Polyhedral Oligomeric Silsesquioxanes POSS are of interest because the hydrolysis and condensation of the silane precursors can be controlled to form incompletely condensed scaffolds which can then be functionalized via condensation with differing moieties. However, conventional wisdom held that isolation of ionized scaffolds was impossible due to the increased reactivity of the ionic siloxy fragments. However, recent results have shown that certain POSS based salts are indeed stable. This talk will review the progress in formation of ionic species, and the potential of these intermediates for rational synthesis of other nanostructures.
