Enhanced Electron‐Capturing by Single‐Atomic Iron on Pyridinic N‐Deficient Carbon Drives Self‐Oxidative Degradation of Pollutants

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Pyrolysis of FeOx/g‐C3N4 and ZIF‐8 is performed to introduce Fe single atom and pyridinic nitrogen vacancies onto N‐doped carbon. This modification enables the materials to efficiently extract electrons from ciprofloxacin (CIP) and activate dissolved oxygen. 100% of CIP was degraded within 1 min without adding any oxidant.

Main Group Metals in Redox Catalysis

European Journal of Inorganic Chemistry, EarlyView.
Main group metal redox catalysis is emerging as a credible alternative to transition metal chemistry. Elements from groups 13 to 15 now enable diverse catalytic manifolds, driven by ligand design and control of electronic structure. This review highlights recent advances, key design principles, and remaining challenges, positioning main group metals as

Design, Synthesis, and Photophysical Studies of Functionalized Polyaromatic Isonitriles as Visible Light Photoredox Catalysts

European Journal of Organic Chemistry, EarlyView.
A new series of structurally rich polyaromatic isonitriles is presented as photoredox catalysts. Their photophysical properties are investigated by UV–Vis absorption and fluorescence measurements, combined with experimental and theoretical studies to evaluate both ground‐ and excited‐state redox properties.

Mechanistic and Reactivity Insights into Diboron‐Mediated NN and NN Bond Scission

European Journal of Organic Chemistry, EarlyView.
This review highlights the emerging ability of diboron reagents to cleave both π‐bonded (N=N) and σ‐bonded (N—N) nitrogen–nitrogen linkages, integrating mechanistic understanding with recent synthetic applications. Diboron reagents have emerged as versatile reducing agents capable of transforming a broad range of functional groups through pathways like

Synthesis of Benzopyran Atropisomers via Electrophilic Halogenation

European Journal of Organic Chemistry, EarlyView.
We report a halogenation‐based method for the synthesis of axially chiral benzopyrans, tolerating diverse substituents and halogens (Br, Cl, and I). A double bromination gives bisbenzopyrans with two stereogenic axes. Preliminary enantioselective conditions yield benzopyran atropisomer with up to 56% ee.

Sustained‐Release Ulcer‐Protective Microarray Patch With Dihydrocapsaicin for Diabetic Wound Regeneration

Exploration, EarlyView.
Schematic illustration of the effect of microneedles incorporating cerium‐based MOF loading dihydrocapsaicin (MN‐MOF@DHC) to scavenge reactive oxygen species (ROS) generation, beanti‐inflammatory, inhibit the apoptosis of endothelial cells (ECs), promote angiogenesis, and accelerate diabetic wound healing. ABSTRACT Diabetic foot ulcers (DFUs) present a
