Phenyl-perfluorophenyl polar-πinteractions have been revisited for the design and fabrication of functional supramolecular systems. The relatively weak associative interactions (ΔG ≈ -1.0 kcal/mol) have limited their use in aqueous self-assembly to date.

A solid-state structural study on anion-π interaction in various N-(pentafluorobenzyl)pyridinium salts accompanied by NMR spectroscopic investigations is presented. The crystal structures of 1a-1d reveal different kinds of contacts with anions, including anion-π interactions. In particular, the solid-state structure of 1b-I3 shows distinct evidence of anion-π interactions. Attempts to study anion-π interactions in solution were not successful, but their presence in solution could not be ruled out. The interactions of N-(pentafluorobenzyl)pyridinium salts are investigated in the solid state as well as in solution. The triiodide salt shows distinct evidence of anion-π interactions with both the pyridinium and the pentafluorophenyl unit. Solution investigations to prove the attractive nature of the noncovalent force failed, but they did not rule out the presence of the interaction. Copyright
