摘要：这篇综述概述了限域分子（如高级醇、乙二醇和聚乙二醇）作为纯功能化介孔二氧化硅材料中的客体分子的研究趋势。所有这些分子都具有疏水性和亲水性部分。它们是限域表面活性剂研究的典型榜样。通过将固态核磁共振和弛豫测量与其他物理化学技术和分子动力学技术相结合来研究它们的特性。结果表明，这种组合为限制内的结构、排列、动力学特性和宾主相互作用提供了独特的见解。
Abstract This review gives an overview of current trends in the investigation of confined molecules such as higher alcohols, ethylene glycol and polyethylene glycol as guest molecules in neat and functionalized mesoporous silica materials. All these molecules have both hydrophobic and hydrophilic parts. They are characteristic role-models for the investigation of confined surfactants. Their properties are studied by a combination of solid-state NMR and relaxometry with other physicochemical techniques and molecular dynamics techniques. It is shown that this combination delivers unique insights into the structure, arrangement, dynamical properties and the guest-host interactions inside the confinement.
