Unique effect of the electric field on a new liquid crystalline lactic acid derivative
Original language description
A new chiral lactic acid derivative is presented, exhibiting a frustrated liquid crystalline phase, namely the orthogonal twist grain boundary TGBA phase in a broad temperature interval. Unique effect is observed and found that the applied electric fieldreversibly transforms the planar TGBA texture to the homeotropic one, homogeneously dark in crossed polarizers. The unusual behavior of the TGBA phase under the electric field can be explained by the specific packing of molecules within the smectic layers, resulting in relatively high layer compressibility, which lowers the energy of structural defects and thus facilitates the structure transformation.
