Abstract

We describe the synthesis and characterization of ordered mesoporous silica using the template 1H,1H,2H,2H-perfluorooctylpyridinium chloride. This surfactant forms several lyotropic mesophases at room temperature, including hexagonal close packed cylinders, an isotropic liquid crystal, and a lamellar phase. Using this surfactant, mesoporous silica is synthesized by room temperature precipitation and surfactant extraction. Both the surfactant and product material are thoroughly characterized. From nitrogen adsorption, the product has a specific surface area of 982 m 2/g and a pore diameter of 2.6 nm. X-ray diffraction and transmission electron microscopy confirm two-dimensional close-packed hexagonal long-range ordering. This is the first example of cationic fluorinated surfactant templating of an ordered porous ceramic material.
