The present invention relates generally to hybrid organic-inorganic adsorbents for decontamination of fluids. Bridged poysilsesquioxanes are a family of hybrid organic-inorganic materials prepared by sol-gel processing of monomers that contain a variable organic bridging group and two or more trifunctional silyl groups. Specifically, the present invention relates to dipropylenedisulfide-co-phenylene-bridged polysilsesquioxane compositions, methods of making dipropylenedisulfide-co-phenylene-bridged polysilsesquioxanes, and methods of use of dipropylenedisulfide-co-phenylene-bridged polysilsesquioxanes. The present invention discloses properties of dipropylenedisulfide-co-phenylene-bridged polysilsesquioxanes that include high ligand loading, increased surface area, and increased porosity. These properties make dipropylenedisulfide-co-phenylene-bridged polysilsesquioxanes excellent adsorbents for decontamination of fluids for use in environmental and industrial processes.
