Description

1,3,5-Tris[4-[bis(4-methoxyphenyl)amino]phenyl]benzene (CAS No. 142894-38-0) is a high-purity, triphenylamine-based organic compound with the molecular formula C₆₆H₅₇N₃O₆. This advanced material features a star-shaped molecular architecture with three bis(4-methoxyphenyl)amino functional groups symmetrically arranged around a central benzene core, making it an excellent hole-transport material (HTM) for optoelectronic applications. With exceptional thermal stability and excellent charge-carrier mobility, this compound is particularly valuable in organic light-emitting diodes (OLEDs), perovskite solar cells (PSCs), and other organic electronic devices. Its extended π-conjugation and electron-rich methoxy-substituted triphenylamine moieties contribute to superior hole injection and transport properties. Available in >98% purity (HPLC), this compound is rigorously tested for consistency and performance in research and industrial applications.
