An alkylimidazolium-based long-chain ionic liquid (LCIL) was immobilized in silica nanopores via a supramolecular assembly approach. To discuss the characteristic features of LCIL in a confined nanospace, except for the characteristics of the host materials, we have prepared the silica host with monodisperse morphology and a nanostructured system to immobilize LCIL. The nanostructure is composed of three distinct regions: the silica framework, the hydrophobic interior of the alkyl chains, and the organic-inorganic ionic interface. Anomalous CO(2) adsorption sites were found to be well-ordered locations on the ionic interface fabricated by the π-π-stacked imidazolium heads containing inorganic anions and polar silica surfaces.
一种基于烷基咪唑鎓的长链离子液体（LCIL）通过超分子组装方法固定在硅纳米孔中。为了讨论受限纳米空间中 LCIL 的特征，除了主体材料的特征外，我们还制备了具有单分散形态和纳米结构的二氧化硅主体来固定 LCIL。该纳米结构由三个不同的区域组成：二氧化硅骨架、烷基链的疏水区和有机-无机离子界面。在由含有无机阴离子的π-π堆积咪唑鎓头和极性硅表面构成的离子界面上，发现了具有有序位置的异常 CO2 吸附位。
