This paper reports on hybrid organic-inorganic dense membrane materials in which protons and ions are envisioned to diffuse along the hydrophilic pathways. The hierarchical generation of functional hybrid materials was realised in two steps. First, the self-assembling properties of 3-(ureidoarene)propyltriethoxysilane compounds 1-5 in aprotic solvents were determined, revealing the formation of supramolecular
Biogenic formation of silica is a fundamental process occurring under mild conditions. Here we report autocatalytic generation of silicahybrid materials. Self-organized siloxanes containing imidazole self-catalytic groups can be transformed to hybridsilica by using mild biomimetic conditions similar to those under which primitive organisms make silica.
