Synthesis of 5-3,6,7,10,11-pentakispentyloxytriphenylen-2-yloxypentyl Methacrylate and Its Mesomorphism Study

摘要

A novel triphenylene-based discotic liquid crystal 5-3,6,7,10,11-pentakispentyloxytriphenylen-2-yloxypentyl methacrylate was successfully synthesized. Chemical structure of this compound was determined by H-NMR and FT-IR spectrum, and its mesomorphism was investigated under the guidance of differential scanning calorimeter (DSC) and polarizing optical microscopy (POM) method. This compound apparently exhibited a classical texture of columnar phase in the mesophase temperature. The double bond on the side chain made it possible for this compound to be a candidate of designing and synthesizing liquid crystal polymer.
