Abstract Achieving predictable color-tunable organic room-temperature phosphorescence (RTP) remains challenging due to limited understanding of triplet-state regulation in heteroaromatic systems. Carbazole and benzindole isomers provide an ideal platform to clarify how nitrogen positional isomerism governs triplet exciton behavior and emission energetics. Here, we establish a unified comparative framework to systematically investigate carbazole together with Bd[f], Bd[e], and Bd[g].
