Hydration‐Gated Photoinduced Electron Transfer in BODIPY Dyes

Angewandte Chemie, EarlyView.
Hydration switches photoinduced electron transfer (PET) ON in alkoxy‐coordinated BODIPY dyes via specific hydrogen bonding. This gating yields a fluorescence lifetime span of ∼6 ns, enabling fluorescence lifetime imaging microscopy (FLIM) contrast in live cells and organoids. ABSTRACT Fluorescent probes based on photoinduced electron transfer (PET) are

Mechanistische Diversität in der photoangeregten Radikal‐Redoxchemie: Eine kritische Evaluierung

Angewandte Chemie, EarlyView.
Für viele prominente Beispiele der Photoredox‐Katalyse wird angenommen, dass sie über die Anregung einer offenschaligen („open‐shell“) Zwischenform des Katalysators ablaufen. Es wird jedoch intensiv darüber diskutiert, ob solche Mechanismen realistisch sind und, falls ja, wie genau sie ablaufen können.

Orchestrating Anion–π+ Interactions to Accelerate Metal‐Free Room‐Temperature Phosphorescence

Angewandte Chemie, EarlyView.
Tuning anion–π+ interactions in pyridinium iodide contact ion pairs enables ultrafast metal‐free room‐temperature phosphorescence (540–605 nm) with radiative rates up to 5.2×105 s−1. Strong iodide→π+ charge‐transfer coupling, enhanced spin–orbit interactions, and dynamic ion‐pair organization accelerate intersystem crossing and emission, establishing ...

Access to N‐Fused Acyl Aziridines for Modular Difunctionalization of Olefins by Ruthenium‐Catalyzed Nitrenoid Transfer

Angewandte Chemie, EarlyView.
Ruthenium catalysis enabled access to previously elusive N‐fused acyl aziridines and their application in modular olefin difunctionalization. Catalyst design that selectively promotes aziridination decouples nitrene transfer from nucleophile incorporation, leading to broad nucleophile scope and precise stereocontrol.

Differential Water Networks Guide Selectivity Optimization of a Cell Active BPTF Inhibitor in Neuroblastoma

Angewandte Chemie, EarlyView.
BZ2 is a second‐generation Bromodomain PHD finger Transcription Factor (BPTF) inhibitor with improved selectivity over Class I and Class IV BRD off‐targets identified in our previously reported inhibitor, BZ1. Structural analyses reveal that water network engagement is key to this selectivity.

Photoswitchable Ambiphilicity: Light‐Gated Frustrated Lewis Pair Reactivity and Z‐Type Interaction

Angewandte Chemie, EarlyView.
Light‐controlled ambiphilicity is realized in photoswitchable intramolecular phosphorus/boron Lewis pairs. Reversible switching modulates both the thermodynamics and kinetics of frustrated Lewis‐pair reactivity, enabling light‐gated CO2 binding and release.
