Fig. 9 Schematic representation of three approaches to generate nanoporous and meso-porous materials with block copolymers, a Block copolymer micelle templating for mesoporous inorganic materials. Block copolymer micelles form a hexagonal array. Silicate species then occupy the spaces between the cylinders. The final removal of micelle template leaves hollow cylinders, b Block copolymer matrix for nanoporous materials. Block copolymers form hexagonal cylinder phase in bulk or thin film state. Subsequent crosslinking fixes the matrix hollow channels are generated by removing the minor phase, c Rod-coil block copolymer for microporous materials. Solution-cast micellar films consisted of multilayers of hexagonally ordered arrays of spherical holes. (Adapted from [33])...

As mentioned previously, mesoporous inorganic materials can be formed by one of two reaction pathways, liquid-crystal templating and cooperative self-... 

Stucky s mechanism can explain more experimental results in a wide range. After improvements/151 it guides the synthesis of mesoporous inorganic materials. In fact, the initial basis of Stucky s mechanism is the charge-density-matching model based on the fact of phase transformation from lamellar phase to hexagonal phase. 

A great deal of knowledge can be found in the reported research dealing with synthesis of azobenzene-functionalized mesoporous inorganic materials (Alvaro et al. 2005 Besson et al. 2005 Liu et al. 2004) and with detailed investigations into azobenzene cis/trans isomerization in mesostructured silica (Sierocki et al. 2006).
