Revealing Mechanofluorochromism and Intricate Long‐lived Decay Pathways in Keto‐Coumarin‐Based Molecular Crystals

Advanced Optical Materials, Volume 14, Issue 35, 18 September 2026.
Donor–acceptor organic emissive materials show great promise in cutting‐edge optical applications. Herein, the photophysical properties of two keto‐coumarin organic materials are studied in detail. Both show mechanofluorochromism, but a diphenylamine donor derivative exhibits intricate decay pathways in the crystal form, including decays ranging from ...

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

Advanced Science, Volume 13, Issue 50, 7 September 2026.
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

Color‐Tunable Organic Room‐Temperature Phosphorescence From Single‐Luminophore Aggregation in Polymer

Aggregate, Volume 7, Issue 9, September 2026.
A single‐luminophore design featuring a planar π‐conjugated carbazole core and sterically hindered side groups affords a distinctly low critical aggregation concentration. Concentration‐controlled evolution from monomers to π–π stacked dimers enables continuous room‐temperature phosphorescence color tuning from green to orange–red with lifetimes ...
