TLDR
In this paper, a mesoporous benzene−silica composite having molecular-scale periodicity in the pore wall from the self-assembly of nonlinear symmetric 1,3-bis(triethoxysilyl)benzene and octadecyltrimethylammonium surfactant is described.Abstract:
Synthesis of a highly ordered, two-dimensional hexagonal (P6mm) mesoporous benzene−silica composite having molecular-scale periodicity in the pore wall from the self-assembly of nonlinear symmetric 1,3-bis(triethoxysilyl)benzene and octadecyltrimethylammonium surfactant is described. The synthesis of hybrid organosilicas with mesoscopically ordered pores and molecularly ordered pore walls is not confined only to the symmetrically linear bridged organosilane precursors such as 1,4-bis(triethoxysilyl)benzene but a similar arrangement can also be formed by using nonlinear symmetric bridged organosilane precursors.read more

Titanium-containing mesoporous molecular sieves for catalytic oxidation of aromatic compounds
TL;DR: The use of the templating approach to synthesize mesoporous silica-based molecular sieves partly substituted with titanium—large-pore analogues of titanium silicalite find that these materials show selective catalytic activity towards the oxidation of 2,6-ditert-butyl phenol to the corresponding quinone and the conversion of benzene to phenol.

Periodic mesoporous organosilicas with organic groups inside the channel walls
TL;DR: In this article, a periodic mesoporous organosilica containing bridge-bonded ethene groups directly integrated into the silica framework is described, which is able to solvent-extract and ion-exchange the surfactant templates to create a stable and periodic mesophorous ethenesilica.

Novel Mesoporous Materials with a Uniform Distribution of Organic Groups and Inorganic Oxide in Their Frameworks
TL;DR: In this article, the synthesis of highly ordered organic-inorganic hybrid mesoporous materials is described. But the synthesis procedure to polymerize the organosilane monomer containing two trialkoxysilyl groups in the presence of surfactant can be applied to synthesize a variety of high-order mesopore materials.
