Another type of MJLCP BCPs has been syntheisized using bent core LCs
(BCLCs) (Chen et al. 2006; Tenneti et al. 2008). Poly[styrene-block-{3,5-bis
[(4
0 -((4
00 -tetradecanoylbenzoyl)oxy)benzoyl)oxy]styrene}] (PS-b-PTBOS) as the
rod (Chen et al. 2006). The five-ring mesogen ensures a rigid core of the rod with a
relatively large diameter while the 14-C tails of the mesogen render a relatively
thick “shell.”
Fig. 10 TEM micrographs of thin sections of PS 171 -b-PMPCS 32 . The sample was sectioned along
the xz (a), yz (b), and xy (c) planes followed by RuO 4 staining for 30 min. Insets show their FFT
pattern (Tenneti et al. 2005)
Fig. 11 Schematic representations of asymmetric PS-b-PMPCS TPL hierarchical structure. Note
the rods are parallel to the lamellar normal (Tenneti et al. 2005)
