4,4',4''-Tris(N-3-methylphenyl-N-phenylamino)triphenylamine Structural

What is 4,4',4''-Tris(N-3-methylphenyl-N-phenylamino)triphenylamine?

Description

With its very low solid-state ionisation potential and good-quality amorphous film, 4,4',4''-Tris[phenyl(m-tolyl)amino]triphenylamine, m-MTDATA acts as an effective material for the hole-injection buffer layer (HIL) that facilitates hole injection from the ITO electrode to the hole transporting layer (HTL). This potentially lowers the driving voltage of the OLED devices.

The Uses of 4,4',4''-Tris(N-3-methylphenyl-N-phenylamino)triphenylamine

Hole-transporting layer and Hole Injection layer material for High-Performance OLEDs.
