Popis: Abstract In this study, a multiple‐resonance (MR) core structure is developed with a spin‐flip‐restricted emission mechanism based on a fused indolo[3,2,1‐jk]carbazole (ICz) framework as emitters to improve the lifetime of blue organic light‐emitting diodes. The molecular skeleton modulation approach applied to the conjugated π‐system effectively stabilizes the triplet energy of the fused ICz emitters and narrows the full‐width‐at‐half maximum (
