Machine Learning–Enhanced Fluorescence Cryptography with NADH‐Responsive Polymer Dots

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This study presents a smart anticounterfeiting system using semiconducting polymer dots (Pdots) that exhibit tunable fluorescence responses to NADH. By integrating these dynamic optical signals with machine learning–based decoding, the work establishes a secure and intelligent encryption platform, showing a novel strategy that links chemical sensing ...

Phototriggered Morphological and Compositional Change of UGGAA Repeat RNA Foci by Photoswitchable RNA‐Binding Ligand

open access: yesAngewandte Chemie, Volume 138, Issue 18, 27 April 2026.
We here developed a molecular tool for the optical control of UGGAA repeat RNA foci, a pathological hallmark of spinocerebellar ataxia type 31 (SCA31). The photoswitchable RNA‐binding ligand enabled reversible control of the RNA foci. UV irradiation induced the growth of the RNA foci, while subsequent visible light irradiation dissolved the structure ...

Diverse reactivity of maleimides in polymer science and beyond

open access: yesPolymer International, Volume 74, Issue 4, Page 296-306, April 2025.
This mini‐review provides a thorough overview of maleimide chemistry, highlighting its diverse reactivity in polymer and materials science applications. Abstract Maleimides are remarkably versatile functional groups, capable of participating in homo‐ and copolymerizations, Diels–Alder and (photo)cycloadditions, Michael additions, and other reactions ...

Oxygen‐Acceptor‐Driven High Photochromic Contrast Solid‐State Excited‐State Intramolecular Proton Transfer Photoswitches

open access: yesAngewandte Chemie, Volume 138, Issue 18, 27 April 2026.
The excited‐state intramolecular proton transfer (ESIPT) photoswitch tpmSA, which features an oxygen−acceptor, exhibits higher photochromic contrast (ΔE*Lab>74) than its nitrogen‐acceptor Schiff base analogues (ΔE*Lab<30). Theoretical calculations indicate that tpmSA effectively suppresses GSIPT, thereby enhancing the contrast.
