Abstract

We synthesized and characterized a novel discotic liquid crystalline material (THOB) composed of 1,3,5-tri-substituted benzene core and 2-(4-hexyloxyphenyl)-oxadiazol-5-yl arms. Chemical structure of THOB was characterized using 1H-NMR and mass spectroscopy and its thermal behavior was determined using DSC and polarized optical microscopy. THOB showed narrow mesophase region at around 128°C and exhibited nematic-like texture.
