摘要：

High-efficiency white polymer light-emitting diodes are demonstrated by using a hole-injection/transport bilayer. The excellent solvent resistance of the fully crosslinked hole-injection layer ensures the subsequent solution processing of the light-emitting layer. High power efficiency can be achieved. The device also emits quite stable white light. The figure shows a schematic of the device and the chemical structure of the VB-TCTA layer.
