Highly Polyfunctional Silsesquioxanes
Abstract
The use of silsesquioxanes as Ňnano-building blocksÓ offers multiple exciting avenues of research in each of these areas as well as many that cannot be discussed here because of space limitations. Our goal in this talk will be to discuss methods whereby it is possible to generate single octaphenylsilsesquioxane derivatives that can have eight, sixteen and even 24 reactive sites in the same volume permitting the introduction of as many as 24 different reactive groups or just increasing the number density of a single type of reactive group or mixtures somewhere in between these end points. We discuss here the synthesis and chemistries of the oligomeric molecules [BrPhSiO1.5]8, [Br2PhSiO1.5]8, [Br3PhSiO1.5]8 and [Br2PhSiO1.5]12 used as starting points for the creation of 3-D nanostructures. We will also discuss their use in the synthesis of mixed functionality phenylsilsesquioxanes systems.

Major research areas for the Laine group include synthesis and processing of hybrid polymers and nano-oxide powders. Research in the hybrid area emphasizes the preparation and characterization of nanobuilding blocks based on polyfunctional octahedral (octafunctional) and dodecahederal (dodecafunctional) silsesquioxanes (POSS) and nanocomposites therefrom wherein the periodicity and ordering of the inorganic and organic components are completely defined on a nanometer length scale. Research on nanooxides emphasizes the direct synthesis of single and mixed-metal nanopowders by flame spray pyrolysis of mixed-metal metalloorganics. The resulting powders and the effects of processing conditions on the photonic and structural properties of these powders and monoliths made from them are of primary interest. This research has been the basis of three spin-off companies.
