CONDUCTIVITY OF THERMOTROPIC IONIC LIQUID CRYSTALS

Thermotropic Ionic Liquid Crystals

The last five years' achievements in the synthesis and investigation of thermotropic ionic liquid crystals are reviewed. The present review describes the mesomorphic properties displayed by organic, as well as metal-containing ionic mesogens. In addition, a short overview on the ionic polymer and self-assembled liquid crystals is given. Potential and actual applications of ionic mesogens are al...

Thermotropic liquid crystals from biomacromolecules.

Complexation of biomacromolecules (e.g., nucleic acids, proteins, or viruses) with surfactants containing flexible alkyl tails, followed by dehydration, is shown to be a simple generic method for the production of thermotropic liquid crystals. The anhydrous smectic phases that result exhibit biomacromolecular sublayers intercalated between aliphatic hydrocarbon sublayers at or near room tempera...

Thermotropic liquid crystals from engineered polypeptides

Phase modulation of thermotropic liquid crystals of tetra-n-alkylammonium polyoxometalate ionic complexes.

A series of composition analogous polyoxometalate-based ionic complexes are synthesized and studied, with a focus on the correlation between their mesomorphic behavior and their chemical structure. Generally, these polarizable rigid polyoxoanion clusters decorated with hydrophobic flexible alkyl chains have demonstrated a propensity to form thermotropic liquid-crystalline (LC) phases. Character...
