Photoredox‐Catalyzed Synthesis of a Novel Class of Fluoroalkyl Pyrazolones

Advanced Synthesis &Catalysis, EarlyView.
A photoredox strategy enables regioselective synthesis of fluoroalkyl 2‐pyrazolin‐5‐ones via radical addition and cyclization. This mild, metal‐free method shows a broad substrate scope, operates in batch and flow systems, and offers a sustainable approach to fluorinated heterocycles with potential applications in medicinal chemistry.

Naphthalimide Derivatives as Film‐Based Fluorescent Sensors for Rapid Detection of Illicit Drugs

Advanced Sensor Research, EarlyView.
Four novel 1,8‐naphthalimide (NI) derivatives for the detection of illicit drugs with different substituents at the 4‐position are reported. Their contrasting fluorescence responses enables five illicit drugs to be distinguished from interferents with a mean classification accuracy of 81%.

Ortho-para spin conversion of Ps by paramagnetic O2 dissolved in organic compounds

Nukleonika, 2015
The o-Ps mean lifetime value in liquids decreases in the presence of the paramagnetic oxygen molecules via the ortho-para conversion process. This effect was observed for several organic samples composed of carbon and hydrogen atoms differing in the ...

C(sp3)─S Bond Formation via the Synergy of Oxidative With Reductive Photocatalysts Through Photoredox and Dual Hydrogen Atom Transfer Processes

Advanced Science, EarlyView.
The research reveals that polysulfide anions (K2Sx), which serve as reducing catalysts, can also effectively act as sulfur reagents, providing the formation of C(sp3)─S bonds through photoredox catalysis with an oxidative photocatalyst tetrabutylammonium decatungstate (TBADT) and dual hydrogen atom transfer (DHAT) process.

Physiological pH Transition‐Driven Protein Corona Dynamics Regulate Cellular Uptake and Inflammatory Responses of Silica Nanoparticles

Advanced Science, EarlyView.
Physiological pH transitions modulate protein corona dynamics on nanoparticles, altering their cellular uptake and inflammatory responses. Acidic pHs enhance protein adsorption, induce structural changes, and promote cellular uptake. Simultaneously, inflammatory responses are reduced due to altered protein composition, including decreased ...

Lead Halide Perovskite Nanocrystals in Metal‐Organic Frameworks: Synthesis, Properties, and Applications

Advanced Science, EarlyView.
Perovskites, when applied in devices, face challenges like stability. Integrating halide perovskites into metal‐organic frameworks (MOFs) as composites has gained attention. This approach can enhance stability, facilitate electron transport, and improve crystallinity, thus boosting perovskite performance in various applications.
