چکیده انگلیسی
Highly efficient organic light-emitting diode have been developed by using a fluorinated quinacridone derivative: N,N′-di(n-butyl)-2,9-difluoroquinacridone doped in Alq3 as the emitting layer. The device shows much lower driving-voltage (the turn-on voltage is 2.5 V, the practical brightness of 100 and 1000 cd m−2 are realized at 3.2 and 4.2 V, respectively) and higher power efficiency (the peak value of 15.2 lm W−1 is obtained at 4 V and 598 cd m−2) than that of devices based on all the other QA derivatives. The pronounced EL performance enhancement might be attributed to the improved electron injection induced by introducing the strong electron-withdrawing fluorine atoms into the QA derivative.
