Supramolecular ionogels were prepared by self-assembly of small molecules through host guest interaction between beta-cyclodextrin (beta-CD) and a room-temperature ionic liquid (IL) 3-(1-methyl-3 -imidazolio)propanesulfonate-lithium bis(trifluoromethanesulfonyl)imide (MIPS-LiTFSI) which contains zwitterion MIPS. F-19 NMR and 2D ROESY (HNMR)-H-1 have been used to prove that only TFSI-is involved in the complexation. H-1 NMR, FT-IR, and comparative tests indicated that the electrostatic interaction between imidazole cation and TFSI-anion and intermolecular hydrogen bonding between three compounds also contribute to the formation of supramolecular ionogel. Ionogels with different gel sol phase transition temperatures can be obtained by adjusting the molar ratio between beta-CD and MIPS-LiTFSI. In addition, the supramolecular ionogels composed of "channel type" structural beta-CD have been constructed. The ionogel with high conductivity and low activation energy open a door to new fields for special applications.
