A facile synthetic method was developed to prepare sub-5 nm organo-silica (oSiO2) nanoparticles through the self-condensation of atom transfer radical polymerization (ATRP)-initiator-containing silica precursors. The obtained oSiO2 nanoparticles were characterized by a combination of NMR, thermogravimetric anal. (TGA), transmission electron microscopy (TEM), dynamic light scattering (DLS), and small-angle neutron scattering (SANS). The accessibility of the surface-Br initiating sites was evaluated by the polymerization of poly(Me methacrylate) (PMMA) ligands from the surface of the oSiO2 nanoparticles using surface-initiated atom transfer radical polymerization (SI-ATRP). The ultrasmall size, tunable composition, and ease of surface modification may render these organo-silica nanoparticle systems with built-in SI-ATRP capability an interesting alternative to conventional silica nanoparticles for functional material design. The experimental part of the paper was very detailed, including the reaction process of 5-Hexen-1-ol(cas: 821-41-0SDS of cas: 821-41-0)
5-Hexen-1-ol(cas: 821-41-0) is used in cyclization to a tetrahydropyran by phenylselenoetherification. It is also used as a building block in synthetic chemistry.SDS of cas: 821-41-0
