Precisely Regulating 2.45 s Pure Blue Room‐Temperature Phosphorescence via Supramolecular Coordination

Advanced Science, EarlyView.
Herein, a pure deep blue room‐temperature phosphorescence (415 nm) with lifetime up to 2.45 s is successfully achieved by a covalently crosslinking purely organic material based on boric acid (BA) and 3,5‐dicarboxyphenylboronic acid (BOP) through a simple dehydration reaction, which can be adjusted precisely by supramolecular coordination with ...

Galactokinase 1 Positively Regulates Mitochondrial Respiration by Phosphorylating TIMM13 as a Protein Kinase

Advanced Science, EarlyView.
GALK1 acts as a protein kinase beyond the phosphorylation of galactose. GALK1 phosphorylates TIMM13 at Y73 in the cytoplasm. This phosphorylation prevents premature oxidative folding of TIMM13 and ensures its entrance into the intermembrane space of mitochondrion, positively regulating mitochondrial respiration.

Cavity‐Compatible Light Extraction in Top‐Emitting Microcavity OLEDs via a Gentle Internal Corrugation Layer and Resonance‐Matched Narrowband Emission

Advanced Science, EarlyView.
A gentle internal corrugation layer conformally reshapes the microcavity OLED stack, redistributing confined optical power toward extractable channels while preserving cavity‐controlled emission. Combined with optical clear resin and a resonance‐matched narrowband pTSF emissive system, this cavity‐compatible architecture delivers an external quantum ...

Trap‐Programmable Ruddlesden–Popper Perovskite Nanocrystals for Persistent Optoelectronic Memory and Photonic Synapses

Advanced Science, EarlyView.
This work presents trap‐programmable Ruddlesden–Popper perovskite nanocrystals for ultralong‐lived optical memory and photonic synapses. Layer‐controlled octahedral distortion modulates trap depth and carrier‐storage kinetics, enabling persistent luminescence beyond 5000 s at room temperature.

Potassium‐Impurity‐Modulated Self‐Trapped Excitons and Energy Transfer in Phase‐Separated, Mn4+‐Doped Li2HfF6

Advanced Science, EarlyView.
Li2HfF6 contains two spectroscopically distinct self‐trapped excitons (STEs): intrinsic STE1 and redshifted, K‐associated STE2. Potassium incorporation stabilizes STE2, which selectively sensitizes Mn4+ red emission. This work uncovers the often‐overlooked role of trace K impurities, demonstrating impurity modulation as an effective strategy for tuning
