  text: The synthesis of novel robust and stable iridium-based immobilized catalysts
    on silica-polymer hybrid materials (Si-PB-Ir) is described. These catalysts are
    characterized by a combination of 1D P-31 CP-MAS and 2D P-31-H-1 HETCOR and J-resolved
    multinuclear solid state NMR experiments. Different binding situations such as
    singly and multiply coordinated phosphines are identified. Density functional
    theory (DFT) calculations are performed to corroborate the interpretation of the
    experimental NMR data, in order to propose a structural model of the heterogenized
    catalysts. Finally, the catalytic activity of the Si-PB-Ir catalysts is investigated
    for the hydrogenation of styrene employing para-enriched hydrogen gas.
