Abstract
Alkoxytrichlorosilanes (ROSiCl3) were synthesized by the reaction of n-alcohols (ROH) with tetrachlorosilane (SiCl4), and partial hydrolysis and the subsequent polycondensation of alkoxytrichlorosilanes (ROSiCl3) yielded novel layered silica-organic nanocomposites. The products are composed of organic layers and silica layers stacked alternately on a nanometer length scale. The process depends on the partial hydrolysis of ROSiCl3 to form amphiphilic alkoxysilanetriols [ROSi(OH)3], which self-assemble into a bilayer structure, followed by polycondensation upon drying.
