The molecular structures of the intermediates and target compounds were confirmed by elemental analyses and FT-IR, ^1H NMR and mass spectrometry. The mesomorphic behaviors were investigated by polarizing optical microscopy （POM） attached with hot stage and differential scanning calorimetry （DSC）. Enantiotropic smectic 1, smectic A, blue phase and cholesteric mesophases are exhibited by the newly synthesized compounds.展开更多
