A series of novel star-shaped ionic liquid crystals (ILCs) compounds with various counterions (derived from HBF4, HPF6, CF3COOH, d-MH-SO3H, H3PO4, p-Toluenesulfonic acid) were designed and synthesised starting precursors pyridines crystalline monomer cholesteryl 4-bromobutanoate. Inducing by use self-assembly due to electrostatic attraction ion clusters was one the most essential factors for intermolecular separation. The chemical structures, properties, behaviour conductivity these researched during multiple experimental techniques. ILCs showed a smectic (SmA) mesophase. d-spacing increased slightly increase volume anion. clearing temperatures pyridinium salts suggested that effect stabilisation on SmA structures in order H2PO4−>BF4−>TS−>D-MH-SO3−>CF3COO−>PF6−.

The synthesis and characterization of novel ionic liquid crystals based on pyridinium salts with Br− PF6− counterions are described in this work. These were derived from 4-hydroxypyridine, both by N- O-alkylation. 3,4,5-tri(alkyloxy)-benzyl mesogenic unit was attached to the nitrogen atom ring. Alkyl chains a different number carbon atoms (6, 8, 10, 12 14) employed order show effect stability mesophase. POM (polarizing optical microscopy) XRD (powder X-ray diffraction) studies indicated that bromide shorter C6, C8 C10 do not mesomorphic properties, while longer chain analogues C12 C14 exhibit two enantiotropic columnar phases. Surprisingly, larger size counterion crystal properties.

Fluorescent liquid crystal polymers have attracted much attention because of the combination fluorescence, crystallinity and processability. In this study, we designed synthesised two series photoluminescent cholesteric polysiloxanes, which contained cholesterol mesogens fluorescein methyl ester with different side chain lengths. The chemical structures properties were investigated by usual methods. property characterised fluorescence spectroscopy. At same time, effects lengths fluorescent group chains on studied. results showed that possessing very good properties, may has certain practical value application prospect.
