Differentially functionalized acyclic cucurbiturils: synthesis, self-assembly and CB[6]-induced allosteric guest binding†
Abstract
We report the synthesis of mono- and difunctionalized acyclic cucurbit[n]uril-type containers (1HA, 1HDA, 2HDA) which bear hexylammonium and hexanediammonium arms. The intra- and intermolecular assembly processes of 1HA, 1HDA, 2HDA as well as the ability of CB[n] to trigger allosteric host–guest binding toward guests 9–11 are presented.
