Bridged organosilane precursors

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...

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.
