (Li‐S) batteries contain various NMR‐active nuclear isotopes, including 7Li, 6Li and 33S, which are sensitive to the different chemical reactions that occur during battery cycling. Herein, we use a combination of lithium and sulfur operando NMR spectroscopy to provide new insights at the molecular level, fundamental understanding being ...
