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

open access: yesAdvanced 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

Non‐Equilibrium Synthesis of Whitlockite Assisted by Localized H2O Vapor Pressure

open access: yesAdvanced Science, EarlyView.
A carbon substrate acts as a microheater during intense pulsed light irradiation, enabling rapid heating and cooling for whitlockite formation. In contrast to conventional white ceramic synthesis with weak photothermal response, this platform concentrates thermal energy locally and promotes phase‐selective crystallization under ultrafast ...
