Mesostructured materials : Synthesis towards applications
Generally speaking, the synthesis of mesostructured materials can be controlled through altering the surfactant type (ionic or non-ionic) and the interaction mechanism between the template (if employed) and silica components. 1,2 M41S silica molecular sieves were initially synthesized under alkaline conditions, where the anionic inorganic species (I −) become stable in the presence of the Poor permeation across intestinal mucous barriers often limits the oral delivery of prospective therapeutic proteins and peptides (TPPs). In order to address this issue, cell penetrating peptide (CPP) together with PEG modified and pore-enlarged mesostructured silica nanoparticle (NP) were construct … Recently, ordered chiral mesoporous silica with a twisted hexagonal rod-like morphology and hexagonally ordered chiral channels has been synthesized by using chiral anionic surfactants as a liquid crystal template (S. Che, Z. Liu, T. Ohsuna, K. Sakamoto, O. Terasaki and T. Tatsumi, Nature, 2004, 429, 281).

The main objective of this project has been to investigate syntheses of mesostructured silica using non-ionic block co-polymers as
Since its discovery in 1992, mesostructured silicate particles have been a subject of intensive research due to the large surface areas of the materials and the simplicity in modifying both the particle and the pore size. 38, 39 Various organic templates (e.g., cationic surfactants and triblock copolymers) and pore swelling agents have successfully been used in the particle synthesis to give a wide range of well‐defined pore sizes and mesostructures. 40, 41 Furthermore, the versatility of
The inorganic matrix in the mesostructured materials can be varied. Most commonly used are SiO2 (silica) and TiO2 (titanium dioxide), but also other types of metal oxides have been used such as aluminium, tungsten, iron and zirconium oxide. The inorganic matrix is formed through polymerization of

Che, Z. Liu, T. Ohsuna, K. Sakamoto, O. Terasaki and T. Tatsumi, Nature, 2004, 429, 281).In this work, we report an observation of hierarchically helical mesoporous silica Mesostructured silica particles (∼100 nm diameter with ∼2 nm pores) prepared by surfactant-templated sol–gel techniques are versatile supports that can be easily derivatized with active molecules to create multifunctional materials. By deliberately placing active molecules in different regions of the mesostructure, fluorescent molecules, molecular machines, targeting ligands, and metal of mesostructured thin films to determine the value for the electron tunneling decay constant of mesostructured silica is described. Another major application of the silica structure, its use as a framework for molecular machines, is then discussed. Rotaxanes and azobenzenes are attached to mesoporous silica and used as valves and impellers in Yolk‐shell‐mesostructured silica was used as a support in the development of an active‐site‐isolated bifunctional catalyst that can mediate a sequential organic transformation.
