Cucurbit[7]Uril‐Based Supramolecular Polymers With Dual Photochromism and Fluorescence: From Host‒Guest Design to Smart Applications

Aggregate, EarlyView.
The supramolecular complexes of cucurbit[7]uril with thiophene‐pyridinium guests formed by different assembly ratios exhibit different photochromic and fluorescence properties, which render them suitable for applications in multi‐level anti‐counterfeiting and advanced information encryption.

Real‐Time Eco–AI, Electrophoresis‐Correlative Data‐Dependent Acquisition with AI‐Based Data Processing Broadens Access to Single‐Cell Mass Spectrometry Proteomics

Angewandte Chemie, EarlyView.
An affordable single‐cell proteomics workflow combines capillary electrophoresis, real‐time ion sorting, and AI‐aided spectral deconvolution to profile early Xenopus embryonic cells. Despite using a legacy Orbitrap, this strategy matches or exceeds the sensitivity of modern instruments, uncovering proteome dynamics at sub‐nanogram scale.

Natural Polyphenol–Metal Supramolecular Nanocomplex for Ferroptosis Activation in Chemoresistant Hepatocellular Carcinoma

Aggregate, EarlyView.
This study presents a supramolecular nanocomplex assembled from a natural polyphenol and Cu(II) that enables cascade glutathione (GSH) depletion through synthesis inhibition, redox cycling, and Michael addition. The system induces dual cytoplasmic and mitochondrial ferroptosis in cisplatin‐resistant hepatocellular carcinoma (HCC), reverses drug ...

Mechanistic Divergence in Sulfur‐Ligated Iron(III)‐Alkylperoxo Reactivity: Aldehyde Oxidation Prevails over Deformylation

Angewandte Chemie, EarlyView.
This study explores the mechanistic investigation into an unusual reactivity of a thioether‐ligated low‐spin Fe(III)‐alkylperoxide with cyclohexane–carboxaldehyde as a mimic of nonheme iron(II) enzyme intermediates and highlights that only efficient catalysis happens from a high‐valent iron(IV)‐oxo species.
