The van der Waals induced supramolecular organization of hydrophobic tetrahedral units in the course of hydrolytic polycondensation
Abstract
This paper describes the hydrolytic polymerization of a tetrahedral precursor in the four directions. The hydrolytic polycondensation occurring at silicon led to highly polycondensed solids (around 100%). The solids obtained exhibited an organization at the nanometric scale evidenced by X-ray powder diffraction and another at the micrometric scale (birefringence experiments). The optical axis determination which corresponds to the orientation of the cross-linked colloids exhibits an inverse micelle type geometry. Thus the self-organization of the tetrahedral units is controlled by the poor hydrophilicity of the medium.
