Complexation constants with the macrocyclic azoniacyclophane CP44 and phenyl guest compounds with at least four fluorine atoms or alternatively protons at the ring were obtained by NMR shift titrations in water. The fluorinated compounds show free energies of complexation which are smaller by ⌬⌬G =

✦ Synopsis
3,5-Dinitro-4-methylbenzoic acid functions as a host accommodating guest molecules in cavities created due to the coupling of six neighbouring molecules through hydrogen bonding. 2,6-Dimethylnaphthalene is encapsulated within the cavity unlike naphthalene. It is thought that the latter is not able to effectively fill the cavity.
