Research Abstract	Alkylimidazolium-based long-chain ionic liquid (LCIL) was immobilized in silica nanopores via supramolecular assembling approach. In order to discuss the characteristic features of LCIL in confined nanospace except the characteristic of the host materials, we have prepared the silica host with monodisperse morphology and nanostructure 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. The supramolecular self-assembling approach provided opportunities for the homogeneous confinement of molecules in well-ordered nanopores. We speculate that the restricted motion of the head groups is due to the π-πstacking interactions between imidazolium rings and the electrostatic interactions with silica polar surface.
