Available in PDF, EPUB and Kindle. Book excerpt: This book provides a comprehensive overview of the fundamental properties, preparation routes and applications of a novel class of organic–inorganic nanocomposites known as periodic mesoporous organosilicas (PMOs). Mesoporous silicas are amorphous inorganic materials which have silicon and oxygen atoms in their framework with pore size ranging from 2 to 50 nm. They can be synthesized from surfactants as templates for the polycondensation of various silicon sources such as tetraalkoxysilane. In general, mesoporous silica materials possess high surface areas, tunable pore diameters, high pore volumes and well uniformly organized porosity. The stable chemical property and the variable ability for chemical modification makes them ideal for many applications such as drug carrier, sensor, separation, catalyst, and adsorbent. Among such mesoporous silicas, in 1999, three groups in Canada, Germany, and Japan independently developed a novel class of organic–inorganic nanocomposites known as periodic mesoporous organosilicas (PMOs). The organic functional groups in the frameworks of these solids allow tuning of their surface properties and modification of the bulk properties of the material. The book discusses the properties of PMOs, their preparation, different functionalities and morphology, before going on to applications in fields such as catalysis, drug delivery, sensing, optics, electronic devices, environmental applications (gas sensing and gas adsorption), biomolecule adsorption and chromatography. The book provides fundamental understanding of PMOs and their advanced applications for general materials chemists and is an excellent guide to these promising novel materials for graduate students majoring in chemical engineering, chemistry, polymer science and materials science and engineering.

Download or read book Periodic Mesoporous Organosilica written by Steven Edward Dickson and published by . This book was released on 2011 with total page 458 pages. Available in PDF, EPUB and Kindle. Book excerpt: There is currently a great interest in the field of porous organosilica materials because of the high surface areas (> 1000 m2/g) and narrow pore size distributions which are beneficial for applications such as chromatography, chiral catalysis, sensing or selective adsorption. Periodic mesoporous organosilicas (PMOs) represent an interesting class of hybrid silica materials because of the wide variety of bridging organic groups which can be incorporated within the precursors [(OR)3Si-R-Si(OR)3] giving rise to materials with exceptional properties. We have synthesized and characterized various aromatic PMOs composed of supporting structural monomers (phenylene- or biphenylenebridged) and functional stilbene monomers (cis and trans) (1, 2). The effect of the different synthetic procedures and varying amounts of functional stilbene monomer on the properties of the materials was examined. The functional transstilbene component was determined to be well distributed in a phenylene-bridged PMO using P123 as a pore template from TEM techniques with Os staining. The trans-stilbene linkers were completely transformed to aryl aldehydes through ozonolysis with dimethylsulfide workup. Further transformation of the carbonyl functionality to an aryl imine showed a moderate level of success. Enantiomeric forms of a novel, chiral PMO precursor (CM) were synthesized and incorporated into biphenylene-bridged PMOs. Under basic pH conditions templated with C18TMACl, although very low levels of CM are incorporated, enantiomeric forms of chiral, porous materials are obtained as was verified by distinct mirror-image circular dichroism spectra. Powder XRD patterns suggest that a tightly packed asymmetric biphenylene arrangement may be necessary for the optical activity. Preliminary results using these materials as a chiral chromatographic phase are promising. Finally, a thin film morphology of an ethane-bridged PMO incorporating a thiol ligand, (3-mercaptopropyl)trimethoxysilane, was prepared on a fibre optic cable and used as a component in a heavy-metal sensing application.

Available in PDF, EPUB and Kindle. Book excerpt: Periodic mesoporous material is a class of solids that possess periodically ordered pores with sizes of 2--50 nm. After a brief introduction to the synthesis, structure, property and function of periodic mesoporous materials in general in Chapter 1, a specific type of periodic mesoporous material, periodic mesoporous organosilica (PMO), is examined in detail in Chapter 2. Chapter 3 and Chapter 4 focus on the application of periodic mesoporous organosilica as low-dielectric-constant (low-k) insulating materials on semiconductor microprocessors. Specifically, Chapter 3 introduces a vapor-phase delivery technique, vacuum-assisted aerosol deposition, for the synthesis of PMO thin films; Chapter 4 studies one property crucial for the application of low-k PMO in detail--hydrophobicity. The focus of Chapter 5 turns to a novel sandwich-structured nanocomposite made of periodic mesoporous silica and graphene oxide. In Chapter 6, progress towards the synthesis of periodic mesoporous quartz is summarized. A conclusion and an outlook are given in Chapter 7.
