摘要： Disclosed is a novel organosilicon-containing derivative of pullulan of which an organopolysiloxane moiety having a silethylene linkage is bonded to the glucose residue of pullulan through a urethane linkage. Different from conventional organopolysiloxane-modified pullulans, the inventive derivative is stable against attack of water and exhibits unique properties as a combination of the properties inherent in pullulan and in silicones. The organosilicon-containing pullulan of the invention can be easily prepared under mild reaction conditions by reacting an isocyanato group-containing organopolysiloxane with the glucosic hydroxy groups of pullulan.

摘要： Disclosed are a conductive thienyl derivative monomolecular film covalently bonded to a substrate surface and method of manufacturing the same, and a silicon compound comprising 3-thienyl groups (thiophene derivative) used for forming the conductive monomolecular film and a method of manufacturing the same. A monomolecular ultrathin film comprising 3-thienyl groups and silicon groups is formed in the invention. The silicon compound used for forming the film is provided by reacting .omega.-(3-thienyl)-1-alkene compound to a monosilane derivative compound, in which three out of four hydrogen atoms of monosilane are replaced with halogen or alkoxy groups, in the presence of a transition metal catalyst. A substrate is dipped and held in a nonaqueous solution of the above-noted compound, thus chemically bonding the monomolecular film to the substrate surface. Furthermore, a thienyl derivative ultrathin film is formed by the electrolytic or catalytic polymerization of the monomolecular film.
