Organosilicon polymers, including polysilanes and polycarbosilanes, have been drawing attention lately because they exhibit photo-conductivity, luminescence and other functions as well as high thermal stability. Research is moving forward to develop new synthetic methods for these new silicon polymers and to clarify the relationship between their structure and physical properties. We have succeeded in developing a Nd complex catalyst for dehydrogenative-condensation, the ring-opening alternating copolymerization of cyclic silicon compounds and quinones, technology for modifying the polymer backbones by double silylation, and a method for synthesizing ladder polymers by dehydrogenative double silylation. The Institute also studies the relationship between structure and physical properties by using amphiphilic polysilane for the preparation and orientation control of LB films, preparing thin films by the vapor phase deposition method, and using various deposition methods to control higher structures.
