N,N'-disubstituted methylenediimidazolium salts: a versatile guest for various macrocycles.
N,N'-Disubstituted methylenediimidazolium salts allow the formation of flexible inclusion complexes with beta-cyclodextrin, cucurbit[7]uril, tetrapropoxycalix[4]arene, and dibenzo-24-crown-8 ether. Due to the salt nature of the imidazolium guest, the counterion largely determines its solubility in a given solvent. Moreover, by the judicious choice of the imidazolium substituents, inclusion complexes of guest salts were obtained with a variety of macrocyclic hosts, and the binding parameters of the inclusion were determined for each complex.
