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 ...

Microlasers Made Entirely from Edible Substances

Advanced Optical Materials, EarlyView.
Several types of microlasers made completely out of edible substances are developed. They can be embedded directly into edible products and enable the sensing of various parameters, including sugar concentration, pH, the presence of bacteria, and exposure to too‐high temperatures.

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.
