title: Ion-pair induced self-assembly of molecular barrels with encapsulated tetraalkylammonium cations based on a bis-trisurea stave.
abstract: A bis-trisurea ligand assembles with the tetraalkylammonium halides to form the flat 'stave' structures or 'barrels' that encapsulate multiple R(4)N(+) guests, depending on the size of the halide anion (Cl(-) or Br(-)) and the R(4)N(+) cation.
