Used primarily as an intermediate in the synthesis of advanced organic semiconductors and electroactive materials. It serves as a building block in the preparation of hole-transport materials for organic light-emitting diodes (OLEDs) and perovskite solar cells due to its strong electron-donating properties and thermal stability. Its triphenylamine core with bromo substituents allows for further functionalization via cross-coupling reactions, enabling tailored modification for optoelectronic applications. Also employed in the development of nonlinear optical materials and fluorescent probes, where its extended conjugation and redox behavior enhance performance.
