摘要: This study describes a novel method for manufacturing a hole injection layer of an organic light-emitting diode (OLED), comprising an ultraviolet (UV) reactive Br-fluorocarbon precursor (Br-CF2-C6F4-CF2-Br). The proposed method can be used to form a fluorizated polyxylylene film, demonstrating high repeatability on the anode as the hole injection layer of organic electroluminescent devices to enhance the hole injection, reduce the operating voltage of 1.2 V, and extend the operational lifetime by more than 150 times under a high current density of 125 mA/cm(2). Using a spin-coating process, the remaining precursor can be recycled to prevent wasting materials. UV curing without the solvent-removing process shortens manufacturing time. Hence, fabricating a high performance OLED using a simple, low-cost process is the aim of this study. (C) 2012 The Japan Society of Applied Physics
