Controlling nanostructure in periodic mesoporous hexylene-bridged polysilsesquioxanes
Source abstract
Abstract
Abstract Periodic mesoporous bridged polysilsesquioxane (PMBPS) materials are hybrid organic inorganic materials with long range order and porosity between 1–15 nm length scales and great promise as adsorbents and chromatographic materials. In this study, we describe the preparation and optimization of a class of PMBPS with hexylene-bridging groups and cubic Pm3n symmetry. These hexylene-PMBPSs were prepared by surfactant templating of the sol–gel polymerization of 1,6-bis(triethoxysilyl)hexane (BESH) with cetyltrimethylammonium bromide (CTAB) and N-(3-trimethylammoniumpropyl)hexadecylammonium dibromide (C16–3–1). Powder X-ray diffraction (XRD) and nitrogen adsorption data were used to ascertain the influence on the mesostructure as a function of monomer concentration and aging duration, and aging temperature.
