Water‐Enabled Ultralong Full‐Color Organic Phosphorescence in Hydrogen‐Bonded Frameworks for 4D Encryption and Bio‐Imaging

Advanced Science, EarlyView.
Water‐induced quenching challenges organic RTP materials, but a counter‐intuitive strategy employs HOF to encapsulate carbonyl guests, where water functions as a structural reinforcer. This achieves water‐enhanced ultralong RTP with full‐color emission (blue to deep red), overcoming intracellular quenching for high‐signal cellular imaging, alongside 4D

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

Advanced Science, EarlyView.
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.

Polymer‐Based Multiparameter Sensing Integrated Photonic Chip for Health Monitoring

Advanced Science, EarlyView.
A monolithic integrated photonic chip simultaneously measures blood glucose, pressure, temperature, ECG, and sweat glucose. Combining multiple Bragg grating sensors, Mach–Zehnder modulators, and an on–‐chip demodulation unit, this compact chip (1 cm × 0.5 cm) offers robust multiparameter detection.

Donor Extended Blue TADF Dendrimer for High‐Performance Solution‐Processed OLEDs

Advanced Science, EarlyView.
A dendronized MR‐TADF emitter, DOBNA‐SpAc‐DCz, was designed to improve solubility, hole transport, and exciton dynamics for solution‐processed OLEDs. Incorporation of ter(tert‐butylcarbazole) dendrons decreases ΔEST and accelerates RISC, yielding short delayed lifetimes (∼2 µs).

Bypassing Pre‐Photoactivation in High‐Barrier Polyamide for Robust and Scalable Organic Persistent Luminescence

Advanced Science, EarlyView.
A universal paradigm resolves the trade‐off between ambient stability and barrier properties in organic persistent luminescent (OPL) polymers. By interlocking chromophores within a high‐barrier MXD6 matrix, we achieved no Pre‐photoactivation OPLs with exceptional long‐term stability in water.

Carboxylate‐Driven Metal Pre‑Fixation COF@MOF Synthesis: Enabling Tailored Structural, Dimensional, and Defect Engineering

Advanced Science, EarlyView.
A universal metal pre‐fixation (MPF) strategy directs the precise crystallization of diverse metal‐organic frameworks (Co‐MOF, ZIF‐8, Fe‐MOF, UIO‐66) on covalent organic framework (PY‐COF) scaffolds. The resulting hierarchical hybrids exhibit tunable porosity, structural defective and dimensional, as well as enhanced performance in CH4/C2H6/C3H8 ...
