摘要：

Schiff-base macrocycles 1, which have a crown ether-like interior, form ionic nematic lyotropic liquid crystals in various organic solvents when functionalized with long alkoxy substituents and complexed to diverse ammonium and alkali metal salts. From X-ray diffraction and transmission electron microscopy studies, and by comparison with the organization of macrocycles functionalized with shorter chains, these macrocycles assemble into lyotropic liquid crystals where the macrocycles are stacked and the cation is included in their interiors.
