Used as a key intermediate in the synthesis of organic semiconductors, particularly in the development of high-performance materials for organic light-emitting diodes (OLEDs) and organic field-effect transistors (OFETs). Its bulky didodecyl side chains enhance solubility in organic solvents, facilitating solution-based processing techniques like spin coating and inkjet printing. The fluorene core with amine functional groups at 2 and 7 positions provides excellent charge transport properties and stability, making it valuable in optoelectronic devices. Commonly employed in donor materials for organic photovoltaics (OPVs) due to its ability to form stable radical cations and support hole transport.
