研究了一种含盐聚合物氧化传输层（OTL）在Alq 3基多层有机发光二极管（OLED）器件中的空穴注入和传输特性。OTL包含含芳二胺的空穴传输聚合物粘合剂和相应的低分子量自由基阳离子盐。我们在这里证明，OTL的行为就像一个可调电阻器的空穴，其空穴传输特性可以控制的盐浓度和厚度的OTL。基于对作为上述参数的函数的电流密度-电压（J-V）器件特性的仔细分析，平衡电子/空穴电流以使Alq 3的氧化降解最小化。发现在5%盐浓度下具有5000 A厚OTL的OLED器件（ITO/OTL/NPB/Alq 3/CsF/Al）在10 mA/cm 2的恒定电流下以超过1000小时的半衰期工作。具有2.5%和10%盐掺杂的类似器件显示出由于不平衡而导致的数量级的半衰期降低。
A salt containing polymer, called an oxidized transport layer (OTL), was investigated for hole injection and transport into Alq3-based multilayered organic light emitting diode (OLED) devices. The OTL comprises an aryldiamine containing hole transport polymer binder with a corresponding low molecular weight radical cation salt. We demonstrate herein that the OTL behaves like a tunable resistor for holes, and its hole-transport properties can be controlled by the salt concentration and thickness of the OTL. Based on a careful analysis of the current density–voltage (J–V) device characteristics as a function of the above parameters, electron/hole currents were balanced to minimize oxidative degradation of Alq3. It was found that an OLED device (ITO/OTL/NPB/Alq3/CsF/Al) with a 5000 A thick OTL at 5% salt concentration operated with a half-life exceeding 1000 h at a constant current of 10 mA/cm2. Similar devices with 2.5% and 10% salt doping showed an order of magnitude lower half-life attributed to unbalance...
