Thermally Activated Delayed Fluorescence Chiral Molecules Exhibiting Photoinduced Radical Emission

Key Points

• The aim is to achieve room-temperature stable, photoinduced radical emission in chiral TADF molecules.
• Utilized chiral D-A-D′ TADF molecules doped in PMMA (poly(methyl methacrylate)) for study.
• Investigated host-guest interactions to suppress non-radiative decay effects.
• Analyzed the radical emission behavior under various conditions.
• Achieved stable photoinduced radical emission at room temperature.
• Enhanced TADF due to host-guest interactions reducing non-radiative decay.
• Demonstrated reversible radical emission through an anti-Kasha mechanism.
