Crystallization in hybrid organic-inorganic materials induced by self-organization in basic conditions

摘要: Hybrid organic−inorganic crystalline materials have been obtained from a simple solvent-free synthesis in highly basic conditions. The formation of an organized hybrid structure has achieved for the first time via sol−gel without employing bridged organosilica precursors. 3-glycidoxypropyltrimethoxysilane, which is organically modified alkoxide bearing terminal epoxy group, used synthesis. opening observed to produce poly/oligo(ethylene oxide) chains or p-dioxane species. In second case hybrids formed by self-organization during gelation. Analysis performed wide-angle X-ray scattering and diffraction confirmed nature aggregates, ring opening/self-condensation resulted pillared-type with Si-substituted 2,5-bis(propoxymethyl)-1,4-dioxane organic spacer as pillar.
