Used in organic semiconductor materials due to its electron-transport properties, particularly in the development of organic light-emitting diodes (OLEDs). Serves as a building block in the synthesis of conjugated polymers and small molecules for optoelectronic devices. Its bromine functionality allows for further modification via cross-coupling reactions, making it valuable in creating complex aromatic structures for advanced materials research. Also explored in the design of host materials for phosphorescent OLEDs owing to its thermal stability and suitable energy levels.
