A series of deep-blue solution-processable imidazole derivatives, BuCzI and BuCzI-PCN, were synthesized by employing 3,6-di-tert-butyl-carbazole at N1 position of imidazole. The solution-processed undoped OLEDs were fabricated with BuCzI and BuCzI-PCN as emitter achieved EQE of 3.38% and 2.75% with CIE of (0.15, 0.05) and (015, 0.11), respectively.
