Description

Some organic solids keep glowing long after the light goes out, and carbazole-based ones were recently traced to trace look-alike impurities rather than the host itself. Zesen Lin and co-authors pin down the mechanism in 2026 by re-examining two host-guest families. Careful spectrum analysis showed the glow is mostly the guest's own phosphorescence, plus a far weaker long-persistent shine.

The guest molecules trap triplet energy deeply and holes shallowly, and the hole trapping feeds the persistent glow. The team folds energy transfer, wandering excitons, and three glow pathways into one framework. Their design rules aim at brighter, longer-lasting afterglow materials made only of organic matter.
