Hydrogen Atom Transfer Induces Photodegradation in Carbonyl‐Based Multi‐Resonance TADF Emitters

Angewandte Chemie, EarlyView.
Boosting triplet harvesting in N/C═O MR‐TADF emitters unexpectedly induces rapid photodegradation under oxygen‐free conditions. Spectroscopic studies reveal that triplet excited states trigger hydrogen‐atom transfer from solvent to the carbonyl unit, driven by triplet energetics and hydrogen electrophilicity.

Steric Hindrance and Secondary Interactions Govern Reconfiguration Between Two Complex CuI Coordination Cages

Angewandte Chemie, EarlyView.
Fine‐tuning steric and C─H···π contacts directs assembly of two CuI cages. An identical naphthylene‐based subcomponent forms a [CuI12L6]12+ pseudo‐hexagonal prism stabilized by 29–32 C─H···π contacts and 12 arene stacking pairs with 6‐methyl‐2‐formylpyridine, whereas the 3‐methyl analog imparts steric clashes, yielding a [CuI8L4]8+ open prism ...

Stimuli‐Responsive Silsesquioxane Nanozymes for Organocatalysis in Water and Prodrug Activation in Cells

Angewandte Chemie, EarlyView.
Amino‐bearing silsesquioxanes are water‐stable nanozymes that exhibit aggregation‐ and disaggregation‐dependent catalysis and can be applied to intracellular prodrug activation for cancer therapy. ABSTRACT Synthetic nanozymes have emerged as promising alternatives to natural enzymes for catalytic and therapeutic applications, yet their limited ...

Oxidation State Determines Solvent Structure Around a Manganese–Vanadium Polyoxometalate Water‐Oxidation Catalyst

Angewandte Chemie, EarlyView.
Oxidation state controls microsolvation in the polyoxometalate {MnV}n−$\{{\rm MnV}\}^{n-}$ water‐oxidation catalyst in acetonitrile/water mixtures. The reduced species {MnV}3− attracts a highly structured hydration layer even at low water content, preferentially binding terminal V═O sites and excluding acetonitrile, while oxidized species show weaker ...
