Ternary Amphiphiles with Star-Like Shape

1 Ternary Amphiphiles with Star-Like Shape 

Lehmann et al. developed the concept of star-shaped molecules composed of three phenylbenzoate based rod-like cores directly connected by ester groups to a central 

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 

13 The mesophase stabilization by the fluorophobic effect is remarkably large for compound 176a (Colj.ee/p2mg 144 °C SmA 174 °C Iso) [295] and compound 176b Colrec/p2mg 88 °C SmA 167 ° Iso [299] if compared to the related non-fluorinated compound (Cololtho 53 °C Iso) [295] (Fig. 47).
