Red Multi‐Resonant Thermally Activated Delayed Fluorescence Emitters as Bioimaging Agents

Advanced Optical Materials, EarlyView.
Multi‐resonant thermally activated delayed fluorescence (MR‐TADF) emitters have attracted strong interest for use in electroluminescent devices due to their high photoluminescence quantum yield and narrowband emission. These properties, along with red emission, are also crucial for bioimaging probes.

A Dual‐Emissive DNA‐Templated Silver Nanocluster with Near‐Infrared I and II Emission

Advanced Optical Materials, Volume 13, Issue 8, March 13, 2025.
This study presents a dual‐emissive DNA‐stabilized silver nanocluster with a nanosecond‐lived NIR‐I emission band and a microsecond‐lived NIR‐II emission band. Mass spectrometry establishes that the nanocluster has molecular formula (DNA)2[Ag17]11+. DNA sequence variations reveal critical nucleobases for stabilization, and modifications at the DNA 5 ...

Water‐Mediated 1,7‐Palladium Aryl‐to‐Aryl Migration in an Unusual Aryne Trimerization Enables the Synthesis of Multihelicenes with Profoundly Hindered Stereogenic Axes

Advanced Synthesis &Catalysis, EarlyView.
In the presence of a Pd0 catalyst, large π‐extended arynes trimerize in an unusual manner to forge extremely compact and strained chiral benzenoids. This new trimerization reaction involves a 1,7‐Pd isomerization, a rare and poorly understood process that is elucidated.

Deazaflavin‐Catalyzed Arylation of White Phosphorus with Aryl Bromides and Chlorides

Advanced Synthesis &Catalysis, EarlyView.
The 5‐aryldeazaflavin photocatalyst o‐Me‐dFl catalyzes the arylation of white phosphorus with aryl chlorides and bromides under near UV‐LED irradiation, affording triarylphosphines and tetraarylphosphonium salts. Nuclear magnetic resonance studies and density functional theory calculations offer insights into the reaction pathway.

Iterative Use of Regiocomplementary Flavin‐Dependent Halogenases Gives Access to Unique Halogenation Patterns

Advanced Synthesis &Catalysis, EarlyView.
The halide motif is ubiquitous in organic synthesis, facilitating fine‐tuning of molecular properties and functionalization using substitution and cross‐coupling reactions. Combination of different flavin‐dependent tryptophan halogenases enables the installation of novel halogenation patterns on l‐tryptophan, which can be orthogonally addressed in ...
