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. (P. Metrangolo, G. Resnati, et al., September 3, Adv. Mater. 2002, 14, 1197-1201)
