Development of a Novel p-Dopant for OLED and Its Combination with HTL to Reduce Leakage Current
Invited
Description:
We investigate the synergistic effects of our newly synthesized p-Dopant with various HTL compounds. We demonstrate that the optimized combination mitigates leakage current. The p-Dopant we developed is a material with a relatively shallow LUMO, but through the combination of an appropriate HTL, the driving voltage, efficiency, and lifespan of the device are at the same level as devices using deep LUMO p-Dopant, while reducing lateral conductivity.
