Application

N,N'-Dimethylquinacridone (DMQA), purified by sublimation, serves as a crucial green dopant in OLED technology. This yellow to yellow-red solid has been instrumental in creating highly stable OLED devices with extended lifespans due to its ability to prevent excimer formation. When used as a dopant alongside a double host system of aminoanthracene and Alq3, DMQA facilitates the production of OLEDs with impressive efficiencies, achieving luminance levels over 88,000 cd/m², external quantum efficiency (EQE) of 5.4%, and a current efficiency of 21.1 cd/A. Additionally, DMQA's utility extends to green light photodetectors, making it suitable for practical applications such as photo sensors and chemical sensors.
