Description
| - A co-polysiloxane has been prepared with an asymmetric bent-shaped side group based on a liquid crystalline monomer exhibiting the B2 (SmCP) phase, namely [4-(4’-undecenyloxy)biphenyl] [4-(4’-octyloxybiphenyl)-oxycarbonyl-4-(2-methoxyphenyl)] isophthalate. In order to dilute the side chain mesogens along the polymer backbone the octyl side chains were also incorporated. The X-ray studies confirmed that resulting co-polysiloxane exhibits a liquid crystalline layered phase, the siloxane polymer chains being microphase segregated from the incompatible side chain mesogens. The mesophase of polymer exhibits the homeotropic structure that can be successfully aligned by unidirectional shear. This phase does not exhibit polar switching under an applied electric field unlike the bent-core monomer, used as the side chains of this polymer. This can be caused by the homeotropic alignment of the polymer samples.
