✦ Synopsis

We report herein the observation of a hexameric structure of only by hydrogen bonds. The tendency to form aggregates in solution is demonstrated mainly by means of ESI-MS a hydroxyresorc [4]arene in the solid state, enclosing a large interior space. This artificial molecular container is stabilized methods.
