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.
Claims22
A polymer of triarylamine monomers, said monomers having the structure 16
- wherein each of Ar1, Ar2, Ar3 is independently a substituted or unsubstituted aryl radical, or a fused ring aromatic compound consisting of said radicals, and wherein one of Ar1, Ar2 and Ar3 is a vinylated phenyl group.
A polymerizable monomer comprising a triarylamine radical, a linker group, and a cyclic olefin, said cyclic olefin being capable of undergoing a ring-opening polymerization reaction, and said linker component being covalently attached to the triarylamine component and to the cyclic olefin, wherein said triarylamine has the structure 18
- wherein each of AR1, AR2, AR3 are independently a substituted or unsubstituted aryl radical, or a fused ring aromatic compound consisting of said radicals.
