Metal‐Mediated Nitrogen Doping of Carbon Supports Boosts Hydrogen Production from Ammonia

Angewandte Chemie, EarlyView.
A virtuous catalytic cycle is established as the carbon support simultaneously tunes electron density and stores atomic nitrogen formed via Ru–N species during ammonia decomposition, resulting in self‐enhancing catalysis. Abstract Ammonia is an attractive hydrogen carrier, yet its practical use is limited by the need for efficient catalytic ...

Non‐Statistical Assembly of Donor–Acceptor Cages for Light‐Induced Charge Separation

Angewandte Chemie, EarlyView.
Donor–acceptor functionalized cages [Pd2D2A2]4+ with defined stoichiometry and stereoconfiguration were assembled in a single step by employing the shape complementary assembly (SCA) strategy. While the redox functionalities remain largely independent in the ground state, photoexcitation results in ultrafast ligand‐to‐ligand charge transfer, as ...

Benzoyl‐Xanthenoxanthenes: Versatile Chromophores for Light‐Engaging Applications

Angewandte Chemie, EarlyView.
Oxidatively stable benzoyl‐fused peri‐xanthenoxanthene ribbons with NIR emission were synthesized. Their good spectral overlap enabled cascaded Förster resonance energy transfer (FRET) antennae in a nematic liquid crystal phase, achieving directional energy transfer.

Dual Chemical Looping/Catalytic Process for Alkylation of Benzene With Ethane and Propane Yielding Ethylbenzene and Cumene Over Copper‐Containing Mordenite

Angewandte Chemie, EarlyView.
We report a dual chemical looping/catalytic process coupling alkane dehydrogenation with aromatic alkylation over Cu‐mordenite, yielding up to 25% alkylated aromatics with >95% selectivity per cycle. In situ NMR, FTIR spectroscopy, and DFT show alkylation proceeds via a π‐bound Cu(I)–olefin intermediate and Brønsted acid sites.
