Synthesis And Applications Of Anionic Amphiphiles

Several anionic amphiphiles were synthesized. Moreover, inorganic materials, organic-inorganic hybrid materials, and conductive materials were prepared via sol-gel methods.For inorganic materials, a variety of silica nanostructures were prepared by changing reaction conditions, such as single-handed helical mesoporous silica nanofibers, nanorods, and hollow shells. The silica nanostructures and pore architectures were also controlled via a co-template method.For organic-inorganic hybrid silicas, left-handed double twisted nanobelts were prepared using chiral anionic gelators. The aromatic rings are packing in helix within the nanobelts. Moreover, mesoporous nanobelts and nanotubes were also prepared. For conductive materials, a series of conductive polypyrroles were prepared via sol-gel transcription method. The morphologies were controlled by changing preparation conditions, such as nanosphere, leaf-like nanobelt, and hollow nanotubes. Moreover, the diameters and the lengths of the nanotube were also tunable. These polypyrroles show somewhat conductivity.The materials shown above are potential applied in chiral catalysis, chiral separate, medicine carrier, and stealth coating. Further research will be carried out in these fields.
