N1,N1'-(biphenyl-4,4'-diyl)bis(N1-phenyl-N4,N4-di-m-tolylbenzene-1,4-diamine) Usage And Synthesis

Description

Bearing four triarylamine units, DNTPD is electron rich and normally used as hole transport or hole injection layer material in OLED and perovskite solar cell devices. It is an extended structure of TPD?and NPB that is widely used in organic electronics.

Uses

DNTPD can be coated on indium tin oxide (ITO) to form an optimized device with an electron transporting layer for the fabrication of high efficiency organic light emitting diodes (OLEDs).

General Description

DNTPD is a hole transporting material with good optical properties. It has high ionization energy (IE) and hole mobility which allow excellent performance for electron blocking.
