Synthesis and Characterization of Terthiophene-based Rod-like Liquid Crystals

摘要：

　　With 2,2,5,2-Terthiophene as starting material,two liquid crystalline compounds containing Schiffs base unit were synthesized in this paper.The structure of the compounds was confirmed by FTIR and 1H NMR.The thermally induced phase transition behaviors were investigated by POM and DSC,and the temperature ranges of liquid crystal phase of the two compounds were compared.Results showed that the symmetric compound exhibited a lower clearing point temperature and broader temperature range of liquid crystal phase.
