Two carbazole‐benzimidazole derivers with high bandgap were developed. Employing as host of organic light emitting diodes (OLEDs), the high efficiency blue phosphorescence (with FIrpic emitter), blue thermally activated delayed fluorescence (TADF) (with our TO‐DPS emitter), and green TADF (with 4CzIPN emitter) OLEDs were achieved over 30% in external quantum efficiency.
