—— Product Detail ——

Product Overview

N,N'-Diphenyl-N,N'-di-m-tolylbenzidine (CAS 65181-78-4) is a triphenylamine derivative with the molecular formula C₃₈H₃₂N₂ and a molecular weight of 516.67 g/mol. The compound features a benzidine core with phenyl and m-tolyl substituents on the nitrogen atoms. This compound is a high-performance hole-transporting material widely used in organic light-emitting diode (OLED) devices and organic photovoltaics.

Synthetic Process

The synthesis typically involves the palladium-catalyzed Buchwald-Hartwig amination of 4,4'-dibromobiphenyl with diphenylamine and di-m-tolylamine, or the stepwise coupling of appropriate amine precursors.

Mechanism of Action

The compound exhibits excellent hole-transporting properties due to the electron-rich nitrogen atoms and the extended π-conjugation of the aromatic system. It is widely used as a hole-transport layer in OLED devices.
