4,4',4''-Tris[2-naphthyl(phenyl)amino]triphenylamine Usage And Synthesis

Classification	Triphenylamine derivatives, Hole-injection materials, Hole-transporting materials, Light-emitting diodes.
Applications	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 has been demonstrated that p-i-n organic light-emitting diodes (OLEDs) incorporating a p-doped transport layer that comprises tungsten oxide (WO3) and 2-TNATA significantly improves hole injection and conductivity of the Alq3 based p-i-n OLEDs with long lifetime, low driving voltage (3.1 V), and high power efficiency (3.5 lm/W) at 100 cd/m2.
Description	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 ).
Uses	N1-(naphthalen-2-yl)-N4,N4-bis(4-(naphthalen-2-yl(phenyl)amino)phenyl)-N1-phenylbenzene-1,4-diamine (CAS# 185690-41-9) is a blue light emitter and is used in organic light-emitting diodes (OLEDs).
Uses	This material is a very popular hole transport material used in high performance; high-efficiency OLED devices. Colors include white light and deep blue with much more efficient lifetimes (resulting efficiency was 6.0 lm/W (12.4 cd/A) at 20 mA/cm2).
Uses	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
