d‐Orbital Electron Spin Polarization Field Inhibits Photo‐Generated Carrier Recombination for Panel Photoelectrocatalysis

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A solution‐processable sub‐nanocrystal of metal coordinated conjugated reticular oligomer with spin polarization functionality is employed as an active layer in planar photoelectrochemical water splitting. The rapid recombination of photo‐generated carriers remains a critical challenge limiting the photo‐electrocatalytic water splitting performance in ...

Fluorescence Behavior of Water‐Soluble Porphyrins Immobilized on LTA Zeolite and Its Chlorogenic Acid Polyphenol Sensing in Coffee Wastewater

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
During coffee bean and cherry washing, contaminants are released into water, making this process a major source of water pollution. Chlorogenic acid can be efficiently detected using hybrid zeolite–porphyrin materials by measuring fluorescence quenching, achieving detection limits lower than current regulatory thresholds.

Metal‐Free Ligand‐Centered Radical Scavenging in Pyridine‐Modified Tetraaza Macrocycles

European Journal of Organic Chemistry, EarlyView.
Ligand‐centered hydrogen‐atom transfer in pyridinophane macrocycles generates delocalized radicals, with Py2N2 enabling cooperative captodative stabilization and enhanced DPPH• quenching. Pyridine‐modified tetraaza macrocycles are widely studied as ligand platforms for metal coordination, yet their intrinsic redox and radical reactivity in the absence ...

Retro‐Hetero‐Michael Addition Strategies in Organic Synthesis

European Journal of Organic Chemistry, EarlyView.
In this review, synthetic approaches to carbo‐ and heterocyclic compounds, including natural products, published in the last 15 years (2011–2025) which have either relied upon or included a retro‐hetero‐Michael addition step at any stage are discussed.

Infrared Irradiation‐Assisted Pd/Cu Catalysis for Sustainable C–N Cross‐Coupling Reactions

European Journal of Organic Chemistry, EarlyView.
A combined Pd/Cu catalytic system is demonstrated to be highly effective in promoting infrared irradiation‐assisted Buchwald–Hartwig aminations under nonanhydrous and open‐air conditions, using only a stoichiometric amount of a green reaction solvent.
