Room-temperature stable, photoinduced radical emission is achieved in chiral D-A-D′ TADF molecules doped in PMMA. Hostguest interactions suppress non-radiative decay, enhancing TADF and enabling reversible radical emission via an anti-Kasha process from higher excited states (D2/D3). This offers new strategies for photoresponsive materials.
