N,N′-Bis(4-methylphenyl)-N,N′-diphenylbenzidine (p-TPD)(CAT: M440001) is a widely used hole-transport material in organic optoelectronic devices. With a robust triphenylamine-based structure, p-TPD offers excellent hole mobility, high thermal stability, and efficient energy-level alignment with common electrode materials. It is frequently employed in organic light-emitting diodes (OLEDs), organic photovoltaics (OPVs), and perovskite solar cells, where it enhances charge injection, improves device efficiency, and extends operational lifetime. Its good film-forming properties and compatibility with multilayer device architectures make it a standard material in thin-film electronics. Combining stability, performance, and versatility, p-TPD remains a benchmark hole-transport compound in next-generation optoelectronic applications.
