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.

Uncovering Aggregation‐Induced Emission in Carbon Dots for Color‐Changing Hydrogels and Information Encryption

Angewandte Chemie, EarlyView.
Red‐emissive carbon dots (R‐CDs) exhibiting aggregation‐induced emission (AIE) and aggregation‐caused quenching (ACQ) effects are synthesized from citric acid and urea. They display weak blue fluorescence in water but strong red emission in DMF due to aggregation.

Kooperative Redox‐Katalyse der N2O‐Zersetzung mittels auf Co3O4 geträgerten RhOx‐ und CeOx‐Spezies mit kurzreichweitiger Wechselwirkung

Angewandte Chemie, EarlyView.
A short‐range Rh‐O‐Co‐O‐Ce interfacial moiety drives low‐temperature N2O decomposition via a cooperative redox cycle. Operando modulated‐excitation XAS with phase‐sensitive detection (ME‐XAS+PSD) tracks rapid, reversible Rh oxidation coupled to Co reduction. Combined kinetics and DFT rationalize the activity trends and identify the Rh‐O‐Co interface as

Structural Control of Dual Emission in Coumarin Fluorophores for Visualizing Protein Droplet Maturation

Angewandte Chemie, EarlyView.
A coumarin‐based dual‐emission fluorophore was designed to visualize the maturation of protein liquid droplets. Upon covalent conjugation to droplet‐forming proteins, ratiometric fluorescence imaging allowed real time monitoring of droplet maturation. This probe is applicable to the analysis of droplet formation and maturation mechanisms, as well as to

Synergy Between Photon‐to‐Phonon Pathway and Active Lattice Oxygen Enables Efficient and Stable Syngas Synthesis

Angewandte Chemie, EarlyView.
This work reports the design of a multifunctional MnOx support coupled with classic Rh catalytic centers for light‐driven dry reforming of methane. Benefiting from efficient photon‐to‐phonon conversion pathway and a dynamic OL‐OV cycle, the catalyst achieves high syngas production rates and light‐to‐chemical energy efficiency without external heating ...
