N2 - A double imprinting methodology was developed to synthesize novel materials with hierarchical structures. On the microporous level (1-3 Å), metal ions served as template. On the mesoporous level (diameters of 25-40 Å), micellar structures produced by self-assembly of surfactant molecules were used as templates. Removal of both metal ions and surfactant micelles resulted in the formation of imprints with different sizes within the silica matrix, each with a specific function. This research opens vast opportunities for the applications of ordered mesoporous materials in the area of molecular recognition such as separations, chemical sensors, and catalysts.
