  • Hole-transporting polymers
    Publication number: 20010017155
    Abstract: Polymers comprising triarylamine substituent monomers. The polymers are products of anionic or radical polymerization of monovinylated triarylamine monomers or of ROMP polymerization of monomers comprising a triarylamine component, a linker component, and a cyclic olefin that is capable of undergoing a ring-opening polymerization reaction. The resulting polymers possess hole-transporting properties and are useful as hole transport layers in light-emitting diodes or as components of photorefractive materials.
