Bridging Stability and Reactivity: Novel Dinucleating Ligand With Rigid Backbone Stabilizes a Cu2O2 Side‐On Peroxido Structure

European Journal of Inorganic Chemistry, EarlyView.
The herein‐developed tyrosinase model complex enables the transfer of tyrosinase‐like catalytic oxygenation activity into artificial systems. Therefore, it enables the use of molecular oxygen for oxygenation and oxidation of phenolic substrates at room temperature.

Visible Light or Brønsted Acid Promoted Oxygenation of a PdBn(NNP(O)) Complex

European Journal of Organic Chemistry, EarlyView.
A benzylpalladium complex with a tridentate NNP ligand containing 2,2′‐bipyridine and a phosphoryl moiety [PdBn(MeNNP(O))] reacted readily with O2 to afford an O2‐inserted complex. The insertion was accelerated using ambient light. By contrast, the reaction with O2 under blue LED irradiation afforded PhCHO as the major oxygenated product.

Properties of [Fe(salen)]2‐μ‐Oxo Derivatives and Their Effect on Catalytic Hydrophosphination

European Journal of Organic Chemistry, EarlyView.
A series of [Fe(salen)]2‐μ‐oxo and [Fe(salophen)]2‐μ‐oxo complexes were synthesized to probe how ligand electronics and backbone rigidity influence redox behavior and catalytic hydrophosphination of styrene. Electron‐withdrawing substituents enhance stability and activity, enabling tunable, efficient C–P bond formation.

Exercise‐specific plasma proteomic signatures in racehorses: Candidates for training adaptation and peak load monitoring

Equine Veterinary Journal, EarlyView.
Abstract Background Racehorses undergo profound physiological changes with training and competition, but current biomarkers inadequately capture the complex molecular dynamics of exercise. This study aimed to identify novel plasma biomarkers of training adaptation and peak load using high‐throughput proteomics.

Synthesis of Tris(Dimethylamino)Phosphine‐Based InP Quantum Dots and Their Application in Light‐Emitting Diodes: Progress and Perspectives

Exploration, EarlyView.
A lot of subtle but key tricks in the synthesis of (DMA)3P‐based InP QDs and device mechanisms were not explicitly explained in the published works. This review firstly provides a comprehensive analysis of the molecular structures and distinct reaction mechanisms of (TMS)3P and (DMA)3P during InP core nucleation.

Heteroatom location‐ and orientation mode‐dependent reverse intersystem crossing rate in multiple resonance emitters

FlexMat, EarlyView.
By constructing two pairs of isomers with different heteroatom anchoring positions, the relationship between heteroatom location and orientation mode and reverse intersystem crossing rate constant (kRISC) in multiple resonance (MR) emitters is systematically investigated.
