Abstract
A novel uracil-functionalized poly(3-thiophene) as a hole-injecting/ transporting layer in an organic light-emitting device is able to form physical crosslinkages resulting in high thermal stability, non-corrosion, excellent hole injection/transport and electron-blocking capabilities in the solid state, and it achieves up to 10 times higher performance than that of conventional poly(3-thiophene)s under similar experimental conditions. © 2012 The Royal Society of Chemistry.
