Abstract

Well-defined multifunctional polymers, bearing charge transporting (CT) and nonlinear optical (NLO) functionality covalently attached to each repeat unit, were synthesized and characterized. A series of polysiloxanes were prepared that possessed either diarylamine, carbazole, or triarylamine CT moieties. High Tg polyurethanes, comprised of alternating CT and NLO units, were synthesized from NLO functionalized diols and N,N-bis(4-isocyanatophenyl)aniline. Polyimides, exhibiting high thermal stabilities, were obtained from a fluorinated dianhydride and a multifunctional (CT and NLO) diamine. Polymers were prepared containing two NLO chromophores per repeat unit, thereby doubling the NLO chromophore density over conventional NLO materials.
