Spiro‑Linked Double Tetraphenylethenes: Solid‐State Emission and Circularly Polarized Luminescence Imaging

Angewandte Chemie, EarlyView.
Two spirobisanthracene‐tetraphenylethene (SBA‐TPE) hybrid compounds are synthesized and their photophysical properties in the solid state reported. Circularly polarized luminescence in aggregates, films and dispersions is evaluated. Circularly polarized luminescence imaging is evaluated over crystals revealing discrimination of different types of ...

Inhibitory Decay and Supercritical Brain Dynamics During Sleep Deprivation

Advanced Science, EarlyView.
Sleep deprivation progressively shifts human brain dynamics from near‐critical toward supercritical states, as revealed by neuronal avalanche analysis of resting‐state fMRI. These changes track subjective sleep pressure rather than vigilance lapses and show marked network heterogeneity. A circuit model suggests that reduced inhibitory efficacy provides

Quantum Photothermal Self‐Monitoring Fiber Probes for In Vivo Photothermal Therapy

Advanced Science, EarlyView.
A miniaturized quantum photothermal fiber probe based on a metal/polymer/glass composite optoelectronic fiber that simultaneously guides lightwave and microwave was developed for the first time. The probe achieves enhanced photothermal conversion (13°C/mW, 25°C–120°C range) while providing real‐time self‐monitoring with 0.2°C thermal resolution at the ...
