我们合成了一系列热致液晶叶酸衍生物，它们在寡聚谷氨酸部分具有分级手性结构。叶酸与钠盐的配合物显示六方柱状和Pm3n立方相。盐的加入诱导了柱相和立方相中的超分子手性。谷氨酸寡聚体的分子手性的调节对它们的超分子手性结构有很大影响。
We have prepared a series of thermotropic liquid-crystalline folate derivatives which have hierarchical chiral structures at the oligo(glutamic acid) parts. The complexes of the folic acids with sodium salts show hexagonal columnar and Pm3n cubic phases. The addition of the salts induces supramolecular chirality in the columnar and cubic phases. Tuning of molecular chirality at the oligo, (glutamic acid) moieties greatly affects their supramolecular chiral structures.
