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

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.

Conformational Transduction Amplification in a Biomimetic Polyelectrolyte for Ultrasensitive Imaging of Iron Metabolism

Advanced Science, EarlyView.
This work designs a peptide‐free polyelectrolyte with stable, switchable conformations and near‐infrared fluorescence in water. It harnesses a cooperative Fe3+‐triggered sheet‐to‐helix transition to generate nonlinear fluorescence quenching, enabling the ultrasensitive, real‐time visualization of Fe3+ ion distribution and metabolic trafficking at ...

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 ...
