Dendritic benzamides

Percec et al. described the self-assembly of Rp-substituted bis-dendritic benzamides, such as compounds 179a and 179b, combining a dendron decorated with perfluorinated chains and a dendron with alkyl chains. In the hexagonal columnar LC phases of these molecules the smaller alkyl chains form the centers of the columns, the aromatics are arranged in cylindrical shells surrounding the aliphatic columns, while the larger fluorinated chains form a fluorous continuum... 

Small molecules can undergo self-organization into a wide variety of orientations besides nanotubes. For example, in 2003, Percec designed a system of self-assembled dendritic benzamides based on methyl gallate and trimethoxyben-zene that exhibited a liquid crystalline phase both as monomers and as polymers (Fig. 7.7) [52],...
