Orchestrating Anion–π+ Interactions to Accelerate Metal‐Free Room‐Temperature Phosphorescence

Angewandte Chemie, EarlyView.
Tuning anion–π+ interactions in pyridinium iodide contact ion pairs enables ultrafast metal‐free room‐temperature phosphorescence (540–605 nm) with radiative rates up to 5.2×105 s−1. Strong iodide→π+ charge‐transfer coupling, enhanced spin–orbit interactions, and dynamic ion‐pair organization accelerate intersystem crossing and emission, establishing ...

Heat‐ and Light‐Directed Cycloadditions Enable a Pericyclic Cascade Reaction From a Molecular Precursor

Angewandte Chemie, EarlyView.
A multi‐stimuli‐responsive material is designed that responds to light, heat, and mechanical force through distinct chemical reaction pathways. The pathway is directed by self‐assembly and the applied stimulus. A novel pericyclic reaction cascade is also achieved, and the mechanism is supported through density functional theory calculations.

Photoswitchable Ambiphilicity: Light‐Gated Frustrated Lewis Pair Reactivity and Z‐Type Interaction

Angewandte Chemie, EarlyView.
Light‐controlled ambiphilicity is realized in photoswitchable intramolecular phosphorus/boron Lewis pairs. Reversible switching modulates both the thermodynamics and kinetics of frustrated Lewis‐pair reactivity, enabling light‐gated CO2 binding and release.

Synergistic Silylium‐Ion and Palladium Catalysis Enables Migratory Alkene Silylation With Allylsilanes by Formal C–H/C–Si Metathesis

Angewandte Chemie, EarlyView.
Merging silylium‐ion and palladium catalysis provides a mechanistically distinct route to allylsilanes by formal C–H/Si–H metathesis. Using allylsilanes as silicon proelectrophiles, various allylarenes undergo migrative silylation, selectively yielding (E)‐allylsilanes.

Bistabiles Schalten der π‐Konjugation in einem Dithienylethen‐verbrückten lumineszierenden Trityl‐Diradicaloid

Angewandte Chemie, EarlyView.
Photoschalter, die die π‐Konjugation beeinflussen, bieten eine wirkungsvolle Strategie für die externe Manipulation von lumineszierenden Diradikalen. Dithienylethen‐verbrückte persistente Trityl‐diradikaloide, DTE‐TTM2 und F6‐DTE‐TTM2, zeigen ein bistabiles Schalten ihrer optischen, elektrochemischen und magnetischen Eigenschaften.
