摘要
The present disclosure provides porous carbon-heteroatom-silicon inorganic/organic homogenous copolymeric hybrid materials, methods for their preparation, and uses thereof, e.g., as chromatographic separations materials. The present disclosure also provides methods of preparing porous inorganic/organic homogenous copolymeric hybrid materials, comprising two or more repeat units, comprising (a) preparing a polyoligomeric siloxane (POS) by partial condensation of tetraalkoxysilane, adding a heterocyclic silane, and further reacting the heterocyclic silane with the POS to thereby prepare a porous inorganic/organic homogenous copolymeric hybrid material, comprising a carbon-heteroatom-silicon functionality or (b) partially condensing an organic olefin, an alkenyl functionalized silane, an alkoxysilane, or a heterocyclic silane, or mixtures thereof, adding a heterocyclic silane, and further reacting the heterocyclic silane with the partially condensed polymer to thereby prepare a porous inorganic/organic homogenous copolymeric hybrid material comprising a carbon-heteroatom-silicon functionality.
