Used as an intermediate in the synthesis of organic semiconductors and optoelectronic materials. Its bromoethyl and chloro-substituted structure allows for further functionalization in cross-coupling reactions, making it valuable in the development of hole-transport materials for OLEDs and perovskite solar cells. Also employed in the preparation of conjugated polymers and small molecules for use in organic field-effect transistors (OFETs). The compound’s rigid carbazole core enhances thermal stability and charge transport properties in resulting materials.
