Description
N,N'-Dimethylquinacridone (DMQA) is a green dopant material used in OLEDs, characterized by its yellow to yellow-red solid appearance. It is highly stable and contributes to the creation of longer-lifetime OLED devices when used as a dopant in a double host system consisting of aminoanthracene and Alq3. The chemical's ability to prevent excimer formation is believed to be the key factor in extending the lifetime of these devices.
Uses
Used in Organic Light Emitting Diodes (OLEDs):
N,N'-Dimethylquinacridone is used as a green dopant in OLEDs for its ability to achieve highly stable and longer-lifetime devices. The incorporation of DMQA into a double host system has resulted in OLEDs with exceptional performance metrics, including a luminance of greater than 88,000 cd/m2, an external quantum efficiency (EQE) of 5.4%, and a current efficiency of 21.1 cd/A.
Used in Green Light Photodetectors:
In the field of optoelectronics, N,N'-Dimethylquinacridone also serves as a component in green light photodetectors, which are essential for various practical applications. These include photo sensors and chemical sensors, where the material's properties contribute to the efficiency and effectiveness of these devices in detecting and responding to green light.

Check Digit Verification of cas no
The CAS Registry Mumber 19205-19-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,2,0 and 5 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 19205-19:
(7*1)+(6*9)+(5*2)+(4*0)+(3*5)+(2*1)+(1*9)=97
97 % 10 = 7
So 19205-19-7 is a valid CAS Registry Number.
