“…42 The stability of these mesophases was significantly increased by replacing the alkyl chains with semifluorinated chains (compound 4a), due to the enhanced incompatibility of such chains with the aromatic cores. 43 With such compounds it was possible to change the mesophase morphology from lamellar (compound 3a) via bicontinuous cubic (Cub V , compound 3b) 46 and hexagonal columnar (Col h , compound 4a) to micellar cubic (Cub I , lattice: Pm3n, compound 5) by changing the number and the length of the semifluorinated chains (Fig. 4a).…”

“…62 Changing the number of semifluorinated chains and manipulation of their length allowed a directed tailoring of the mesophase morphology. In this way a transition from a lamellar via a bicontinuous cubic (Cub V ) 63 and a hexagonal columnar (Col h ) to a micellar cubic mesophase (Cub I , lattice: Pm3n) was possible on increasing the number of fluorinated chains, as shown in Fig. 7.…”
