Synthesis and characterization of novel spiro penta- and hexacoordinate anionic polysiliconate and polygermylate ionomers derived from the condensation of ({plus_minus}) 5,5{prime}, 6,6{prime} - Tetrahydroxy-1,1{prime} - spiro-bis(Indane) with trialkoxysilanes, tetraalkoxysilanes, and trialkoxygermanes
Synthesis of hybrid organic-inorganic materials with ionic functionality within the polymer backbone has been achieved. A new family of hypervalent spiro anionic polysiliconates and polygermylates has been prepared. These materials were shown to be thermally stable to moderate temperatures and are completely air and moisture stable. Analysis by solution and solid state NMR verified the presence of the hypervalent functionality. We are currently examining the effect that alteration of the condensing reagent and/or the counterion may have on bulk properties of the ionomeric material.
