A convenient intermediate for construction of more complex structures

Used in application of organic photovoltaic and OLED devices.


2-Bromo-9H-carbazole is a mono-brominated derivative of 9H-carbazole at 2-position bearing both bromo and amine functional groups. It has been used for further synthesis of semiconducting small molecules and polymers in application of OLEDs, dye sensitized solar cells, polymer and perovskite solar cells.

PyEtCz, a deep blue fluorescent material derived from 2-Bromo-9H-carbazole, shows good thermal stability exhibits strong deep-blue emission with high fluorescent quantum yield of 75%. Device performance with maximum luminance of 6573 cd m-2 and maximum luminance efficiency of 3.24 cd A-1 (3.35%) was achieved with CIE coordinate of (0.15, 0.10). The molar ratio of the 2-bromo-9H-carbazole phosphor to acrylamide can strongly influences the room-temperature phosphorescent (RTP) emission intensities and quantum yields of the blue–purple phosphorescence emitting amorphous copolymer of 2-bromocarbazole phosphor and acrylamide [1, 2].
