Abstract:	Four new series of ionic liquid crystals derived from imidazole bromonium and benzimidazole bromonium salts with spacer alkyl chain (Cn, n = 2, 4) were synthesised and characterised. The following tests and measurements have been performed: the FT-IR, 1H-NMR and 13C-NMR spectroscopy in addition to a CHN elemental analysis techniques. Both the differential scanning calorimetry and the polarising optical microscopy measurements are applied for the evaluation of liquid crystals properties. The outcome confirms the existence of a smectic A liquid crystalline phase. A Density Functional Theory computations were performed to obtain the shape of the molecular structure that corresponds to the ground-state energy.
