The biogenic tetraamines, spermine and norspermine, are efficiently encapsulated in the solid state by two molecules of carboxylcalix[5]arene, by means of a highly regioselective proton-transfer followed by bisendo-cavity inclusion, providing overall-neutral complexes with a 70–72% packing coefficient, despite the modest affinity shown in solution.

Abstract
The biogenic tetraamines, spermine and norspermine, are efficiently encapsulated in the solid state by two molecules of carboxylcalix[5]arene, by means of a highly regioselective proton-transfer followed by bisendo-cavity inclusion, providing overall-neutral complexes with a 70–72% packing coefficient, despite the modest affinity shown in solution.File in questo prodotto:
