Supramolecular chiral cubic phases formed by folic acid derivatives
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.
