Illuminating host–guest cocrystallization between pyrogallol[4]arenes and the ionic liquid 1-ethyl-3-methylimidazolium ethylsulfate

Abstract

The host–guest complexes of seven unique cocrystals containing pyrogallol[4]arenes and the ionic liquid 1-ethyl-3-methylimidazolium ethylsulfate are fully described. The investigation of these cocrystals is directed at expanding the control of the solid-state structures of these unique host–guest assemblies. The effects of varying conditions such as solvent choice and aliphatic tail length appended on the host macrocycle are explored and shed new light on the resultant supramolecular structures.
