Sulfonic acid-functionalized mesoporous silica (SBA-Pr-SO3H) as solid acid catalyst in organic reactions

One-pot solvent-free synthesis of pyranonaphthoquinone-fused spirooxindoles catalyzed by SBA-IL

“…Besides their use as catalysts [3], modi ed SBA-15 silica materials are considered as a promising class of materials in various areas including chemosensors [4,5], adsorbents [6], gas storage [7], drug delivery [8,9], etc. Among di erent organically modi ed SBA-15 materials, immobilization of Ionic Liquids (ILs) onto solid-based materials has received signi cant attention of researchers.…”

A Schiff base‐grafted nanoporous silica material as a reversible optical probe for Hg2+ ion in water

“…Nanoporous silica materials are ideal supports for a wide variety of applications, such as catalysis, solid phase microextraction, and optical probes due to their high specific surface area, biocompatibility, hydrothermal and thermal stability, uniform open pores, thick walls, and optical transparency . Recently, grafting organic moieties onto the pore walls of nanoporous materials and utilizing them as optical probes have attracted a great deal of attention .…”

Selective detection of Hg2+ ion in aqueous medium with the use of 3‐(pyrimidin‐2‐ylimino)indolin‐2‐one‐functionalized SBA‐15

“…The incorporation of various organic groups into inorganic building blocks such as mesoporous silica materials can be an effective way for preparing hybrid materials with attractive optical properties. Mesoporous SBA‐15 silica with large surface area, adjustable pore size, excellent chemical and mechanical resistance and easy recyclability is an ideal inorganic scaffold for building organic–inorganic hybrid materials . SBA‐15 materials are non‐fluorescent and have a high surface area covered with abundant hydroxyl groups accessible for covalent grafting of organic compounds on the silica wall .…”
