Abstract
A novel triphenylene-based discotic liquid crystal 2-allyloxy-3,6,7,10,11-penta-pentyloxytriphenylene was firstly synthesized. The chemical structure was determined by 1H-NMR and Fourier transform infrared spectrometer (FT-IR), and its mesophase was investigated by differential scanning calorimeter (DSC) and polarizing optical microscopy (POM) methods. It has a large range of mesophase from 111 °C to room temperature. During the cooling process, liquid crystal textures with typical conical fan shape were observed.
