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

open access: yesAdvanced 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

open access: yesAdvanced 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

open access: yesAdvanced 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.

Mg(SPh)2 as a Catalyst for Efficient Photocatalytic Alkylation Reactions of Active Methylene Compounds with Nonactivated Alkenes

open access: yesAdvanced Synthesis &Catalysis, Volume 367, Issue 5, March 4, 2025.
Abstract Mg(SPh)2 has been found to be a highly active catalyst in photocatalytic alkylation reactions of active methylene compounds with nonactivated alkenes. The desired reactions proceeded smoothly to afford the corresponding alkylated products in high yields with low catalyst loadings (0.2–0.3 mol%). This protocol is applicable to a continuous‐flow
