Photoredox Catalysts Based on N‐(Hexyl)benzothioxanthene‐3,4‐dicarboximide for Photopolymerization and 3D Printing Under Visible Light

Angewandte Chemie, EarlyView.
In this work, two benzothioxanthene imide dyes demonstrate excellent photochemical properties. When used as photocatalysts, they work with amine and iodonium salt or sulfonium salt to form different three‐component systems for effectively initiating photopolymerization under visible light, through photoredox catalysis processes.

Leveraging Noncovalent Interactions for the Binding of CO by a Weakly Lewis Acidic Borane

Angewandte Chemie, EarlyView.
We report a carbonyl complex featuring a simple tri‐coordinate borane, characterized by a Lewis acidity which is only marginally higher than B(NMe2)3. Exposure of {(Ph2P)xanth}3B to carbon monoxide under mild conditions (1 bar, 25 °C) reversibly yields {(Ph2P)xanth}3B·CO.

Azobenzene‐Oxindole Photochromic Dyads

Angewandte Chemie, EarlyView.
A novel photochromic azobenzene‐oxindole dyad is reported. The combination of the two switches promotes drastic molecular geometry changes and allows for precise NMR quantification. This enables the study of the photokinetic behavior under different irradiation conditions and the discovery of a unique photokinetic relationship between the two ...

LC‐MS and High‐Throughput Data Processing Solutions for Lipid Metabolic Tracing Using Bioorthogonal Click Chemistry

Angewandte Chemie, EarlyView.
This study introduces an integrated analytical and bioinformatics platform for high‐throughput tracing of lipid metabolism using bioorthogonal alkyne fatty acids and optimized LC‐MS workflow. Applied to human fibrosarcoma cells, the method traced fatty acid metabolism, revealing nuances in sphingolipid routing and metabolic bottlenecks, highlighting ...
