ABSTRACT:  We synthesized sugar-polysiloxane hybrids having rigid main-chains by reaction of sugar-lactones with amine-functionalized polysiloxane (1). Reaction of gluconolactone (2) with 1 was performed to obtain polysiloxane (3) having polyol moieties derived from glucose. This material has the regularly controlled higher-ordered structure in solid state such as the hexagonal phase. A hydrophilic sugar-polysiloxane hybrid (5) was prepared by reaction of lactobionolactone (4) with 1. Furthermore, an amphiphilic sugar-polysiloxane hybrid (8) was synthesized by introduction of stearoyl groups in addition to sugar groups on the surface of 1. The SEM image of the amphiphilic material 8 exhibited formation of nano aggregates having the particle diameters of ca. 50 nm in water.
