Supramolecular Route to Fluorinated Coatings: Self-Assembly Between Poly(4-vinylpyridines) and Haloperfluorocarbons

A simple supramolecular method for the direct self-assembly of comb-like complexes composed of hydrocarbon polymers and perfluorocarbon mesogens is described. Halogen bonding is highly directional, so that perfluoroalkyl residues with their rigid rod-like architecture result in materials with a beautiful comb-like structure. The Figure shows an ORTEP view of such co-crystals.
