Abstract

A material and method for producing mesostructured materials with multiple functionalities that are independently adjustable and collectively optimizable is provided. The method uses a series of discrete synthesis steps under otherwise mutually incompatible conditions, e.g., from acidic, alkaline, and/or non-aqueous solutions, allows different functionalities to be introduced to the materials and optimized. To illustrate the method, cubic mesoporous silica films were prepared from strongly acidic solutions that were separately functionalized under highly alkaline conditions to incorporate hydrophilic aluminosilica moieties and under non-aqueous conditions to introduce perfluorosulfonic-acid surface groups.
