Polymer Dots Exhibiting Multi‐Resonant Thermally Activated Delayed Fluorescence for Cellular Imaging

Advanced Optical Materials, EarlyView.
By copolymerizing with a host material, a multiple resonance thermally activated delayed fluorescent (MR‐TADF) emitter quinolino[3,2,1‐de]acridine‐5,9‐dione (QAO) is successfully assembled into water‐dispersible polymer dots (Pdots). Photophysical measurements and multichannel fluorescence imaging studies show that the narrowband emission from the MR ...

Frequency‐Dependent Demethylation of Cancer DNAs by High‐Power Terahertz Radiation

Advanced Photonics Research, EarlyView.
Effective demethylation of cancer DNA is successfully demonstrated by resonant irradiation with high‐power terahertz (THz) waves at the 10 mW level, combined with metamaterial‐based THz filters. The dependence of spectral filtering on demethylation indicates that the resonant frequency of 1.6 THz of cancer DNAs plays a crucial role in reducing the ...

Direct Access to α,β‐Unsaturated γ‐Lactams via Palladium‐Catalysed Carbonylation of Propargylic Ureas.

Advanced Synthesis &Catalysis, Volume 367, Issue 5, March 4, 2025.
Abstract Additive carbonylations typically necessitate strong nucleophiles, such as alcohols or amines. In this study, we carbonylated a poorly nucleophilic urea, under oxidant‐free conditions. Our straightforward carbonylative strategy enables access to versatile α,β‐unsaturated γ‐lactams featuring an aminocarbonyl fragment, utilizing readily ...

Zero‐Power, Optical Toxic Gas and Vapor Sensors Utilizing Printed Nematic Liquid Crystal Patterns on Selectively Reactive Substrates

Advanced Sensor Research, EarlyView.
Fast response, zero‐power, text or image sensors utilizing light transmission or reflection, and no unfavorable color change judgments, are fabricated using printed nematic liquid crystals patterned on reactive alignment layers, permit ppt‐ to ppb‐level sensitivity, and were field‐tested with active firefighters.
