appreciable effects. Furthermore, zinc(II) porphyrins 1-Zn and TriCP-Zn bound potassium cations forming dimericassemblies 2, as demonstrated by the absorption and 1H NMR spectra. Although DCP-Zn and MCP-Zn were also capable of forming dimers, the highest stability and the largest level of attraction between

nature of the halogen bond assembly. The crystal lattice of 1 contains two structurally different dimericassemblies A and B, formally resulting in the mixture of a capsular dimer and a dimeric pseudo-capsule. 1H and 19F NMR analyses supports the existence of these halogen-bonded complexes and enhanced
guest inclusion in solution.

The construction of specific supramolecular assemblies based on the directional non-covalent bonding has been a central goal of
