Site Density Governs Switching Reactivity Regimes During Aerobic C─H Oxidation in Mn Single‐Atom Photocatalysts

Angewandte Chemie, EarlyView.
Increasing the density of isolated manganese (Mn) atoms in carbon nitride (CNx) photocatalysts does not continuously improve performance. Instead, beyond a critical loading, the polymer support reorganizes, altering charge‐carrier dynamics and oxygen activation while preserving atomic dispersion.

Pt‐Mediated Co‐Adsorption of Hydroxyl and Nitrogen‐Heterocyclic Species Over Cu/CuO Heterostructure Enhances Coupled Azotriazole Electrosynthesis and Dual‐Electrode Hydrogen Production

Angewandte Chemie, EarlyView.
Pt@Cu/CuO heterostructures were designed for electrochemical N─N coupling of 3,5‐diamino‐1H‐1,2,4‐triazole. Mechanism investigation revealed that the Pt sites mediated co‐adsorption of substrates and hydroxyl on Cu/CuO sites. The elaborate Pt@Cu/CuO achieved an ultralow working potential of 0.832 VRHE with a high FE of 95%. A long‐term stability of 600

Anion–π Interaction‐Regulated Ion Generation and High Piezoionic Response in Ultrasoft Low‐Salinity Hydrogels

Angewandte Chemie, EarlyView.
The first hydrogel system employing anion–π interactions as a central design motif is developed. The cooperative aromatic–phosphate interaction motif provides dynamic cohesion and is proposed to regulate the separation and transport of water‐derived ionic species, achieving high piezoionic response in injectable, self‐healing, ultrasoft, low‐salinity ...

Syntheses, X‐ray Crystal Structures, and Raman Spectra of Self‐Assembled XeO3 Chain and Network Complexes of Polytopic sp2‐ and sp3‐Nitrogen Bases

Angewandte Chemie, EarlyView.
Supramolecular 1‐D, 2‐D, and 3‐D networks comprised of ‐(‐O═Xe(O2)‐‐)‐∞ and ‐(‐Xe(O2)O‐‐‐HO(H)‐‐)‐∞ chains coordinated to polytopic N‐base ligands were synthesized and structurally characterized by X‐ray crystallography. Their Xe‐‐‐N and Xe‐‐‐O bonds are characteristic of σ–hole bonds in which the nucleophilic Lewis base sites of the N‐ligands, H2O ...

TADF‐Active Tetrazole Luminophores for Visible‐Light Functionalization of Nanoparticles and Surfaces

Angewandte Chemie, EarlyView.
A series of tetrazoles are reported that undergo 1,3‐dipolar cycloadditions with alkene and alkyne substrates, generating (dihydro)pyrazole products that exhibit thermally activated delayed fluorescence (TADF). The “photo‐click” reactivity of these tetrazoles is leveraged to functionalize nanoparticles and surfaces with TADF‐active chromophores ...
