Used as an intermediate in organic synthesis, particularly in the preparation of functional materials for optoelectronic devices. It serves as a building block in the development of organic light-emitting diodes (OLEDs) and organic photovoltaics (OPVs) due to its ability to support charge transport and enhance material stability. The presence of bromo and chloro substituents allows for further functionalization via cross-coupling reactions, enabling the construction of complex conjugated systems. Its rigid fluorene backbone with diphenyl groups contributes to high thermal stability and favorable film-forming properties, making it suitable for use in thin-film semiconductor applications.
