Used as a key intermediate in organic semiconductor materials, particularly in the development of hole-transport layers for OLEDs (organic light-emitting diodes). Its extended aromatic structure and amine functional groups enhance charge carrier mobility, making it suitable for use in display technologies and flexible electronics. Also employed in the synthesis of conjugated polymers for photovoltaic cells due to its ability to stabilize positive charges and support efficient electron delocalization. Additionally, serves as a building block in the preparation of high-performance fluorescent dyes and sensors, where its triphenylamine core contributes to strong emission properties and thermal stability.
