Thermotropic ionic nematics with moderate transition
temperatures are obtained by dissolving alkali metal salts within
nematogens bearing a crown ether moiety; in these media, the ions show a
significant ‘apparent ionic order’ as measured by quadrupolar
NMR spectroscopy.
通过将碱
金属盐溶解于含有冠状醚基团的液晶剂中,获得了具有适中转变温度的热响应型离子液晶;在这些介质中,离子表现出显著的“表观离子有序性”,这一性质通过四极核磁共振波谱技术得以测定。
