Abstract : This project involves a collaborative synthetic, polymer processing, and physicochemical program directed at exploiting the unique properties of the high modulus/high strength polymers poly(p-phenylenebenzobisthiazole) (PBT) and poly- (p-phenylenebenzobisoxazole) (PBO) for electronic charge transport and nonlinear optical (NLO) properties. In the former area, we have continued our successful studies of directly doping these polymers by electrochemical means and of processing phthalocyanine/polymer hybrid materials. In the NLO area, we have continued exploration of the properties of NLO chromophore/PBT hybrid materials and of glassy macromolecules with such chromophores covalently bonded to the backbone. Initial studies of oriented NLO chromophores embedded in crosslinkable matrices have also been carried out. Approaches to inorganic/ organic hybrid NLO materials via intercalation processes are also under investigation. Keywords: Conductive polymers, Phthalocyanine, Nonlinear Optical properties, Polymer doping.
