Bis-silanol is one of the most useful precursors for the synthesis of siloxane-based polymers. However, the development of such siloxanes materials has been impeded because of the limited accessibility of bis-silanols monomers. Here in this presentation, we will describe a mild and highly efficient synthesis of bis-silanols via oxidation of bis-hydrosilanes using Pt-nanocluster catalysts. A highly selective transformation of silanes to corresponding silanols was observed with no formation of disiloxane products. All polymer products were well characterized by multinuclear NMR spectroscopy. The chain length properties were obtained by GPC technique. The thermal and elastomeric properties of such polymers were studied by techniques such as TGA-DTA, DSC and TMA.
