Abstract

original image

Two faces: Semifluorinated Janus-dendritic benzamides self-assemble into supramolecular bilayered pyramidal columns with diameters over twofold greater than those of columns generated from twin-dendritic benzamides (see model). The Janus-dendritic benzamides are synthesized by selectively replacing the aliphatic chains from the periphery of one of the two dendrons of a twin-dendritic benzamide with semifluorinated chains.
