The structures of compounds were characterized by elemental analysis, UV-Vis, FTIR photoacoustic spectrum, 1H NMR and MS. The domains of stability and the structure of the liquid crystalline phases were determined by optical microscopy, differential scanning calorimetry (DSC). According to the DSC thermogram of compounds, compound(3) exhibits lower phase transition temperature at - 36℃ and a wide mesophase range in 175℃.展开更多
