This review gives an overview of current trends in the investigation of small guest molecules, confined in neat and functionalized mesoporous silica materials by a combination of solid-state NMR and relaxometry with other physico-chemical techniques. The reported guest molecules are water, small alcohols, and carbonic acids, small aromatic and heteroaromatic molecules, ionic liquids, and surfactants. They are taken as characteristic role-models, which are representatives for the typical classes of organic molecules. It is shown that this combination delivers unique insights into the structure, arrangement, dynamics, guest-host interactions, and the binding sites in these confined systems, and is probably the most powerful analytical technique to probe these systems.
这篇综述通过固态 NMR 和弛豫率与其他物理化学技术的结合，概述了当前对小分子客体在纯的和功能化介孔硅材料中进行研究的趋势。报道的客体分子有水、小分子醇和碳酸、小分子芳香族和杂芳香族分子、离子液体和表面活性剂。它们被作为典型的有机分子类别代表的典型模型化合物。结果表明，这种组合为这些受限体系中的结构、排列、动力学、客体-主体相互作用以及结合位点提供了独特的见解，并且可能是探测这些体系最强大的分析技术。
