In this thesis Johanna Bruckner stories the invention of the lyotropic counterpart of the thermotropic SmC* section, which has turn into recognized because the in basic terms spontaneously polarized, ferroelectric fluid in nature. via polarizing optical microscopy, X-ray diffraction and electro-optic experiments she firmly establishes points of the constitution of the unconventional lyotropic liquid crystalline part and elucidates its attention-grabbing homes, between them a said polar electro-optic impression, analogous to the ferroelectric switching of its thermotropic counterpart. The helical floor country of the mesophase increases the elemental query of ways chiral interactions are "communicated" throughout layers of roughly disordered and achiral solvent molecules that are situated among adjoining bi-layers of the chiral amphiphile molecules. This thesis bridges an incredible hole among thermotropic and lyotropic liquid crystals and pioneers a brand new box of liquid crystal research.

The basic motif of all surfactant molecules used is a 2-phenylpyrimidine core with a heptyl chain attached to the 5-position of the pyrimidine ring.
