In addition, one of the main areas in PMO is organically functionalized PMO (hybrid periodic mesoporous organosilica (HPMO)) [43, 44] (Figure 3.3). Organically functionalized PMO is currently an area of intensive research because of its unique properties and potential applications.

Functionahzed Periodic Mesoporous Organosilicas (PMOs) can act as a solid acid catalyst. PMOs exhibit large specific surface areas, pore diameters of 2-50 nm and narrow pore size distributions. They are mostly synthesized with bridged bis-silanes with a general stracture (EtO)3-Si-R-Si-(OEt)3 (Figure 1) This bis-silane polycondensates around a template such as the surfactant PI23 (EO)2o(PO)7o(EO)2o After formation of the PMO, the template is removed by an extraction to reveal the pores of the hybrid material. ...

Since the discovery of this first benzene-bridged mesoporous hybrid material with crystal-like pore walls, the series of organosilica precursors that give PMOs exhibiting molecular-scale periodicity was considerably extended. Kapoor et al. demonstrated with the formation of PMO products from the precursor 1,3 -bis(triethox-ysilyl)benzene (10) that a crystal-like organization of the organic bridges within the pore walls is not restricted to linear-substituted precursors.264...
