摘　　要：设计并合成了４个单臂冠醚液晶，考察了冠醚环与亲酯性结构单元之间的桥键与液晶性质的关系，中心桥键对单臂冠醚液晶的熔点影响不大，而对液晶热稳定性有较大的影响．Four monoarmed crown ether liquid crystals were designed and synthesized. The relationship between the properties of liquid crystal and central bridge bond that contact the crown ether and lipophilic structural unit was investigated. The melting point of crown ether liquid crystals was changed a little by variation central bridged bond. The various central bridged bonds change the stability of liquid crystalline phase. The order of clearing point is _NCH_ > _NN_ > _O_CO_ > _HN_CO_.
