AbstractA series of alkoxy-substituted hydroxybutyl dibenzoates and four halogen-substituted compounds were synthesised in quantitative yields. The structures of the molecules were confirmed by Fourier transform infra-red, (1)H nuclear magnetic resonance (NMR) and (13)C-NMR spectroscopy and gas chromatography-mass spectrometry. The stabilities of the synthesised compounds were determined by thermogravimetric analysis. The mesomorphic behaviour was investigated using differential scanning calorimetry, polarising optical microscopy and wide-angle X-ray diffraction (WAXD) analysis. It was observed that the compounds with alkoxy tails form the typical fan-like texture of a smectic liquid crystalline phase between the melting point and clearing temperature. WAXD experiments confirmed the formation of smectic liquid crystalline phases. The halogen-substituted compounds were incapable of forming the liquid crystalline phase on heating.
