Used in organic light-emitting diodes (OLEDs) as a key building block for blue emitters due to its strong electron-transport properties and high thermal stability. Commonly employed in the development of host materials for phosphorescent OLEDs, where it helps improve device efficiency and lifetime. Also utilized in perovskite solar cells as a dopant or interfacial layer to enhance charge transport and reduce recombination. Its bromine functionality allows for easy modification via cross-coupling reactions, making it valuable in synthesizing more complex organic semiconductors. Found in research settings for fabricating organic field-effect transistors (OFETs) and other optoelectronic devices.
