Applications · 1 item

DescriptionN,N'-Dimethylquinacridone (DMQA) is a green dopant material used in OLEDs. Highly stable andlonger-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.
