A series of novel Schiff base crown ether liquid crystals were synthesized from intermediates 4-(4'-alkoxylbiphenyl-4-carboxyl) benzaldehyde and diaminodibenzo-15-crown-5 in yields of 95.2%~96.7%,and their structures and properties were characterized by elemental analysis,polarimetry,¹H NMR,IR,MALDI-TOF-MS,DSC and polarizing optical microscopy with a heating stage.It was found that end products 6Ⅰ and 6Ⅱ formed liquid crystalline phase when heated to their melting points.In their liquid crystalline state,typical chiral smectic C phase,smectic phase,cholesteric phase,and nematic phase textures can be observed.The smectic phase temperature range increases,but the smectic-nematic transition temperature and nemetic phase temperature rang decrease with the increasing of the carbon number of end alkoxy groups,and the melting point (T_m) and isotropization temperature (T_i) decrease gradually.
