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.
