    Abstract

    A new type of silicaorganic hybrid nanoparticle (HNPs) ~30nm in size, consisting of vinylsilylated silica nanoparticles (SNPs) of size ~2nm and 1,6-hexanedithiol as the organic linker, were prepared by their interconnection via the thiolene reaction. The particle size of the HNPs varied depending on the concentration of the linker. Additionally, they could be dispersed in organic solvents and further successful chemical modification of the internal surfaces of HNPs indicated the accessibility of guest species into the internal nanospaces.
