Diazirines Beyond Photoaffinity Labeling: A Comprehensive Overview of Applications in Biological Sciences, Materials Chemistry, and NMR‐Spectroscopy

open access: yesAngewandte Chemie, Volume 138, Issue 4, 22 January 2026.
Diazirines are three‐membered, nitrogen‐containing heterocycles that decompose under light or heat to generate carbenes. For the past two decades, they have served mainly as minimally invasive tags in photoaffinity labeling (PAL). More recently, their value as versatile carbene precursors has been recognized.

Universal Fluorine‐Free Proton Exchange Polymers for High‐Performance and Durable Fuel Cells Operable Under Severe Conditions

open access: yesAdvanced Materials, EarlyView.
Due to excellent physical and chemical stability, the novel designed fluorine‐free polymers with aliphatic‐chain backbones (SP‐PAC12‐QP) are regarded as promising and universal alternatives to perfluorosulfonic acid membranes. Their performances are further improved by physical reinforcement, where the fuel cell performance under high temperature and ...
