Abstract : This final report summarizes research works on photorefractive materials which are single chain, fully functionalized polymers. Three polymeric systems were described, namely, functionalized polyurethanes, functionalized conjugated polymers and polyimides containing porphyrin moieties. Detailed synthetic procedures were outlined. Extensive physical studies, including photoconductivity measurements, electro-optic measurements and two beam coupling studies were carried out. The results revealed the unique features for fully functional, photorefractive polymers. This work also lead to the development of a novel synthetic methodology for polycondensation by utilizing the Stille coupling reaction. (MM)
