## Abstract In solvents such as chloroform or benzene, tetraurea calix[4]arenes **1** form dimeric capsules in which one solvent molecule is usually included as guest. To explore the structural requirements for the formation of such hydrogenβbonded dimers we replaced one __p__βtolylurea residue by
Two [2] catenanes, in which one calix [4]arene subunit is incorporated into the tetracationic ring, have been synthesized, the calix[4]arene moieties influence remarkably the conformation and solubility of the resulting catenanes.
