N,N'-Dimethylquinacridone Usage And Synthesis

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.
