Preparation and study the structural properties and magnetic susceptibility of a liquid crystal

الملخص EN

Two ligands have been synthesized from benzidine and hydrazine derivatives.

These ligands have been mixed with metal ions such as CuII and NiII to synthesis liquid crystalline complexes.

By using polarizing optical microscopy (POM) techniques, it is found that these prepared compounds have liquid crystalline behavior and characterization by physical and chemical techniques such as spectroscopic (UV-Visible, FT-IR, X-ray powder diffraction (XRD)), magnetic susceptibility, and molar conductivity.

The aim of the study show enantiotropy nematic phase (marble and schleiren textures through heating and cooling respectively) for all compounds, the prepared complexes are paramagnetic, and study their structural, and magnetic susceptibility.
