Inverted cucurbit[6]uril supramolecular assemblies formed in the presence of tetrachlorozincate anions

Abstract We investigated the interactions in an inverted cucurbit[6]uril ( i Q[6]) with a series of 1, ω -alkyldimins and their supramolecular assemblies in the presence of the tetrachlorozincate anion ([ZnCl 4 ] 2− ) structure directing agent. i Q[6] forms an outer surface interaction with [ZnCl 4 ] 2− to form different i Q[6]/[ZnCl 4 ] 2− -based supramolecular assemblies with different length 1,ω-alkyldimins. Interestingly, most 1,ω-alkyldimins were not visible in crystals structures in the presence of concentrated HCl. The porous i Q[6]/[ZnCl 4 ] 2− -based supramolecular assemblies could be used as materials for adsorbing volatile compounds.
