Description
Xiang-Chun Li and co-authors present a 2026 study on making porous crystals glow with recycled light. Covalent organic frameworks are precise, tunable lattices. In devices they waste three quarters of their excited states as dark triplets. A trick called thermally activated delayed fluorescence can harvest those triplets, but it needs floppy molecules, while crystals demand stiffness.
The team resolved the clash by locking donor-acceptor pairs inside the framework's nanopores. Confinement forced the pairs into shapes with a tiny energy gap between states. The stiff lattice also muffled the vibrations that waste energy. Free-standing films glowed brightly, and solution-made OLEDs performed well for porous emitters. The method turns the framework from a passive shelf into an active light manager.
