185690-41-9

4,4',4''-Tris[2-naphthyl(phenyl)amino]triphenylamine (2-TNATA) is a starburst type molecule known for its homogeneous thin-films, which are ideal as hole-injection layers due to its low ionization potential of around 5.1 eV. This organic compound is characterized by its blue light emission properties and is widely recognized for its use in high-performance and high-efficiency organic light-emitting diodes (OLEDs).

185690-41-9 Usage

Uses

Used in Organic Light-Emitting Diodes (OLEDs):
4,4',4''-Tris[2-naphthyl(phenyl)amino]triphenylamine is used as a hole transport material for OLEDs, contributing to high performance and efficiency. It is particularly effective in devices that emit white light and deep blue, with significantly improved lifetimes and power efficiency. The resulting efficiency in OLED devices can reach up to 6.0 lm/W (12.4 cd/A) at 20 mA/cm2.
Used in p-i-n OLEDs with Tungsten Oxide (WO3):
In the application industry of OLEDs, 4,4',4''-Tris[2-naphthyl(phenyl)amino]triphenylamine is used as a component in p-doped transport layers, in combination with tungsten oxide (WO3). This application enhances hole injection and conductivity in Alq3-based p-i-n OLEDs, leading to long lifetimes, low driving voltage (3.1 V), and high power efficiency (3.5 lm/W) at 100 cd/m2.

Classification

Triphenylamine derivatives, Hole-injection materials, Hole-transporting materials, Light-emitting diodes.

Check Digit Verification of cas no

The CAS Registry Mumber 185690-41-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,5,6,9 and 0 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 185690-41:
(8*1)+(7*8)+(6*5)+(5*6)+(4*9)+(3*0)+(2*4)+(1*1)=169
169 % 10 = 9
So 185690-41-9 is a valid CAS Registry Number.
