Description and Uses

4,4',4''-Tris[2-naphthyl(phenyl)amino]triphenylamine (2-TNATA), a starburst type molecule, gives very homogeneous thin-films that are ideal as hole-injection?layers due to its low ionisation potential (of around 5.1 eV ).

It is a famous hole transport material which could be utilized for high performance and high-efficiency OLED devices. Colors contain white light and deep blue，meanwhile the lifetimes are much more efficient (resulting efficiency was 6.0 lm/W (12.4 cd/A) a
