Figure 15. Rh-containing organosilane precursor 2 incorporated into mesoporous silica through postmodification and one-pot synthesis [76].

Cyclopolysilanes bearing several different substituents can be assembled in a step-by-step procedure from small appropriately substituted organosilane precursor molecules. An example originally presented by Uhlig16 and modified later in order to obtain the reaction product free of polymers17 is shown in Scheme 1, where... 

Figure 3.7 Schematic of the incorporation of organic groups in the pore walls of mesoporous silica using bridged organosilane precursors (top). Schematic of the structure of a phenylene-bridged hybrid mesoporous organosilica with both atomic and mesoporous periodicity (bottom) [36],...

Inspired by the use of bridged organosilane precursors to homogenously introduce chemical functionalities in the walls of mesoporous materials, our group has... 

The range of organosilane precursor structures potentially available for the synthesis of hybrid mesoporous (and mesostructured) materials is extremely large development of new material compositions will continue to be a fertile area of research.

The different approaches used to synthesize sulfonated polysiloxanes can be distinguished according to synthesis/modification of the solid siliceous network, to the organosilane precursor used, and to the generation of the active sulfonic acid group, as given in Figure 1.

Table 18.3 Selected bridged organosilane precursors used in the synthesis of PMOs with crystal-like wall pore.

Kapoor et al [131] demonstrated that the synthesis of hybrid organosilicas with mesoscopically ordered pores and molecularly ordered pore walls was not confined to symmetrically linear bridged organosilane precursors, but a similar arrangement could also be obtained with nonlinear symmetric bridged organosilane precursors, such as 1,3-BTEB.
