In this thesis Johanna Bruckner experiences the invention of the lyotropic counterpart of the thermotropic SmC* part, which has develop into well-known because the in simple terms spontaneously polarized, ferroelectric fluid in nature. by way of polarizing optical microscopy, X-ray diffraction and electro-optic experiments she firmly establishes facets of the constitution of the radical lyotropic liquid crystalline section and elucidates its attention-grabbing houses, between them a mentioned polar electro-optic influence, analogous to the ferroelectric switching of its thermotropic counterpart. The helical flooring nation of the mesophase increases the elemental query of ways chiral interactions are "communicated" throughout layers of roughly disordered and achiral solvent molecules that are positioned among adjoining bi-layers of the chiral amphiphile molecules. This thesis bridges a major hole among thermotropic and lyotropic liquid crystals and pioneers a brand new box of liquid crystal research.
