Dispersion‐Enhanced Nitrogen‐Centered Photocatalysis of the Direct Hydrogen Atom Transfer

open access: yesAngewandte Chemie, EarlyView.
Nitrogen‐centered acridine photocatalysts for direct hydrogen atom transfer have been developed, leveraging dispersion interactions to enhance photocatalytic activity. This approach enables diverse functionalization reactions of strong C─H bonds even under cryogenic conditions and provides a new strategy for boosting the efficiency of direct HAT ...

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

open access: yesAngewandte 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

open access: yesAngewandte 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 ...

Molecular Cages as Probes in Indicator Displacement Assays: The Case of Scopolamine Detection

open access: yesAngewandte Chemie, EarlyView.
In this research, we show the concept of molecular cages as probes in indicator displacement assays, focusing on scopolamine detection, a drug often used in drug‐facilitated sexual assaults. Drug sensing occurs via the drug‐induced transformation of non‐emissive [Fluorescein2⊂Cage] complex into [Scopolamine⊂Catenane] and highly emissive free ...
