A new donor moiety, 7,7,13,13‐tetramethyl‐7,13‐dihydro‐5 H ‐indeno[1,2‐ b ]acridine (IAc), was developed to control the highest occupied molecular orbital (HOMO) dispersion of thermally activated delayed fluorescent (TADF) emitters. The IAc unit expanded the HOMO dispersion of the emitters and increased the quantum efficiency of the TADF devices up to 20.9 %.
