Tailoring Amine Substitution in Fluorene and Dibenzothiophene: A Molecular Strategy for Ultralong Organic Phosphorescence

open access: yesAdvanced Optical Materials, Volume 14, Issue 35, 18 September 2026.
Tailored amine substitution in fluorene and dibenzothiophene derivatives enables systematic control of excited‐state properties and triplet population. Combined photophysical studies, TD‐DFT calculations and time‐resolved EPR reveal how charge‐transfer character, sulfur‐induced spin–orbit coupling and triplet manifold engineering cooperate to promote ...

Neurofluid Biomarker Sensors: Integrated Design Strategies From Molecular Recognition to Precision Neurological Diagnosis

open access: yesAdvanced Sensor Research, Volume 5, Issue 9, September 2026.
This review focuses on the principles and signal mechanisms of four types of neurofluid biomarker sensors (electrochemical, optical, mechanical, and multimodal), summarizes the detection strategies for biomarkers such as ions, neurotransmitters, metabolites, and inflammatory proteins and their applications in the diagnosis and treatment of neurological

Real‐Time Stress Visualization of Hydrogels Enabled by Supramolecularly Switched Stretch‐Induced Phase Separation

open access: yesAdvanced Science, Volume 13, Issue 51, 14 September 2026.
Supramolecular hydrogels enable real‐time visualization of mechanical stress through supramolecular switching mechanotransduction. Adamantane‐modified cellulose functions as a responsive domain that undergoes an on–off transition between hydrated and dehydrated states via reversible β‐cyclodextrin–adamantane complexation and decomplexation.

Intrinsic Dual‐Phase Regulated GeSe2 Nanoparticles Triggered by Ball‐Milling Treatment for Photonic Multi‐Valued Logic Circuits

open access: yesAdvanced Science, Volume 13, Issue 53, 24 September 2026.
We report the solid‐state ball milling, a traditional, reliable, mass‐productive material processing, to prepare the air‐stable and dual‐phase GeSe2‐x nanoparticles with extended photodetection feasibility toward optical‐wavelength regions. We further display photonic multi‐valued logic (MVL) circuit through the employment of a hybrid PMMA/GeSe2‐x ...

Near Resonant Raman Optical Activity Study of the Complex Cation Tris(ethylenediamine)cobalt(III) in Water: Experiment and DFT Calculation

open access: yesChirality, Volume 38, Issue 9, September 2026.
Corrected ROA spectrum of the ECD‐Raman (red curve) from the observed raw signal (black curve) reveals the intrinsic ROA signal of Δ‐[Co(en)3]3+, enabling an excellent theory‐experiment agreement. ABSTRACT Chiral metal complexes are important in catalysis and medicinal chemistry, where understanding their structural and optical properties is crucial ...
