Abstract

Tetra(3-mercaptopropyl)-silsesquioxanes with double-decker (DDSQ) or ladder nano-cores were easily prepared from the corresponding tetraallyl derivatives through fast and convenient thiol-ene reactions. An additional tetrathiol-DDSQ with more flexible arms was also synthesized in high yield from the corresponding tetrachloro-DDSQ derivative. The three novel tetrathiol silsesquioxanes described represent versatile building blocks for the preparation of hybrid organic-inorganic materials.

摘要

具有双层（DDSQ）或梯形纳米核的四（3-巯基丙基）倍半硅氧烷可通过快速便捷的硫醇-烯反应，由相应的四烯丙基衍生物轻松制备而成。还从相应的四氯-DDSQ衍生物高产率地合成了一种具有更灵活臂的额外四硫醇-DDSQ。所描述的三种新型四硫醇倍半硅氧烷是制备有机-无机杂化材料的通用结构单元。
