Solid-state light-emitting electrochemical cells (LECs) using sustainable and eco-friendly materials and affording high brightness, efficiency, and stability are highly desired. Here, intrinsically ionic, thermally activated delayed fluorescence (TADF) materials 1–3 for efficient, bright, and stable LECs are reported. 1–3 feature carbazole-type donors and cationic triazine-type acceptors, which are located ortho to each other on the phenyl linkers. Through-space charge-transfer (CT) dominates the CT transitions in 1–3. In doped and neat film...
