Structural relation properties of hydrothermally stable functionalized mesoporous organosilicas and catalysis
Article Abstract:
The surfactant assistant syntheses of sulfonic acid functionalized periodic mesoporous organosilicas with large pores are reported. The role of the bridged organic group on the hydrothermal stability of the mesoporous materials was established which revealed an enhancement in hydrothermal stability of the materials with incorporation of the bridged organic groups in the network.

Organosilica copolymers for the adsorption and separation of multiple pollutants
Article Abstract:
Benzene, diethylbenzene, and ethylenediamine-bridged bistrialkoxy precursors were used in the synthesis of multifunctional periodic mesoporous organosilicas (PMO) copolymers for the adsorption of phenols and metal ions. It is concluded that aromatic and metal chelating bridging groups could incorporate into PMO copolymers while maintaining an ordered pore structure.

Structural characterization of mesoporous organosilica films for ultralow-k dielectrics
Article Abstract:
A method to control the hydrophobicity and dielectric constant of mesoporous silica films for ultralow-k applications is described. Cationic and nonionic surfactants were used as sacrificial materials in silicate matrixes, prepared from tetraethoxysilane and methyl trimethoxysilane.
