Uncovering new properties of imidazolium salts: Cl− transport and supramolecular regulation of their transmembrane activityElectronic supplementary information (ESI) available: Experimental details, synthetic procedure, NMR, fluorescence and molecular modeling data. See DOI: 10.1039/c0cc04280c

We report the Cl − transport activity for three imidazolium-based transporters. We present significant findings regarding the use of α-cyclodextrin and cucurbit[7]uril macrocycles to form inclusion complexes with these salts and to inhibit their membrane activity. We report the Cl − transport activity of one active imidazolium salt and its inhibition by the formation of inclusion complexes.
