19205-19-7 Usage
Classification
Green dopant materials, OLEDs, Photodetectors, Organic electronics.
Applications
N,N'-Dimethylquinacridone (DMQA) is a green dopant material used in OLEDs. Highly stable and longer-lifetime OLED devices have been achieved by using DMQA as the dopant to a double host (aminoanthracene and Alq3). It is believed that DMQA can prevent excimer formation, thus prolonging the the lifetime of the devices.
By using DMQA as a green dopant, very high efficiency OLEDs with a luminance of greater than 88,000 cd/m2, EQE of 5.4% and current efficiency of 21.1 cd/A have been achieved. DMQA has also been used in green light photodetectors for practical applications, such as photo sensors and chemical sensors.

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.
