A series of photo-crosslinkable arylamine-based hole-transport copolymers has been synthesized. The synthetic methodology employed allows for the redox potential of the polymer to be tuned by the incorporation of electron-donating or -withdrawing moieties. Upon exposure to ultraviolet radiation, the polymers become insoluble, as evidenced by UV/Vis absorption spectroscopy, a feature that is useful for the fabrication of multilayer organic light-emitting diodes (OLEDs) by solution processing techniques. OLEDs based on these hole-transport polymers have been fabricated and the performance of the devices has been evaluated. The photo-crosslinking process has been optimized so that it no longer adversely impacts device performance.
已经合成了一系列可光交联的芳胺基孔导电共聚物。所采用的合成方法允许通过引入电子供体或吸电子基团来调节聚合物的红氧还原电位。在紫外线辐射照射下,聚合物变得不溶,用UV/Vis吸收光谱学证明了这一点,这一特性对通过溶液处理技术制造多层有机发光二极管(OLED)非常有用。基于这些孔导电聚合物的OLED已经被制造,并对器件性能进行了评估。光交联过程已得到优化,以至于不再对器件性能产生负面影响。
