Dipolar doping of hole transport layer (HTL) is available for controlling the density and polarity of the accumulated charge at the interfaces of organic light-emitting diodes (OLEDs) via spontaneous orientation polarization. Herein, we demonstrated some examples of dipolar doping HTLs and how they influence on the device performance of OLEDs.
