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

open access: yesAngewandte 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.

Protonation‐Gated Orthogonal Control of Highly Efficient Molecular Motors With Broad Visible‐Light Responsiveness

open access: yesAngewandte Chemie, EarlyView.
Reversible protonation gates coumarin‐based overcrowded‐alkene molecular motors by dynamically reshaping their conjugation topology. This strategy enables efficient, near‐quantitative unidirectional photoisomerization from blue–green to red‐shifted visible light up to 600 nm, while preserving motor function and allowing orthogonal light, heat, and acid/

Erste Hinweise auf Ozonido‐TMC‐Komplexe von Eisen und Kobalt

open access: yesAngewandte Chemie, EarlyView.
Die Umsetzung der Eisen(II)‐Komplexe [(TMC)Fe(OTf)]BArF und [(D12‐TMC)Fe(OTf)]BArF sowie der Kobalt(II)‐Komplexe [(TMC)Co(OTf)]BArF und [(D12‐TMC)Co(X)]BArF (X = OTf, F) mit Ozon führt in einem 4:1‐Gemisch aus 2‐Me‐THF und THF bei Temperaturen bis −155°C zur Bildung von Ozonido‐ und Oxido‐Komplexen.

Molecular Engineering Boosts Photon‐Activated Immunotherapy for Prostate Cancer Through Concurrent Pyroptosis and cGAS‐STING Pathway Activation

open access: yesAngewandte Chemie, EarlyView.
The engineered DTSe‐based photosensitizer, DZTSe, emerges as an avant‐garde molecular entity, which can distribute to both the endoplasmic reticulum and mitochondria to concurrently trigger pyroptosis and activate the cGAS‐STING pathway. This dual‐action strategy effectively reprograms the tumor microenvironment, enabling potent eradication of primary ...

Precision Switching and Coupled Motion in a [3]Rotaxane Molecular Machine

open access: yesAngewandte Chemie, EarlyView.
A [3]rotaxane, composed by two crown ether macrocycles and an axle presenting three recognition sites, is operated through both chemical and electrochemical stimuli. The position of the macrocycles is precisely controlled by sequential stimulation and the processes are fully reversible. The characterization of the system revealed the macrocycles affect
