Imidazole derivatives for efficient organic light-emitting diodes

Journal of Information Display, 2020
Since the first development of organic light-emitting diodes (OLEDs) in 1987, imidazole derivatives, mainly including phenanthroimidazole (PI) and benzimidazole (BI), have increasingly attracted attention.
