An approach to fabrication high-efficiency hole-transport layers (HTL) for polymer ligh-emitting diodes (PLED) was discussed. HTL fabricated by this approach had two components which include a siloxane-derivatized, crosslinkable, hole-transporting material and a hole-transporting polymer. It was found that the PLEDs that were fabricated using this PLEDs exhibit superior performance versus analogous devices using a conventional poly(3,4-ethylenedioxythiophene)- poly(styrenesulfonate) (PEDOT-PSS) HTL. The results show that, this approach has considerable flexibility and can be applied as a general strategy to manipulate energy level alignments in PLEDs.
