Abstract
Modification of polymer light-emitting diodes indium tin oxide (PLED ITO) anode with a silyl-functionalized triarylamine hole-transporting AM leads to two orders of magnitude enhancement in the maximum luminance and quantum efficiency for a single-layer PFO-based blue PLED device. Even compared to a device with PEDOT-PSS as the HTL, the SAM-based device exhibits ∼3 times higher maximum luminance, as well as comparable quantum and power efficiencies. While good hole-injection capacity was shown to be an important factor in the improved performance, other SAM characteristics, such as ultra-low visible absorption, lower active layer thickness, and high interfacial stability were additional attractions.
