PBT, PBO-Based Hybrid Polymers with Nonlinear Optical Properties or HighElectrical Conductivity

摘要

This program has involved a combined synthetic, processing, and physicochemicalstudy of multifunctional, high-performance polymer systems rationally designed for certain unusual physical properties. In one thrust, the unique properties of the high modules/high strength macromolecules poly(p-phenylenebenzabisthiazole) (PBT) an poly (p-phenylenebisoxazolo) (PBO) have been utilized to develop new kinds of electrically conductive polymeric and molecular/macromolecular hybrid materials. In the second thrust, several complementary approaches to the construction, evaluation, and fundamental understanding of new types of high-performance nonlinear optical materials have been pursued. Areas of emphasis have included chromophore-functionalized glassy polymers, chromophore-embedded crosslinkable matrices, inorganic/organic hybrid materials, crosslinked NLO films, the design of novel chromophores, and internally ordered polymeric NLO materials. Each research component has built upon past successes as well as upon strong on-going collaborations in laser optics and quantum theory.
