Abstract: A new polymeric material, a process for forming the material and method of using the material to separate enantiomers of chiral compounds, particularly amino acids and pharmaceuticals are disclosed. A polymeric material can be formed from polyaniline doped with a chiral acid and then extracted with a suitable base. This leaves behind a polymeric material which preferentially traps, and then selectively releases, one enantiomer of a chiral mixture brought in contact with the surface of the polymeric material. In particular, when polyaniline is doped with either R- or S-camphorsulfonic acid (CSA) it takes on a chiral structure. Removing the chiral acid dopant leads to a new chiral polyaniline. The dedoped chiral polyanilines have the ability to discriminate among enantiomers of many compounds which exist in chiral mixtures.
